Hi, I have a number of images that I would like to submit to agencies/photograph libraries as my first submission. Only recently, have I saved files as TIFFs or RAW, the majority are as 300 dpi JPEGs.
Can I generate a 48MB file from a JPEG file? If so, how would I do this either in Photoshop or would I need another program? Any detailed advice you could give me (I'm a bit of a techno-phobe) would be much appreciated.
Not sure if you have Alamy in mind but if so, I think you may have misunderstood their requirements.
48Mb does not refer to JPG file. It refers to an 8-bit TIF file. When you save that file at best quality JPG, you would get around 5 or 6Mb. Alamy accepts that JPG file. JPEG compresses the data so that 48Mb TIF file will be compressed when saved as JPG. Hope this helps.
BTW, with say a 6Mp file, you need to upsize to get 48Mb. You can now easily do this in PS CS3 in one go. There is little benefit to use Genuine Fractals or Qimage or Photozoom Pro since Photoshop's algorithm is now very good.
