Saving jpg options defaults

[meris]

When you save as jpg, you get this

 

Where does it choose initial values from? Sometimes I change these but generally they don't stick

 

And if I open a prev edited file I don't save as, how do I know what settings it will use?

NEVER use Progressive.  Ever.  Only Baseline Standard.

The Quality setting is a moot point.  You always change that setting to suit the particular photo you're saving, and the purpose for which you're saving it.  (You'll learn more about this in the Print Sharpening Class.)  So even if you can manage to get a default to stick, it won't matter, because you'll need to change it most times anyway.

This NEVER happens.  There is not a single circumstance where you would legitimately open a jpeg file then save it again as a jpeg file.  If you're doing this, something is wrong with your workflow.  Please elaborate on your situations so we can fix the problem.

It should save the same, only the last 2 options make the file smaller?

I edit in PS and save as jpg ~10mb. Because I don't want to keep as psd ~200mb or tiff (slow & ~100mb). I need jpg because if I use a viewer to look at photos it needs jpg. If I blogstomp it needs jpg. Proselect can take tiff but only 8bit.

Doesn't matter. Optimized and Progressive are unreliable, you can't be certain that every program will view them properly.  Standard is the only one to use, ever.  Size is irrelevant.

No no no no no no no no no no no no no.

ONLY save your master files as PSD, and ONLY use Bridge to view your files.

After the job is printed, paid and put to bed, you can convert your PSDs to jpegs for archiving.  But while the job is live, you MUST save PSDs.

what about layered tiffs?

what's the difference vs psd?

[Damien Symonds]

Tiffs are fine too, but they're just damned inconvenient.  Why scroll all the way down to "T" in the file format list when Adobe defaults to PSD every time? Save your time.
