Basically the source was too blurry for Topaz to reconstruct realistically. The third crop shows a failed reconstruction. Using this at maybe 1/2 or 1/4 strength would probably be optimal. The output from Topaz is oversharpened in my opinion. The next image shows what happens on an area that was fine in the before picture. Topaz took a blurry source and corrected it with natural looking detail. The original image is on the left and Topaz Sharpen AI on the right (stabilize mode at 50% with 25% noise reduction). Keep in mind if you are looking at this on a normal screen the crops would correspond to a 70+ inch print.įirst, lets look at the back left corner. These are taken on a Sony A7R IV body (61MP or an image size of 9504 x 6336). I’ll be showing you 100% crops from the areas marked in the below. There’s a lot of different options in Topaz and it doesn’t provide much guidance on how to set them, so basically I had to use trial and error to choose the parameters. So I downloaded the Sharpen AI program and ran it over the entire image. While it looks fine at web resolution, the image is too soft and I’d normally throw this out but thought I might be able to fix it with Topaz. I had one landscape photo which I took at f/4 by accident instead of f/11 resulting in way too shallow a depth-of-field and having parts of the background and foreground be too blurry and much softer than I would like. But in practice, I find that sometimes it’s like magic and other times it produces garbage. Luminar AI, Photoshop Neural filters) essentially work by artificially generating textures and image detail so in theory there’s no limit to how much they can sharpen, remove noise, or magnify the existing detail in a photo. Topaz and the other AI based filters (E.g. Recently I’ve been trying programs like Topaz AI to correct some issues in photos that I that I messed up technically.
