The first Technical Series meeting of the 2019-2020 season took place on September 24. BCA member Doug Paul gave a presentation on astrophotography, a pursuit that he took up in earnest upon his retirement. He shared a wide variety of images followed by a detailed description of the equipment, methods, and software he uses to capture his gorgeous images of Deep Space Objects. Doug had the session videotaped and you can watch it in full at this link. On that YouTube page there is more explanation and a table of contents with time codes pointing to the sections of the video .

Doug also supplied a list of references. These are all active links to resources you can access on the web.

Digital Infrared Photography - Vega Buchbinder

Vega Buchbinder gave a stimulating presentation on digital infrared (IR) photography at the February 26 Technical Series meeting. She discussed the principles of IR imaging and gave an overview of the equipment and techniques for capturing this invisible part of the spectrum. There was active engagement responding to the many questions from those in attendance. Vega has shared her presentation in pdf format, downloadable from the link below.

How to Improve Your Printing - Pip Shepley

BCA Photo Group member Pip Shepley gave an informative and well-received presentation on printing at our January 22 Technical Series meeting, with approximately 30 people in attendance. Pip talked about his own long journey in improving his printing and shared techniques and tips from the numerous classes he has taken, studying under some of the leaders in the field. The talking points were supported by live demos of workflow cases in both Photoshop and Lightroom, the use of soft proofing, and the use of test images to see how well the monitor and the printer reproduce tonal ranges.

Pip has provided us with a set of digital files that you can download here by clicking on the entry:

Member-Centered Topics Night

On November 27 we had our first Technical Series meeting with a new format specifically designed to draw on the collective knowledge and expertise of the diverse BCA membership. The evening was divided into three time slots. In each section a group member gave a short prepared introduction to a topic that was of interest both to that person, and to the group in general. The presentations and the ensuing discussions were highly participatory, with members in the audience either asking questions or adding their own thoughts on the topic.

William Feiring led off with a discussion of online learning resources. He focused initially on, a rich source of professionally prepared courses. While Lynda is normally a fee-based site, virtually anyone can get free access either via their home town library or with a Boston Public Library eCard. William and other members also mentioned a number of other resources that they use, including Adobe, Scott Kelby, Julianne Kost, Tim Grey, and others. Instructions on accessing and links to the above resources and more can be found in William’s summary.

Ann Sluder talked about custom photo calendars as a means for sharing themed collections or portfolios. She uses this personally as a way to preserve and share her work, as an alternative to hanging prints or seeking gallery space. Ann brought in several of her past calendars. Some of the ways she uses these - document a trip; capture favorite places; select images that will be meaningful to someone she gives the calendar to as a gift. The possibilities are endless. Other members then talked about other ways to share work - photo books, greeting cards, jigsaw puzzles, printing on fabric or tile, clothing, and more. Ann’s slides include links to several providers that she has used for calendar creation.

Mark Levinson gave an informative presentation on inkjet printer papers. He covered Base Materials (paper types), Surfaces (glossy, etc.), Color/Brightness, Ink Types, Longevity, and Sizes. Mark brought along prints of two images - one color, one black & white - as examples. Each had been printed on quite a few different paper types so that members could compare the appearance for themselves. More info in Mark’s slides.

My 5 Best Shots - hosted by Dennis Rainville

BCA Photo Group founding member Dennis Rainville once again hosted the popular 'My 5 Best Shots' session. This was our last meeting of the spring, and a chance for members to talk about their photo efforts over the last year. The intent is not to showcase what you consider your 'top shots', but rather to talk about what you have been doing with photography over the past year. Members were invited to submit up to 5 images for sharing. For some it was trying out new techniques and genres (long exposure, night photography, street photography, portraits, etc.), for others it was about travel and new experiences, and for others it was the relationship between their photography and their personal and emotional lives. This format has proved to be a terrific way for us to share more about our photography with our fellow members than we do in the usual meeting formats.

The images shared in the meeting appear in the gallery here, grouped by photographer in the order presented.

Food Photography - Catrine Kelty

Catrine Kelty gave a mouth-watering presentation about her work as a food stylist. Catrine has had a long and active career working with chefs, restaurants, and photographers to get the images that you see in magazines and cookbooks, and on web sites. The meeting was very interactive, with active questioning from the attendees. We learned a lot about this niche of the photography business!

