I was hoping I could scan them and then use gigapixel to create some new pixels that would let me blow them up in size without losing too much detail(I know it can't create new detail, but hopefully it can retain the detail that is there!) I have been considering gigapixel because I have a lot of old contact prints of family members that are only 2x3 inches or thereabouts. Around her mouth and nose and in the grasses.

While further processing in LR or any other post-processor will be materially slower due to the size of the output image (a TIFF that is almost 0.5 gigs), if sharpening is required (either for a print, saving an image where focus was missed, etc) I think Gigapixel AI is certainly worth the US$100. Note the grass shoots in the shadow to the left of the lioness! It may not be that apparent on Flickr, but there was a vast improvement in resolution. So the After image is 21,300 pixels per side or almost 455 mpx. Using LR I created a TIFF, processed it using Gigapixel AI as a LR extension setting the parameters to create a 6x up-scaling of the image.

I threw away almost half of the pixels I captured. Since I was at the maximum of my lens the resultant image was too small so I cropped down to a square, 3550 pixels per side or 12.6mpx.

To test the sharpening possible by up-sizing an image I chose a shot of a lioness I took in Africa in 2017.
