Discarding jpegs due to multiple edits?

I'm still new to Photoshop Elements and just realized (after re-editing most of my jpgs) that you should save to psd, unless you're going to email your images. After having used Picassa (happily) for several years, I don't understand or like the PS filing system! Am I missing something? Why does every image that you edit, have to go into your computer's file....over and over....and......

My question was/is sincere. I use Zoner Studio software & indeed it does let me save an initial jpeg to a tiff file which I can then edit, and save as a jpeg again. That never occurred to me. I guess now I am wondering if I would lose more data by going from jpeg to tiff to jpeg over just one edit in jpeg?

While storage is relatively cheap, I have over 25,000 pictures (and counting) so I can't imagine saving them all as tiff or tiff+jpeg.

However, I will certainly give serious thought to converting some especially important ones to tiff for archival & temporary editing purposes.

Sorry if I misunderstood your original rather (to me) cryptic response.

I believe Zoner Photo Studio in the develop mode is like Lightroom in that you can use it in a non-destructive manner (this is default for LR I do not know if it must be selected as an option in Zoner). By that I mean it opens the file and applies your edits from a saved location without actually changing the original file. So even if you later adjust the edits, it applies them to the original untouched file resulting in minimal degradation when you export to a new file.

I wish I had learned this when I first started shooting digital. If you want to shoot JPEG, then get in the habit of saving as a TIFF every single time you edit.

On high quality JPEGs, loss of quality is visible after three saves in areas of fine detail, by my personal tests. These results are obviously exaggerated, but if there is a constant degradation, why do it?

I haven’t personally experimented with JPEG to TIFF conversion, but in theory, I think it should be lossless.

I agree, with Andy, about saving JPEGS as TIFF files, TIFF files can be quite large, after saving from JPEG, so you might want to pick the images you save, instead of saving in batches.
I actually, save as TIFF, before I start editing.
Depending on your editing/post processing skills, and the software you use, you might be amazed at the results of editing, even the worst over processed images.
Thanks

I have a a external hard drive that I save all my pictures AS TAKEN by date (190404 year month day) This allows me to have all my pictures to do as I see fit years after they were taken as well as a complete back up

What!!! I understand the toast and even the butter, but why raspberry jam (RA) on both pieces?!?!? One of them should have been juicy orange marmalade (JOM)! Eating in both RA and JOM provides more options when post processing sipping your coffee! Unless you don't (shudder) drink coffee after your breakfast!

I try only to edit a JPEG file once and will edit a JPEG if it is the only file that I have

The TIFF file routine is one way...---

But the way I understand jpeg files work...
Simply opening them, and closing them is no loss.
Loss comes after repeatedly "saving"...
So then, to edit, open the original, make a copy, and close the original.
Edit away on the copy, save it once, and done.
To tell the difference, the copy will usually be saved with a (-2) after the original file name.

DanielB is correct. The easiest way to edit JPEGs and protect yourself from degrading the image, it will degrade if you make a lot of changes, is to start with a duplicate JPEG. Save the original JPEG, and if you make to many edits to the duplicate simply erase it and start over with a second duplicate image.


Or, if you don't want to have to start over from scratch, do your editing nondestructively on layers, which means you must save it as a TIFF or PSD file, and you can go back and change the editing without starting over with everything.

Although it's preferable to do your editing on the RAW image, (if you shoot raw), but just as a point of interest, and to answer your query I have done considerable editing on jpg's, then having them printed, some as large as 24 x20, with no obvious degradation. I ran a test once, editing, saving, editing, saving, etc. multiple times and the 'loss' was minimal (to the eye). Each to his own I guess.

PLEASE, I DO NOT WANT A RAW VRS JPEG DISCUSSION. I have seen enough of those. You don't like jpeg, fine. But this is NOT the thread to explain to me and others why we should avoid jpeg.

My question is about real world experiences of those WHO DO USE JPEG in the area of degradation. I am asking if jpeg users have ever had to discard formerly good photos because they saw too much degradation after multiple edits. If so, how many edits? Were they saved at highest quality or compressed more each time?

Yes compression degrades - of that there is NO question. each time you save a file it compresses more. If editing JPG files, always create a copy first and do NOT save anything to the original file name. Then you can always go back to the straight out of camera version.

Saving your edited file as a TIF (non-compressed) will allow you to always go back and edit the same file without compression loss. You then have the original JPG and the ever-editable TIF

Thanks. That's been my limited experience with jpeg files edited up to 3-4 times.

Yes, that's true for recent versions. While I subscribe to Zoner Studio X, I still use version 17 which doesn't. I disable backups & only work on original jpegs because of storage concerns. I simply find Zoner X too confusing & much more than I need. Version 17 is less cluttered, simpler & easier for me to use.

But thank you for reminding me I always have the option to switch to version X if I want to avoid jpeg data loss.