Photo Painting ... by Fran Forman

At our April 22 Technical Series meeting approximately 40 BCA members and guests were treated to an inspirational introduction to Fran Forman’s remarkable world of creativity and imagination. Fran is an internationally recognized, award-winning artist who works in a technique she calls Photo Painting. Primarily using Photoshop and a Wacom tablet, she composites elements from multiple photographic images, modifies and blends them, adds color and texture, and more, to create compelling flights of fancy. Hers is truly a world of infinite possibility, with the outcome determined only by the artist’s own sensibility. The evening was highly interactive, with many questions from the group about her inspiration and process, and how those have evolved over time. It is well worth a visit to Fran’s web site at to read more about her and to see a selection of her work.

The Lensbaby line of special effects lenses was the subject of our March 27 2018 Technical Series meeting. Emily Hojnowski, head educator at Hunt's Photo, brought knowledge, enthusiasm, and a collection of lenses and props! She opened the meeting with a slide show overview of the Lensbaby line. They are all prime, fully manual lenses, and each one has its own characteristics of blur, 'twist', 'glow', tilt shift, and more.

Many of the BCA members brought their camera bodies, and Emily had a good selection of lenses with mounts for different camera types (Nikon, Fuji, Canon, etc.). We chose lenses and then went over to the prop tables to experiment. Emily circulated to advise, teach, and troubleshoot. 

Whether or not you think you would want to add these effects to your tool kit, it was a great learning experience and a good time was had by all. I personally tried a Composer Pro II (tilt shift) with the Sweet 50 optic and found that I liked the effect I got shooting portraits. First, a shot of Emily at work.

Now a small gallery of portraits that I shot with the Sweet 50, and a shot of flowers by Bob Bass with the Velvet 56.

Technical Aspects of Night Photography

Jurgen Lobert gave an image-rich and information-packed presentation on night photography at our January 23, 2018 Technical Series meeting. He went over equipment and techniques, with specific recommendations, and examples of the kinds of images you can make at different locations. Some of the main take-aways:

  • White Balance can be challenging with varied light sources in the image, and it is helpful to at least get close 'in camera'. This may involve trial and error. Read about this on Jurgen's website.
  • Use your RGB histogram. With richly colored lights in an image it is very possible for one of the color channels to be saturated while the overall 'average' histogram looks fine.
  • Use your 'blinkies' to highlight blown-out pixels so you can adjust as needed.
  • Use low ISO for lowest noise and highest dynamic range, select f-number for artistic choice, and adjust exposure time as needed.
  • Test exposure by the technique of High ISO Preview. Set the ISO at 6400, experiment to find a good exposure (in seconds), then switch to ISO 100 and adjust the exposure time to minutes - 1 second at ISO 6400 translates to 1 minute at ISO 100. Read about this on Jurgen's website.

You can download Jurgen's list of equipment and settings at

There is of course lots more! You can find more info at Jurgen's blog page and via the list of resources on Jurgen's web site, where you can see a variety of his images. If you want to get out to shoot with him, Jurgen also runs the Greater Boston Night Photographers meetup group.

Art of Black & White Photography

Dennis Rainville gave a great presentation (as usual) to a packed house at the November 28 Technical Series meeting. His subject was 'The Art of Black & White Photography'. He opened with some general comments about B&W work and why one might choose that vs. color. Dennis then showed three images that he had been close to discarding (they just didn't work in color) but then turned into very successful B&W shots. He talked about some of the processing techniques he uses and then opened Lightroom and Photoshop and went through his workflow on several of his shots. This involved extensive use of adjustment layers and layer masks. It was a powerful demonstration of processing techniques that showed why Dennis stands by Ansel Adams' statement - 'I don't take a photograph, I make it.' Even if you don't plan to use these kinds of techniques yourself, there was a lot to learn about what makes an image come together. Dennis also also talked about some of the people whose B&W processing work has influenced him - links below.

Compositing - Expand Your Creative Space

The talented Jim Christensen gave an excellent presentation on compositing to an audience of nearly 40 attendees at the October 24 Technical Series meeting. Compositing is the art of combining elements from more than one image into a unified whole. Jim gave an introduction to the long history of compositing in photography, going back to the 1800's. He then showed a number of striking examples from his own body of work and then he demonstrated his process step by step for several images, using Photoshop tools to select, layer, mask and adjust the images to achieve the desired effect. The information on how to make these changes non-destructively could be applied even to single images, so it was valuable even if you don't plan to do compositing yourself.

Jim had a two-part course on how to use layers and how to fix common problems in Photoshop available for sale at the end of the presentation, and they proved to be quite popular.

