TrailCam, Edits and Experiments

It's been a tough winter for my trailcams. Two were killed by the December flooding. Two were stolen. Hundreds of dollars gone along with who knows how many images. Only one camera remains, and that one is at the back of my yard watching the entrance to the wetlands, which Montgomery County calls Central Perkiomen Park and I call Ground Level Tango aka GLT.

My role in these images is limited to the initial camera placement and settings, editing, and post-processing. The exposures are triggered by the camera's motion detector. The nighttime images (all but the dog walker and also the squirrel) are infrared. Since they all (day and night) appear to be at 1/30 second at f/2, there must be some automatic exposure adjustment. The relatively low clarity is, I believe, a factor of both that slow shutter speed and very strong compression. I suspect that the sensor does not have a very high native resolution and is instead providing a high pixel count through oversampling or upscaling, which is then compressed a lot to keep the file size down.

The keeper percentage is abysmally low. Many times I can find no reason what triggered the exposure. There are a lot of images of deer and fox butts, which nobody wants to see.

1. No special editing.
2. Colorized via PALETTE.FM. Unmesh did a video on this a while back, and his opinion was that this was the best colorization at the time. I have seen nothing to suggest that is not still true. Following Unmesh's process, it is still possible to do this for free, but you need to be careful since they now are a paid-for service.
3. This is a composite of six images taken on the same night.
4. This is also a composite. The color is via Photoshop's neural colorization filter. I removed the colorization from the foreground snow, which had turned the same color as the deer.
5. It appears that the light level was low enough to switch to B&W but high enough to not trigger the flash.
6. Flying Squirrel. For everyone of a certain age, his name will always be Rocky.

Sorry to hear about your trailcam issues. I was hoping after the flood loss things would get better for you. I like your colorizing in #2. That turned out nicely. The composite (#3) fooled me at first. All those critters hanging out together? Lol. I think it's a cool idea to composite those trail cam photos to show an evening's progress ... as for Rocky - Bullwinkle's perfect pronunciation of MonongaHEla and Youghiogheny still cracks me up when I think of it!
