So, since I had massive rejection on GigaPixel4x upscaled photos of Midjourney generated AI images, I compared different options and found Midjourney's own 2x upscaling to be the most natural looking.  I've been uploading the 2x Midjourney upscaled photos and are getting good acceptance rates on Adobe Stock these days, but my concern is 2x upscale may not be big enough for some buyers.  So, my current option is to have Midjourney 2x upscaled photos to 2x upscale on Gigapixel AI on standard setting.  It seems like the standard setting mostly just double pixel count without overly make the photos look artificial.  What's your best option in upscaling AI images?  Do you think 2x upscale is enough for long run?  I'm worried I may need to re-upload 2x upscaled photos in 4x upscale to increase sales for buyers who want more pixels.  I was thinking maybe the buyers will do own upscaling if they want to.  But 2x upscaled photos look the most natural without looking artificial.

Since you're one of the contributors with most sales here on the board I would suggest to track your sales (via google lens, etc.) and look up in which resolution the images are used. I currently upscale also 2x and with lower resolutions about 4096 x 2288 or even lower.
Can't imagine higher resolutions are used that much, so I would instead use the setting, which leads to the most high acceptance ratio.

My 2x upscale resolution is 2688 x 1792.  I did check the sales of 2x upscaled photos and 4x upscaled photos, but so far haven't seen any evidence of buyers avoiding 2x upscaled photos compared to 4x upscaled photos.  That's a good thing.

Left side is the Midjourney's own 2x upscale.  Right side is additional 2x upscale on GigaPixel AI.

The biggest problem is the hairline that looks unnatural.  Looks better left blur without additional 2x upscale on GigaPixel AI.  Sometimes, facial feature looks too defined unnaturally too.  So, I think I'll just upload 2x Midjourny upscale for anything with face.  If no face, I'll do additional 2x upscale on GigaPixel AI to get more resolution.

But I may do 4x upscale if I find 2x uplcaled photos not selling well in the future.

In future I will now submit portraits only with the minimum resolution. The upscalers are currently still too poor for portraits. I will keep the originals in case better upscalers will come onto the market.
Other content such as still lifes (spa, flowers, animals, etc.) I will continue to upscale, which works quite well.

So, thank you for finetuning mine settings!

You are welcome!!
