Hi,


Anyone had any experience with this software?
It looks interesting, but I wanna know if it's for real.

Wow, this is very interesting. Wonder how it can fix a blurred jpg looking picture to that sharp.

A trail is available and I just tested it with one image.
It's very impressive  :o

Yes it is.  I've been rendering at 4K, 3840x2160, so to test, I rendered the same image in HD.  The HD version rendered in 47m 19s and the 4K one in 3h 00m 18s, so that's a huge time savings.  The quality level resizing up from HD to 4K appears identical.  Need to run a few tests on scenes that would tend to show changes due to resizing.

Forgot to check resource savings (difference between rendering in 4K and HD.)

This is just their Topaz clean feature employed with resizing.

Been using Topaz Labs for over a decade I think.

I honestly think you'd get better control using Topaz Labs for Photoshop itself? You can of course use PS batch features or scripts.

And my copy is like over a decade old and doesn't seem to be any different than their results with this "A.I." Gigaplex.

I'm really interested in the deep image neural network setups that I've been seeing going around. I can't seem to find the one from google, but found this other one I hadn't seen: https://dmitryulyanov.github.io/deep_image_prior

WAS... Where is the "clean" function in the Studio menu, or is it a paid plugin?

Yeah it's part of the Topaz Labs Suite for Photoshop. Forget which version (I think it's Topaz Labs 7; I don't currently have it installed cause all my backups are missing somewhere in this rig). Looking at their website, it seems in-fact, they removed Clean filter for use with this new system, which is odd.

Edit: Here are "classic" downloads: https://topazlabs.com/clean/

Edit 2: I often used clean in conjunction with denoise or dejpeg depending on the image. As for the actually rescaling, it's probably stepped like what's been discussed here at 10% intervals, or using the best enlargement algorithm as a base and just doing a full resize.

That's similar but it was a rather new post on showing some similar demonstrations at the Topaz, super low res images with fabrics and skin, etc.

Tried a quick test.  Rendered at 800x800 in TG, then resized in Affinity Photo, ON1 2019 RAW, and Topaz A.I Gigapixel to 3200x3200.  Then cropped to a 800x800 area. Images are, the original, resized x4 in Affinity, On1, and Topaz. [edit] Forgot to post these in jpg.... sorry Oshyan

Looks more like warpsharp-warpresizing like an old Gimp and Virtualdub plugin to me. But a little better version then those.

jaf

Yeah, but not bad if one had a limited machine or doesn't have the time to render at higher resolutions.

Yes.
I tried some variations in Virtualdub.Topaz does have a little more detail in general...from the tests i made at least.

I just never liked Topaz algorithms. They're very flat and artistic like. You can see it in the leaf textures and berries in the resized.

Never-mind the obvious jpeg noise I expect, but doing some testing, it seems you get more detail just using photoshop resizing with it's denoise and smart sharpen / sharpen filters.

To my eyes, it preserves texture detail better.
