Hi am having an issue with pic quality. it starts fine when I take the photo but once I have edited it in Photoshop the quality is not as good, to the point where if I try and print too large an image (even a4 size which should be OK) it comes out less sharp than before editing. What can I do? Would shooting in Raw help with this issue?
 
We really need to know a bit more about your workflow when editing and it would help if you could answer the following questions so we can hopefully pinpoint the issue(s):

Do you shoot in RAW or JPEG?
Do you save as a JPEG, PSD or TIFF?
Are you saving at 300dpi or 72? (if 72 this may be what is causing your prints to lose quality)
What sort of sharpening are you applying as this will have an impact on the final image. You might want to have a look at these two threads I wrote some time ago, they might help:

Sharpening - USM settings

High Pass Sharpening
 
Hi sorry a bit more detail. I shoot and save in JPEG (but can shoot in raw but have not yet tried).
As for dpi I have no idea. I have no option of either of those? How would I find out what I am saving it as?
 
Ok I click save as and I get file name / format i go for JPEG (no numbers or anything after it) / save in elements organiser is ticked and I leave it ticked / I don't save as a copy / ICC Profile is sRGB IEC61966-2.1 (no idea what this is but is always ticked (i could untick it if I want) / Thumbnail is ticked I cannot untick this that is not an option / Use lower case extension is ticked I can untick if I want.

That's all the details I have when I click save.
 
Open the folder that the image is saved in and right click the image and select properties then details. You should now have dimensions, dpi, image size and a host of other info.
 
Lets start from the beginning. What camera are you using? is it set to best quality? if its yes to the last and your using a decent camera then it should print an A4 size ok.
Next what are you actually doing to the pics? are you editing the pic and saving or editing and closing then reopening and doing more work later? the more times you save and close a jpeg the more it affects quality, try and do all your editing in one go, or if not save a PSD for the edits and reopen that one and then just convert to jpeg at the end.
Now the last bit, when you finish editing are you resizing for the A4? if not how are you getting it to the right size? if you are resizing how are you doing it?
Can you tell us the file size on an original image and the file size on one after you have edited it?
Theres so many variables we need more info to work out exactly what your doing.

Are you having several tries at "tweaking" your jpegs ? Each time you save in jpeg the file is compressed so you will lose some detail, the more you open and close the file, the worse the end product will be.
Save in .psd or .tiff then convert to jpeg if you wish to send it elsewhere (unless the person/place it is going can handle these formats).

Using RAW does have a psychological advantage too - when you first open it in Photoshop it always look worse than it would if you shot in jpeg, as no processing has been done in the camera. When you have finished doing what you have to do in Photoshop the end result always looks much better than when you imported it in RAW.
