Good evening. A few weeks ago I purchased the discounted bundle of Topaz' Gigapixel AI, DeNoise AI, and Topaz Sharpen AI. Someone posted a discount code on DPR, so I got an additional discount and got the bundle for about $85.

I admit that I am a resolution freak, and I also don't like looking at things that seem "soft", as that is never what I see when I look at something (so long as I have my glasses on). I never see a soft person, object, still life, or whatever. Call it a curse. I cannot appreciate soft images. Generally, I am an F8-F11 kinda guy. I know, I was probably dropped on my head as an infant. I also definitely don't like looking at pixellation, and I like my images large. I printed one 11x14 this year, one 13x19, and the rest were 35x40 or larger.

The camera I use is a Fuijifim GFX 100s, and I shoot full-size (11,648 x 8,736 files), using edited RAW files about half the time ad SOOC JPEGS about the other half the time. I like stuff sharp, large, and printed large.

Initially, in using Gigapixel AI, I was a little dismayed that the largest image files one can produce from it are 32,000 pixels per side. That is large enough for many things, but it is not large enough to cover a big wall without tiling. No matter, purchased as as part of a discounted bundle for $85, I use Gigapixel AI every day.

I found that for the quality of files I obtain from GFX 100s, image quality is sacrificed with Gigapixel AI. In at least one image, it seems to be adding pixel-level artifacts and notably decreasing contrast, but I basically paid $28 and some change when you divide the total bundle cost of $85 for the three Topaz programs by three. What I have decided to do with it regarding my GFX 100s files, is to basically not use it for those; if necessary, I will shoot vertical and stitch two or more files together for a larger image.

The image below is of a vineyard from above, take from a hot air balloon around 700' in altitude.

Below is a screenshot of part of the above image with a resolution-doubled Gigapixel AI version. The left side of the image is the GFX 100s file. The right side is of the same portion of the same image doubled in size with Gigapixel AI. You can see that the soil between the rows of vineyards is darker on the Fuji image, and brightened in the Gigapixel image, while the rows of vines are about the same brightness.

However it is reasonable to expect that Topaz may well improve their software with time. Even now, it is a bargain at the $28 or so I paid for it!

Here is the good part: I love old, mid-century advertising/art. What Gigapixel AI can achieve with some of the images I enlarged was a WONDERFUL surprise. It is EASY to blow the up to 300dpi, poster size images - that look good. If by any chance you love mid-century advertising, here are some examples of what you can get with Gigpixel AI:

This is an old Harley-Davidson flathead engine. I love 'em. The image on the left is the largest and best one that eons of stalking the Internet provided me. The one on the right is part of what was gleaned with Gigapixel AI.

The latter was enlarged to 9,840 x 12,804 pixels. None too shabby.

This is even better:

An old Peter Helck painting (I believe) used for early 1050's Chevrolet advertising. Here is what I found on the Internet; you see a zillion tiny dots related to printing technology of the time. Resolution is 1,223 x 729 pixels.

Here is the same image, enlarged on Gigapixel AI to 7,338 x 4,374 pixels. Most notably though, is the improved texture. The 1950's printing texture is gone! Instead, I got an image arguably more in line with that produced by the artist (at least texture-wise):

I have been having so much fun with Gigapixel AI that I have not even started to mess with DeNoise AI or Sharpen AI.

I hope this has been helpful.

Merry Christmas.

It would be helpful to point out that Gigapixel doesn't work on older computers? People all too often post about different App & plugins issues without stating what computer & OP they are using.

This is fascinating, It may help explain my unexpected experience with a single test of the software, I was thinking about initiating a thread about that result and ask others if there were flaws in my testing procedure.

I think I'll write it up and send it to you alone as a private message. Perhaps my mystery concerning this software can be resolved without opening it up to the entire DPR world.
 
With all due respect, I really cannot imagine the need to raise resolution on any 100 MP image any further. If that is necessary, there is something fundamentally wrong with that image, delete it and move on.

Yes, I should have mentioned which computers I was using.

I was unaware of problems with Gigapixel AI and older computers. When I first got Gigapixel, I was using my 2013 MacBook Pro with 16GB of RAM. It worked on that well enough, but was slow. Larger files, near the 32,000 pixel per side limit, would take more than half an hour to process.

I have since gotten a 2021 MacBook Pro with 64GB of RAM and it is several times faster. That said, I was using the new MacBook Pro and got a notification that I was out of application memory. I opened up the Activity Monitor and was surprised to see that Gigapixel AI was using 56GB of memory at the time.

I also recently bought the 3 software pack deal with additional discount. I dont really have a good need for gigapixel at the moment but i used to think that about denoise and sharpen tools as well.

I've only done some basic tests on high quality files and gigapixel doesnt really upscale any better than just resampling up in faststone.

I'm sure it will do better with low quality, low res files though.

Im really impressed with denoise and sharpen AI though, a new pc and tools is changing some of my processing workflow. What used to take 10 mins to export a file now takes 10 seconds..
 
You'll like Denoise ..

That is amazing! I am trying to clean up some 1980s photos. I assume you were using the latest version? I am still on Sierra and that wants High Sierra so I downloaded the older version.



Do more options open up when you buy the program?



Thanks!

Hi Diane. I did not ever use the trial version, so I am unsure about if I got more features by virtue of buying it. I bought it as part of the bundle with Denoise AI and Sharpen AI. I am using Mac's Monterey OS; I believe this is the latest version.

I have since continued to use GigaPixel AI and want to again stress the benefits of having tons of RAM. I was able to use it on my older 16GB of RAM laptop, but with some images, it will bog down my month-old MacBook Pro with 64GB of memory to the point that it will freeze and I have to force quit Gigapixel. Usually it is ok if I reduce the enlargement size and run it again. I really don't see why the max amount of RAM Apple offers should be marginal for single-image editing, in a computer supposedly intended for such, but with Gigapixel AI, it is.

I'm fairly certain all the Topaz trial versions are full versions, just time limited.

Kind of.

Trial versions add a watermark when exporting an edited image, and lack SaveAs option.

Gigapixel is great for improving noisy cellphone images, as in this quick shot that we would have missed if getting out a real camera. Filename says "very compressed 0.5x scale" (will not be visible after uploading). I could post the original, but take my word, it is awful.