You can download the pdf of Jim's meeting handout at this link.

Concert Photography

Marv Goldschmitt, one of our BCA Photo Group founding members, gave a terrific talk on Concert Photography for the first Technical Series presentation of the season (September 24). Marv is an accomplished concert photographer, having shot live performances by living legends such as James Cotton, Buddy Guy, J. Geils, Judy Collins, and many others.

Besides showing lots of impressive photos, Marv gave us an A to Z rundown on everything you’d need to know, but didn’t even know you’d need to know, about shooting musical performances.  He started out by relating how he got started doing concert photography in the first place, and what it takes to move up the photographic ‘food chain’ as one’s work gets better known among performers, venue staff, and promoters. His presentation was then divided into what you do ‘Before’, ‘During’, and ‘After’ the shoot, covering permissions, security, scouting the locations, studying acts in advance (YouTube!), working with and around performers and audiences, his post-processing workflow, and much more. He also went over recommended equipment, lenses and exposure settings.

Here are some resources that Marv recommended, and a link to the source of the convenient dual camera strap that he uses:

The Art of Digital Photography

The May 23 Technical Series meeting reinforced how fortunate we are to have Dennis Rainville as a member of the BCA Photo Group, and also as the leader of the Tech Series and a veteran presenter. His topic for the evening was ‘The Art of Digital Photography’. 

Dennis set the stage for the talk by telling us about his own history – an early predilection toward art combined with a career in technology. His photography enables him to combine these to good effect. Knowing that many people are resistant to post-processing of almost any kind, Dennis pointed to a well-known quote from Ansel Adams – ‘You don’t take a photograph, you make it.’ The camera and the brain are two different things and the camera can rarely record what the eye/brain can perceive. Processing can bridge the gap.

With that introduction, Dennis touched on a series of techniques that he has employed, sometimes singly and sometimes in combination. This was not a thorough how-to, but rather a richly illustrated demonstration of the art of the possible, and from that the possibility of art. His before and after slides showed how the application of each technique changed an image for the better. Below is a list of the techniques he discussed, along with the main tools he uses for each:

  • HDR - Lightroom
  • Focus Stacking - Helicon Focus
  • Panoramas - Lightroom and Photoshop
  • Black & White Conversion - Nik Silver Efex Pro
  • Textured Florals -
  • Long Exposure - Lightroom
  • Architectural Photography - Lightroom and Photoshop
  • Timelapse - Lightroom and LRTimelapse
  • LEBWFAAP - Lightroom and Photoshop

Dennis told us that he has generally set a yearly goal for himself to learn and master a new technique, methodically adding to his artistic toolkit. The last item in the list above is a combination of several of the techniques that went before – Long Exposure Black & White Fine Art Architectural Photography.

Dennis’s work is varied and beautiful and you can see a selection on his web site,


Bird Photography: Insights and Inspiration

Mike Milicia gave a great presentation on bird photography (about which he knows more than a little) at our April 25 meeting. He was not scheduled to present but very graciously stepped in when the original presenter was forced to cancel with just a few days notice. We are grateful both for his dedication and his expertise.

Mike addressed a question that he often gets when he is out running bird photography workshops - "Why doesn't MY shot look like that?" (in comparison of course to Mike's own shots). He went through a lot of the things he has learned in his many years of bird photography - knowing where to be to find subjects; getting out at the right time of day and paying attention to sun altitude and azimuth; shooting angle (especially getting down to eye level); burst mode to capture small changes in position; camera settings; use of longer lenses; focus techniques; and more. Mike talked about features that differentiate a great shot from a good shot. Things like small differences in the way the bird's head is turned; capturing behavior; catch light in the eyes ... . All of these were illustrated with photographs that really showed how each little thing made a big difference. 

The meeting was well attended by members of the Photo Group, and there were several non-members who came because they knew Mike would be presenting. If you want to see more of Mike's work (and you should), check out his web siteFacebook, and Instagram

Demystifying Flash: The Basics

Contributed by Marv Goldschmitt

At our March 28 meeting Mike Milicia, a nationally known bird photographer, teacher and founding member of the BCA Photo Group, gave a presentation to the group on the fundamentals of speedlight flash photography.

Artificial lighting is a huge topic that can take years to master. And as Mike pointed out, even with all the information that is available, there is very little that explains the basics of speedlights in a straightforward way. For many advanced photographers the vagaries of the details for optimizing their use of even a single speedlight can be daunting. As usual, Mike stepped into the breach with his clear explanations of how, when and, maybe most importantly, why to use speedlights.

