Image saving from RAW

Thanks for the clarification.

So you make extra edits to the rendered files in Photoshop, but don't save these edits into a layered or lossless file, you save direct to lossy JPG.

So as @D Fosse wrote, are you rendering as 16 or 8 BPC from the ACR workflow options into Photoshop? Additionally, if there are layers or alpha channels created by your edits, then these can cause issues for Save As to JPEG (unless you use legacy Save As or use Save a Copy).

Do you have legacy Save As set in preferences or are you using Save a Copy?

If I render/open multiple raw files to Photoshop from ACR, the first file I need to set as JPEG rather than PSD. Thereafter, JPEG is remembered in that session.

Screenshots illustrating the various dialogs would be helpful.

P.S. A more efficient option is to use Image Processor, Image Processor Pro or another script to use all open documents as the source and to save to JPEG at a given quality level and other options.

Thanks, I am aware of this but this isn't my problem. I've just made my issue a bit clearer I think below 🙂

let me try again........when I load multiple images into Camera Raw, I edit the images individually as appropriate. When I'm happy, I 'select all' and click open at the bottom right of the screen. This opens all the images as .CR2 files in photoshop. I make further edits in photoshop to each image and then want to save them as .jpgs individually. This part of the process used to remember that I want .jpg in the dropdown menu, a simple click to save then a dialogue box opened to ask what file size (1-12) I needed, also remembering the previous size. It then changed the open image to .jpg so that closing that image was a simple click on the 'x' at the top. The NEW way once all images are opened in Photoshop involves clicking save then changing the default .cr2 in the dropdown to .jpg, clicking save again, then to close the image, I have to click on the 'x' then confirm that I want to do that. 

It just adds time to my work-flow that I don't want and will give me a repetetive strain injury 🙂

You can save directly from ACR without rendering the raw images into Photoshop, here is an example using JPEG:

Sorry, but you need to be specific. What prompts?

By default, ACR now opens into Photoshop in 16 bit color depth (used to be 8). This excludes jpeg which doesn't support 16 bit depth. Is that what bothers you?
