Science to the rescue! Saving the day on high ISO images

I’m not fond of processing all the photos I take. That could be why that up until 3 months ago, I had unprocessed folders of bird photos corresponding to trips going all the way back to 2014! Thousands of photos, taken and never processed, witting there waiting to see the light of day. In some ways it has been fun over the last 3 months, going through those photos, finding hidden treasures of things I don’t remember even taking. However, it’s also been a royal pain in the butt to slog through them all.

The light is at the end of the tunnel though! In another month, month and a half, I’ll have caught up! The last thing I thought I needed though was another step in the process of processing a RAW digital file into the final polished form. I try to keep my workflow very simple, with a basic RAW conversion and subsequent simple things in Photoshop (which typically for me is just some cropping if appropriate, and adding metadata about where the photo was taken). However there are always some photos that require a little bit more.

Photos that require “more” often include those taken in low light, whether it’s early in the morning, late in the evening, or due to cloudy or shady conditions. In those cases, to get enough shutter speed for me to hand-hold the camera (which I almost always do), you have to bump up the ISO setting. That does help getting a photo in low-light, but at the cost of a noisy image, and image that also seems to lack detail. Given how picky I am about my photos, I thus typically don’t shoot much in low light situations, unless it’s a rare bird or something else I really want to document.

Science to the rescue! Yesterday I was poking around Twitter, and came across someone posting a before-and-after of a really grainy, high ISO photo that had then been processed through “Topaz DeNoise AI” software. I’ve seen ads before for noise software like that. I have always been…skeptical…to say the least. What you see on those ads often seems too good to be true, turning a crappy, noisy picture into award winning material. But this wasn’t an ad from a company, it was a regular joe who was really pleased with the result and was sharing.

OK, I thought, what the hell, I’ll give it a whirl. I downloaded the software on a 30-day free trial, and was looking for an unprocessed, high-noise photo try it out with. Given my pool of unprocessed photos was much smaller than 3 months ago, I didn’t have much, but did have a photo of a Barred Owl from the state park across the street from just a few weeks ago. Barred Owls are quite rare in South Dakota, thus my using high-ISO in really bad lighting just to record the event.

I opened one of the owl photos in the software, and let it do it’s thing. Pardon the language but HOLY. CRAP. The software was showing a preview of the output at a 100% crop, showing the center of the image that was focused around the owl’s face. What was a recognizable, but noisy mess had been turned into something that was completely noise free. That part doesn’t shock me, as you can ALWAYS easily remove noise…but typically at a cost to image detail. Here, the opposite occurred, with feather detail around the face of the owl suddenly showing up, information content I thought didn’t even EXIST in the original image.

Topaz DeNoise AI software is something that may not only change how I process photos, it may change my birding habits themselves! I rarely go out with the camera is light is poor (which given our gloomy, often cloudy winters, is a lot!). I’m looking forward to experimenting with more high-ISO photos and seeing just what the DeNoise AI software can do! Even imagines with much more modest noise seem to get a nice “kick” in clarity and sharpness, more so than what I can typically get out of Photoshop. The only downside I’ve noticed is that depending on how aggressive you get with pushing the software, the image can start to turn into something that looks more like a painting than a photograph, but that’s just when I bump up the default “auto” settings where the software determines the appropriate level of correction, and instead push a maximally aggressive processing.

Cool software! Not an “ad” or anything for this software, as yesterday was the first day I even knew it existed, and I’m not getting reimbursed or anything for “endorsing” it with this post! Just passing along the info for photographers who want a potential solution to high ISO, noisy images.

Click on the image and look at full resolution to see exactly what the Topaz DeNoise AI software can do. A very noisy image, in both the background and the plumage on the owl’s face, is suddenly COMPLETELY noise free on the right, but what shocked me the most is the plumage detail that was ‘recovered’ by the software.
