Jpeg question re: quality loss

[shane1980]

Hi,


I shoot raw and convert my final images to jpg files what I want to know is, if I copy the file many times does it lose quality?

I don't use the save as option but merly just copy the file to a new folder also if I resize those copied jpegs is that regarded as editing and lose in quality

If any editing is done you are going to lose quality, if you just copy or cut from one folder and paste to another without going through a photo editor (Photoshop etc) then no quality will be lost as the data stays the same.

You will certainly lose quality if you resize, but not if you crop.

You will certainly lose quality if you resize, but not if you crop.

You will still lose quality by just the process of saving in jpg as it isn't a lossless format, each time you open in an editor and save you lose quality, even if nothing is done to the photo.

You will loose quality if the file is altered in any way and re-saved

I would just add that we are not talking huge losses if the jpg compression is set for best quality, but open and save enough an it will have an impact.

I guess my next question is,

I shoot raw and edit and save as tiff would I be better off staying with tiff and if I needed an image for print just convert to jpeg

Is it possible to save multiple images at once as tiffs with lightroom or photoshop

What's your normal workflow
Thanks

Import the RAW file into Lightroom, keep it there

Export, what you what, when you want in whatever format you want from Lightroom

Lightroom is "non-destructive", the original RAW file never gets changed, it just remembers your choices of settings applied to it

If your saving different edited versions? then use the tiff format.

why would you 'save' if no editing had taken place..?

I was just making the point that opening and saving will lose quality, not suggesting you should do so and lots of programs won't allow a save if nothing changed so it would be a save as. Wanted to help the OP understand that it wasn't editing that was the problem but saving from within an editor.
