I have an etsy shop and do photoshopping, digital painting and so on.
I've got a commission from America to convert a 100 year old photo into black and white and then to digitally painting it in a semi impressionistic painting to be made into a poster and/or canvas of 20x30".
The scanned photo sent to me had a pixel count of about 230x150. I need a minimum of 4000x4000 to convert to colour and to paint and a printer will need this plus 300dpi to make into a poster. So as it stands it's mission impossible. I explained this and he has taken the image to a photo lab who've said they can't do much better but can provide a better scan of the photo and sharpen it a little.
I have suggested I use high pixel count images for the background using composite photos, like a patchwork and work in the main figures somehow. I've done a small section of the trees, which if you enlarge will see it has an impressionist effect, but the foliage is too vibrant for an impressionist painting. I've tried desaturating but this makes it look greyish whiten I need light and airiness.
Any suggestions on how I can achieve a lightness in this image? In fact any suggestions at all!
