I would really appreciate some advice on how best to 'enlarge' an image for printing in Photoshop (CS5) and where in the digital workflow this step is best placed.
For example, if I am looking for a 39 x 28" print and am starting from a RAW file, is it best to first enlarge to this size in PS, prior to making changes such as cropping etc and prior to 'saving' as a TIFF or other format? Or is it better to convert to TIFF, then enlarge, then crop? OR... does it make no difference if I were to crop the RAW, save as a TIFF, then enlarge to this size?
Am I right in assuming that the most effective method used to enlarge an image in PS, is the [Image/Image Size] menu option?
Can I realistically expect to get a print of this size to be 'sharp' from say a 16MB (NEF) RAW file?
Any help, advice or pointers would be really appreciated.
Cheers in advance,
