Hi all, looking for a bit of advice really. I processed a batch of photos for a friend, I then loaded them all onto a memory stick for her to keep and print if need be. She has come back saying the "image sizes are small and if photos are blown up the quality wont be great". When I processed the pictures i didnt resize, compress or do anything to reduce their size other than tweaks with curves etc. I have had a look at the image size and some are 1.43mb (colour) and others smaller such as B&W's. Can anyone shed some light on this please? thank you kindly :thinking:
 
That seems like a very small file size considering a large fine JPEG out of a D300 is ~ 4-7 MB.

What did you process and save them with? How exactly did you save them?

Thanks Jim - I opened them in CS4 made the changes and then, file save as.
Not sure what ive done wrong !:(
 
Perhaps a silly question, but the camera isn't set to small or medium size JPG is it?
 
Aaagh - i remember this was the shoot where i somehow managed to flick from raw to jpeg settings without realising until i got home. I think i was trying to change my ISO (on top of D300 beside the Qual button). Oh no, is there anything I can do to sort it? Please tell me theres a way to increase the file size without affecting the quality??
 
If they were shot in small/medium jpg only there's not a lot you can do other than 'force' them up a bit in PS, if they're sharp and perfectly exposed you'd get away with a little bit of forcing. What size do they need to be printed at? if it's 5x7 or 6x4 or even 8x6 they should be ok.
 
Image > Image size > then increase the pixel or document size, select 'bicubic smoother' from the bottom dropdown (it suggests this for enlarging images, I'm not 100% sure if it is much better).
 
As a very rough guide:

Under 16x12 printers run at 300 DPI

This means each "inch" is 300 pixels.

6x4 print = 1800x1200 pixels (6*300 x 4*300)

Above 16x12, many printers seem to run 240 DPI. The same applies.

Obivously you don't need to print pixel-for-pixel and can often print larger, but use that as a general baseline.
