I am away on holiday and have been importing the raw files from my Nikon D700 onto my iPad 1 so that I can look through them and upload some to Facebook etc. When I try to edit them in photoshop express the images appear in a really tiny size so that they are not possible to edit. I did google the problem and the only solution seemed to be that I should import them via iTunes which is not an option for me at this stage. I have been using snapseed instead which works perfectly. Any suggestions?
