    For me, a more practical everyday use of AI Gigapixel is with low resolution images. The downsized jpg images received from family members who then want it printed. Genuine Fractals was the first of this type of software, but it had limitations in how well it worked with random patterns in nature. AI Gigapixel does amazing things even with ripples in water. Now I have a tool that really works!

      That’s a good point. I haven’t tested it on such images and it’s making wonder how it would do with scans of old photos…

      I feel another test coming on!

    I agree 100% with your review, Andy, I use it on already high-resolution images from a Nikon D810 and 850 and the results are fantastic, especially on images larger than 36 x24 inches. I was asked to do a 60 x40 inch print and was gobsmacked at the detail and sharpness.

    • AndyBell

      I recently upsized an old EOS 300D (a 6mp camera) to do a 60×40 print. I didn’t think anything could manage that but A.I. Gigapixel produced a perfectly acceptable upscale.

      It’s astonishingly good…

    • AndyBell

      I know – it seems crazy. I can push old EOS 300D images to 60 inches! It shouldn’t be possible. But it is!

      Their new sharpening/unblur/focus correction tool is also great. I’ll be reviewing it soon…

      • Douglas Ritchie

        Thanks for your reply Andy, I also have been very surprised with Topaz Ai Sharp, again amazing results with no artifacts or haloing.

    It seems to me that a valuable application that you don’t mention is cropping to extend the reach of your lens.

    For example, rather than carry a zoom, you could use one of two fast primes or use one of the fine fixed-lens compacts.

    I suspect that cropping a prime lens image and enlarging with Gigapixel would give excellent results compared to a zoom while lightening your load – fast zooms are heavy buggers to lug around…

    • AndyBell

      That’s a good observation. Thankfully it’s easy to test as I can compare my 85mm prime with my 70-300 mm zoom at various focal lengths and see what the result is.

      Expect a new post soon…

    • AndyBell

      As far as I can tell the metadata problem occurred with Topaz Sharpen AI but not with Gigapixel AI. I don’t know if they’ve fixed Sharpen AI yet – it’s a great sharpening and deblurring tool but I haven’t got around to really testing it yet.

  10. I just purchased this software. I do composites using my images in Photoshop and save as a PSD. Have you had experience with composites having the same good results? I’m not sure it would make a difference.

    • AndyBell

      I don’t have experience of using it with composite images, but I can’t see why it wouldn’t work with them. You might need to convert the images to TIF files first – I’m not sure it will open PSD files.

    A few questions if I may please –
    My interest was piqued after viewing a video talk by Nick Knight on his exhibition of still life’s of roses which he shot on his iPhone and blew up to 5 or 6 feet !!!!
    He talked about using Topaz gigapixel and sharpen. But did say that there is a “texture”, unlike grain or pixelation, that goes with the territory. Can anyone elaborate on that?
    I’m also curious to know what the ‘order of operations’ is – do you first enlarge (gigapixel) and then sharpen (aisharpen) as you would conventionally?
    I usually shoot raw images and process them in ACR prior to saving as a Tif. In ACR I do some sharpening. Is it best to skip this sharpening altogether? If I need to resize (upscale) I do this in ACR too.

    • AndyBell


      Sometimes Sharpen, when correcting out of focus or motion blur, can leave a texture – this indicates that the settings are not optimal and you need to adjust them more. Of course, some images may be beyond repair and won’t ever look perfect. The texture occurs when Sharpen has tried to ‘line up’ pixels that are blurred but hasn’t quite achieved it.

      I’ve not seen texture with Gigapixel, not with sharp and detailed images in any case.

      My sharpening strategy is:

      A little touch during RAW processing in Luminar 4 or PhotoNinja

      Denoise AI if needed

      Sharpen AI after further tweaking of the image

      Maybe a little more sharpening after resizing, depending on how it looks.

      When upsizing Gigapixel provides that final sharpening. After downsizing a touch of extra sharpening can help if you are printing.
