Low Light Photography

The next meeting of the Pagosa Springs Photography Club will be held on February 12 at the Community United Methodist Church, 434 Lewis St. The meeting will start at 6:30 pm, but feel free to join us for socializing and discussion of various photographic topics at 6 pm. Photography Club meetings are open to the public. Please enter the Church through the side door next to the parking lot.

This month’s discussion will be on the topic of Low Light Photography. Making photos when the light is low, such as after sunset, in the deep forest, or in dimly lit interiors, has its challenges. However, modern cameras and good technique can overcome many of these and open up a new world of photographic opportunities. This month’s program will center on a 30 min video presentation on Low Light Photography by National Geographic photographer Joel Sartore. We will then discuss some of the situations where you are likely to be faced with low light, and solutions to allow making of great photographs under these challenging conditions. 

Following the program, we will have our monthly image share. Photography Club members may bring up to five images (on a flash drive) each to share and discuss. This meeting will also be available on Zoom for those who can’t attend in person. If you are not a Club member, contact abutler@mac.com for the Zoom link.

Virtual Shutter Therapy—Minimalism

Each month the Photography Club sponsors a Virtual Shutter Therapy session on our Facebook page. For the February topic, explore the art of minimalism through your lens. Focus on simplicity, negative space, and intentional composition. Highlight subtle details, clean lines, or a single striking subject. Use light and shadow to emphasize your vision. Let less tell more—what story can you convey with only the essentials? Before March 2, please share up to three photos by commenting on the post on this theme at the Club’s Facebook page, https://www.facebook.com/PagosaPhotoClub. This challenge is open to all photographers, whether a Club member or not. Please show your appreciation by liking and commenting on the works of others.

AI in Photography, August 14

The August  meeting of the Pagosa Springs Photography Club will be held on Wednesday, August 14, at the Community United Methodist Church, 434 Lewis St. Join us for social time at 6 pm; the meeting will start at 6:30 pm. Please enter the Church through the side door next to the parking lot. This month’s presentation will feature Dave Anderson, speaking about Artificial Intelligence (AI) in Photography. 

Artificial intelligence (AI) is now in common use in digital photography. One example of AI use is adding functionality to digital cameras including face, eye, and other subject recognition and tracking, scene recognition, and intelligent automatic cameras. AI is also used for post-processing images, including reducing noise, sharpening, digital enlargement and removing minor imperfections. Generative AI is being combined with digital photographic images to add, delete, replace or modify objects, to expand overly-cropped images, turn single images into panoramas, change the image background, or to change the style of a photographer’s images, blurring the line between photography and digital art. Dave’s presentation will discuss the main AI approach to image analysis and classification, Convolutional Neural Networks. He will also cover use of two generative AI approaches to image modification, Generative Adversarial Networks and Diffusion models, as well as AI-based defensive measures to combat uninvited image web-scraping for training sets. A number of examples will be used to illustrate these approaches.

Dave Anderson has a wide range of experience in photography, from film to digital imaging and uses both medium format and standard dSLRs. He has been a member of the Pagosa Springs Photography Club for several years.

The presentation will be followed by our monthly image share, for which Photography Club members may bring up to five images each to share and discuss. This meeting will also be available on Zoom. The Zoom link will be emailed to members; others who wish to attend may request the link by email to abutler@mac.com .

2D Photography-June Meeting

The June meeting of the Pagosa Springs Photography Club will be held on Wednesday June 12, at the Community United Methodist Church, 434 Lewis St. We will begin with social time at 6 pm, and the meeting will start at 6:30 pm. This month’s presentation will be by Joe Sinclair.  Joe will discuss techniques and tips for photographing flat subjects, or 2D Photography, such as documents or paintings. 

