Excellent question, David, but I haven't done enough tries yet to be able to give a good answer.

I do remember running Gigapixel on the entire file and going to take a nice nap while my computer cranked!

I shoot in RAW and convert the file to a DNG, and the goal would be to be able to just define the area of interest plus a bit more, and run Topaz just on that partial DNG without having to create a TIFF or JPEG file as an intermediate image. And then crop that for composition.

If you follow Topaz's recommended approach, Gigapixel gives great results.

1. Run Denoise AI
2. Run Sharpen AI
3. THEN run Gigapixel on the image.

I've had excellent results on astrophotography images.

I doubt Gigapixel can actually 'add detail back' to your images BUT it really does appear to on occasions.

I have used it quite successfully. I do not believe that it adds detail into the image but changes "things" so that there is little or no loss upon enlargement.

If you use other Topaz software, use DeNoise first and then any others but use Gigapixel AI last. Good luck!

Very helpful process. Thanks!

I’ve used On1 Resize with great results.

I'm a long time proponent of Qimage, and use it for every image I print (including those from Gigapixel). As a printing utility, it can't be beat.

Has anyone used Gigapixel with an Intel I3 processor ? There web site says I5 or I7.

That is truly amazing . I see why you are exited about it. wow !

It is really good and worth it!!!

Last year, I compared ON1 resize to Gigapixel AI, and I thought ON1 Resize was the winner.
But this year, with the newest releases of Gigapixel AI, this is no longer true. Gigapixel AI is the clear winner.

In other testing I have done, I have used DxO DeepPrime on the RAW file and then used Gigapixel AI. And so far this is the best I have seen.

Regarding the comments about not getting more detail than was in the original image. Its not the right question. There is usually more detail in the RAW file than you actually see. The act of demosaicing is not an exact science and can reduce detail and add artifacts. There are multitudes of different demosaicing algorithms available. In fact, RawTherapee has 10 or so versions you can choose from. And some are better than others. And if you only shoot JPEGs, you get the demosaicing algorithm the camera manufacturer decided to use. Recently, with DxO's latest release, they introduced DeepPrime. They also tweaked the demosaicing process. I am not sure whether they now use the new demosaicing algorithm for everything, or if it was needed for DeepPrime to work. So I have decided to start with DeepPrime, even when I don't have a noise problem, and then go to Gigapixel AI. And I can't find anything that beats this. Not even Adobe with its new Super Resolution, which by the way is not a name I would have called it since that name has already been used for taking multiple images and stacking them to increase detail, most commonly in Photoshop.

By the way, while using DxO for DeepPrime, I will add shapening if needed and possibly some micro contrast before handing it off to Gigapixel AI.

Also, let me say that Gigapixel AI is very computational intensive. Older computers and those with weaker GPUs may not be up to the task. There are lots of complaints that it is too slow on these older machines. And one way to know the GPU is not up to the task is to tell Gigapixel AI to not use it. If you have a fast GPU, the convert time will go up. If the GPU is underpowered, the convert time may actually go down with the CPU doing all the work. But an underpowered machine can take many minutes, perhaps more than 30 minutes to convert whereas a fast machine may do the conversion in a minute or less.

Adding a mono image using Gigapixel AI. I had taken a Sony A6300 and had the Color Filter Array stripped off converting it into a monochrome camera. As a monochrome, there is no demosaicing to do, thus it makes no sense to use DxO DeepPrime on the RAW file.

Using a Samyang 135mm f2 lens, I captured a shot of a small bird near by. I then resized it x6 using Gigapixel AI. Keep in mind that at 6x (which I also cropped heavy), the software is inventing new pixels to add to the image and working to make them make sense. It is using Artificial Intelligence to do this. In fact, at 6x, it is inventing 35 new pixels for every 1 existing pixel. This is beyond using algorithms to figure out the new pixels.

First image is the original. Note how tiny the bird is.

Second image is the 6x resized version with heavy cropping.

This is probably more extreme than one would normally push it, but I wanted to push it on this one. I can see a bit of halo around the beak and I probably could back of on sharpening and make that go away.

Another Gigapixel AI example. Used a Nikon P1000 for this and also used a RAW file.

First image is the original.

Second image is the 2x resized image. I did not use DxO DeepPrime on this since at the time of this image, DeepPrime was not yet released.

At 2x, Gigapixel AI is only inventing 3 new pixels for every one existing pixel.

Hi, I'm in the same boat trying to find the best SW product for this. I have purchased Topaz and I think I may have to go to the GigapixelAI version. I'm also using Luminar. Would you mind sharing the discount code with me? Thanks,
