Though I don't find them very good at guessing the best model and settings automatically, and it's not always the model you'd expect to work best that actually does.The reason for that is the variety of image content and irregularities of lenses. TL DR #2 - If have a back-catalogue of JPEG images and own GigaPixel AI, you can use it to produce much better image quality from those JPEGs - including significantly reduced artefacts, "restored" detail, greater tonal adjustment latitude without banding etc. For one price, you get better JPEG conversion results plus an often-quite-capable (though not miracle-working and sometimes frustrating) resize tool. TL DR #1 - If you're thinking of buying JPEGtoRAW AI, buy GigaPixel AI instead. GigaPixel AI not only retains the detail, but actually improves on it.
I can get rid of the JPEG artefacts using Lightroom's luminance noise reduction slider, but it kills the detail. Not bad at all, IMHO This is not simply noise-reduction. on the right, the raw from GigaPixel, with a couple of minor additional adjustments in Lightroom after conversion:
Here's a 1:1 comparison - on the left, the JPEG. However, GigaPixel AI did a far better job. The resulting raw had way more and more-pronounced artefacts than the original JPEG image. One photo I had problems with in JPEGtoRAW was a moon-shot taken with my Panasonic DMC-FZ62 bridge camera.
If you do want to resize or enhance, then you can do that all-in-one step.Having played around with some of the same problematic JPEGs in GigaPixel AI using the "Low Resolution" model (which works best with JPEG compression artefacts) and x1.00 scale, I'm achieving much better results than I did in JPEGtoRAW AI, and with all of the benefits I'd originally hoped for. When saving, you will have the option to create the file as a DNG or TIFF for uncompressed editing capabilities. This will not upscale the image, and it will stay the same size. However, if the resolution or size is not an issue or should be kept the same, then you would want to use the "scale" model and use the "custom" option with an input of '1.' Gigapixel AI's other job is to resize and enhance low resolution images. Gigapixel AI can convert jpg or png files to DNGs or TIFFs. If anything, the current Gigapixel AI will be better quality as it has our new AI Engine in place. Restoring editing capabilities is referring to the function of converting a JPEG to a RAW image. To clarify, none of the capabilities would be lost by using Gigapixel AI instead of JPEGtoRAW AI. You can use a 1 to 1 ratio if you don't want to upscale, and this will still restore editing capabilities. The same functionality of JPEGtoRAW AI has been incorporated into Gigapixel AI's compression mode. I just wanted you to know that we've incorporated the majority of the features of JPEGtoRAW AI into Gigapixel AI.