Joe Sinclair has been a member of the Pagosa Springs Photography Club for several years. In addition, he is a member of the Napa Valley Photographic Society in California. He has been photographing for 60 years with both film and digital cameras, and has received numerous awards for his photos. As photographers, it is often a challenge to represent our three dimensional world in a two dimensional photograph. However, in this presentation, Joe will discuss the challenge of accurately photographing two dimensional subjects. He will explore techniques and considerations for two-dimensional photography (photography of flat objects) that while simple to do are important to understand. The talk will then relate two-dimensional photography to normal photography, an understanding that is very useful for improving one’s skills as a photographer.

The presentation will be followed by our member’s image share. Photo Club members may bring up to five images to show and discuss with the group. Please bring these on a thumb drive. They should be saved as jpeg files of at least 2000 pixels on the long edge. 

This meeting will also be available on Zoom. The Zoom link will be emailed to members; others who wish to attend may request the link by email to abutler@mac.com .

Masking in Lightroom

The February meeting of the Pagosa Springs Photography Club will be held on Feb 14 at the Community United Methodist Church. Come at 6 PM for socializing; the presentation will begin at 6:30 PM. This month, we will have a presentation by Doug Coombs on Masking in Lightroom.

Lightroom (LR) introduced very powerful new masking tools in October of 2022. Learning to use these new tools is a game changer for photographers who are serious about post processing. Before this, LR had masking but it was not nearly as powerful as tools in Photoshop (PS). When you shoot a photo with your phone, the manufacturer’s software is using sophisticated algorithms to post-process it. If you shoot .jpg in your camera, your camera is doing the same. Ansel Adams was a master at post-processing in the darkroom and altered his original image greatly to take it beyond journalism to fine art. 

Moonrise Over Hernandez – Ansel Adams

See https://petapixel.com/2018/11/07/the-story-behind-ansel-adams-iconic-moonrise-hernandez/ for an article on Moonrise Over Hernandez, one of Ansel Adams’ most famous photos.

Today we can do much more, with more control and more options digitally, which has raised the bar considerably. People used to ask me if a photo was “photoshopped”, as if post-processing in Photoshop (PS) is somehow cheating. All fine art photos of all sorts have been post-processed from the beginning of photography, at least to adjust overall light balance, contrast and emphasis. LR and Adobe Camera Raw (ACR) use the same photo processing engine. LR is separate from PS and includes many photography-specific tools. PS incorporates ACR with many additional tools in PS itself, often used after post-processing in ACR. In terms of processing a raw photo, ACR and LR are basically equivalent. Doug will discuss the masking tool in LR and ACR from the LR perspective and then demonstrate how he has processed some photos using LR masking. It is not uncommon for him to use multiple masks in a photo. Each mask is considered a local adjustment and emphasizes some particular aspect of the photo. It could be an animal’s eye, head or portion of its body. It could be the sky, foreground or band of vegetation in a landscape. It could be part of a person’s face including eyes, lips, teeth, cheeks and more. Doug  will provide useful links from YouTube at his presentation.

Even if you don’t use LR or ACR, masking is a universal tool found in other post-processing software, so this presentation should be useful.

The photo of the eagle below, has four masks.

The naturescape below, has three masks.

This program will also be available via Zoom. Members will receive an email with the Zoom link, others may request it by email (abutler@mac.com).

Creative Use of Aperture and Depth of Field

The next meeting of the Pagosa Springs Photography Club will be held Sept 13 at the Community United Methodist Church on Lewis Street. Come at 6 pm to socialize with your fellow shutterbugs. The presentation will start at 6:30. The topic this month is Aperture and Depth of Field. We will watch and discuss a video on this subject by National Geographic photographer Joel Sartore. The video will discuss how to use aperture to create visual effects and control depth of field. When, and why might you want to use a shallow depth of field? What’s the effect of lens focal length on depth of field? What creative optical effects can you produce with either a low aperture such as f/2.8 or a high aperture like f/22? What is your experience? As Andy will be out of town, Vice President Gregg Heid will be hosting this meeting.

This will be a hybrid meeting. Those who can’t attend in person may request the Zoom link by email to abutler@mac.com. After the presentation, we will have a member’s image share. Please bring your images to share (up to 5 per photographer, jpeg format please) on a flash drive.
