JPG after edit vs RAW file size

1 year 2 months ago #749064 by Sean Lamber
Let's see if I can explain this and make sense.  Now I normally will shoot in RAW, then I edit files in Photoshop or Lightroom (preferred).  One thing just became a little more aware of is just how small my JPG files are after editing.  Usually the seem to be under 5MB or less (mostly less).  When editing a 36MP (for example) files, what size should the JPG be afterwards?

I quickly tested some old RAW files on Photoshop.

Small RAW files of 11-13mb
transferred to jpg 6-7mb
This is full size (12, not compressed) Baseline Standard jpg's

G'day Sean

Yes - the JPGs will be smaller than RAW or TIFF -- but remember that the algorithm is designed to return your image "to as close as possible" to its original state when viewed / printed later on

I shoot JPG exclusively and regularly print to 8" x 12" thru to 24" wide as needed by the subject. Viewers of these prints (spread around the house) have never commented that they can detect any issues with sharpness or clarity via my use of JPG

Hope this helps

But doesn't it depend on what software you are using during the editing process?

G'day Karen

To some extent, it's a 'yes' with a -but- after it
Once you have finished working (playing) with the RAW file and you decide to save it to JPG, that part of the process asks you "what JPG quality do you want"

I use PS Elements and it offers me 12 levels of "quality" along the slider bar in the Save script.  I also have some much older (Windows-95 capable) software that simply asks "Hi-Med-Lo"

Obviously the higher the quality you select, the larger will be the resulting file once it has been saved

Hope this helps
