Recently, I mentioned a few programs in a comment. Program relating to reducing noise in photographs.
It should go without saying that I have no financial, personal, or emotional investment or stake in any of these products. I own them all, but most have free trials for anyone interested.
This post aims for a quick comparison between the tools using this photo (as shot, no adjustments)
If you click on the photo, you’ll get a version that’s 1280-pixels-wide. If you click HERE, you get the full-size version (9MB, 5568 x 3712 pixels).
A 1280-pixels-wide crop would give you this . . .
Here I should mention that if you’re just going to show the uncropped version, noise is not going to be an issue. For instance, here’s the processing of that photo using my standard editing for showing it on the blog.
Since hardly anyone clicks on images or goes to SmugMug, That would be good enough because no one would see this:
The first line of noise reduction (if you have what I have) is Lightroom CC. It has a pretty good noise reduction function.
Oh, one more thing. When you do noise reduction, you can and often have an unwanted loss of resolution and detail. If I just removed the noise, this is what it would look like; as a reminder, the original:
At some point, I decide on a workable compromise. For instance:
My next step might be DxO PhotoLab . . .
. . . which, with its Prime setting, gets rid of a bit more noise. The sharpening function of PhotoLab is a subtle thing, so while there is an improvement, you really have to examine the photo, which most people don’t do.
My first choice is usually the Dfine 2 module in the Nik Collection. Here, I might get something like this:
Note: I go through some version of these processes because I like to pixel-peek, although I’m less anal these days and seldom try the impossible.
I have another tool . . . Topaz DeNoise AI. That program actually incorporates an earlier AI module called AI Clear in addition to the new DeNoise module.
DeNoise AI uses a different algorithm than AI Clear, but both are included and you can choose whichever you think does a better job.
You also have the option to use the “Auto” settings for each, or manually tweak the process. In the Auto mode, the program decides on the amount of noise reduction and sharpness to apply.
DeNoise AI (Auto Mode)
Here’s what it looks like on a 1280-pixels-wide crop.
AI Clear (Auto Mode)
Here, you see less of the funky patterning. Again, it’s a different option in the program and which one you use depends on the photo you are processing and what details it contains. For this photo, Clean AI does a better job (in my opinion). Here’s the 1280-pixels-wide crop.
The manual options for both modules give fairly similar results, but I still liked the AI Clear version better.
AI Clear (Manual Adjustments)
Mind you, I could take the above and sharpen it a tad in Lightroom, but I start introducing noise again. Sharpen AI occasionally performs magic . . .
Let me show the original for comparison . . .
A few more details, if you’ll pardon the pun . . . DxO PhotoLab and Nik Collection make use of “Control Points” to modify which part of the photo is affected by any adjustments you make. A guy Anthony Morganti has an excellent series of videos about the Nik Collection and every module in it.
Topaz and Lightroom both make use of “brushes” to paint (add or delete) from the mask used to make adjustments. You can find Topaz instruction videos both from official and aftermarket sources and Lightroom is no slouch in that department.
Finally, the reason for multiple tools (my reasons for multiple tools) is that any given tool works for some things and not for others. If you had to choose just one, I suggest taking advantage of the free trials and evaluating them on your own photos.
I hope this was useful to someone, but if not . . .