Mike began by demonstrating the value of flash in a situation where most of us wouldn’t naturally think to use it: outdoor nature photography. One look at the difference between a native light shot of a bird in flight or nesting and the same shot appropriately lit with a flash, made the benefits obvious. Everyone was thinking “I want to do that” and Mike then showed us how.

Mike covered a range of topics including how the lights actually work (e.g. how different levels of light are created by a speedlight), how to use a speedlight in both manual and automatic modes, the differences between various options for syncing cameras and speedlights (e.g. front and rear curtain exposure, high speed sync, etc.), the optimal distance from a subject, how to think about the balance between ambient and flash light, and much more.

From the high level of attendance and the volume of questions, it is clear that this was a topic of great interest to many members of the group. We all left with a much better understanding of a tool that we rarely use to its potential.

Mike prepared a great list of useful resources - YouTube videos and books - in a pdf document that you can access at the link below. If clicking this doesn't open on your browser, try right-clicking and do a 'save as' to download the file.


Photoshop Processing / Techniques

Posted by Charlie Mazel

BCA Photo Group member Mark Levinson gave a well-attended and well-received presentation on Photoshop techniques at the February 28 Technical Series meeting. While Mark works with Photoshop Elements himself and used that for the demonstration, everything he demonstrated is available in the full Photoshop program. This was not a 'Photoshop overview', but rather a focused demonstration of some of the most useful core tools:

  • Levels adjustment (both RGB and by individual color)
  • Hue/Saturation adjustment
  • Adjustment layers and layer masks (great for non-destructive work!)
  • Black and White conversion
  • Sharpening
  • Cloning

Mark worked with an image in real time, showing how he could make selective adjustments to achieve desired effects. Attendees could either just follow the presentation or try things for themselves - instead of the usual setup with just rows of chairs, several long tables were set up on one side of the room for people who brought their own laptops.

Of course, there is a danger in teaching people how to do things. Just because you can do something doesn't mean you should. To illustrate this, I offer a picture of Mark mid-presentation titled 'Look Ma, no hands! (with a healthy glow to the face)', showing that even someone not well versed in the tools can (mis)use them with just a little effort.


At our January 24 Technical Series meeting we were once again treated to an extremely informative presentation by a BCA Photo Group member. Mike Milicia is an accomplished nature photographer, specializing in birds. He lectures and runs workshops quite frequently and we are fortunate to have him share his expertise with us.

It is easy to give some simple guidelines (see below) for taking images in such a way that you can get the most out of them in post-processing without sacrificing quality. But the guidelines are so much more powerful when you know WHY they exist. Mike gave an overview (abbreviated from his day-long seminars) of what is going on behind the scenes in digital image capture. He made clear through explanation, diagrams, and analogy how the physics, optics, and electronics of light capture all have implications for choices you can make to maximize usable information while minimizing noise. RAW capture mode preserves the data right out of the camera sensor, giving you freedom to make adjustments after the fact. In contrast, jpeg images have already had the manufacturer's image processing algorithms applied - and with no going back.

Here are some of those guidelines:

  • Shoot RAW
  • Expose to the right (ETTR) with lowest feasible ISO
  • RGB (rather than luminosity) histogram is the best way to evaluate exposure

You can always do something because you're told, but it's so much nicer to do something because you understand. Mike helped us understand.

And you should definitely check out Mike's web site to read more about him, see many of his incredible images, and keep tabs on his speaking engagements and workshops.


On Tuesday, 10/25/16, BCA Photo Group's own Edmund Prescottano gave an informative presentation on Blue Hour Architectural Photography to an interested crowd of about 25 members (and one guest). This was part of our regular Technical Series. He talked about choosing subjects, when and how to get the shot on site, and post-processing in Lightroom and Photoshop to arrive at the final image. Edmund had taken a course on this topic taught by Keitaro Yoshioka at NESOP (New England School of Photography). 

Edmund opened the talk with a slideshow of some of his work. Check it out here: (position your cursor within the window and scroll down to view the images)

He then gave his Powerpoint presentation:

And here are a couple of his before and after shots. The 'before' is what he captured in camera, and the 'after' is the result of his Lightroom and Photoshop processing. During the presentation Edmund demonstrated his process from beginning to end on several images.

BCA Technical Series - Capture Part 1 - 10/21/14

In this presentation, we walked through all of the planning and thought process that goes into a photo, before your press the shutter button.
