Why have jpg2000

[BethGwinn]

I shot raw all the time.  I am 70 years old and I figure it can help me and it does.  But now I can not make a jpg off the raw image.  You have taken the jpg off the list.  So I have to make it a jpg2000 and then change it and then go back and take out the word copy.  My clients do not know what a jpg2000 is and it dosen't work on all platforms.  I want jpg back.

It sounds like your processed image does not fit all the requirements for using jpeg. That means, RGB, 8-bits/channel, no additional channels, background layer only (no extra layers or Layer 0), no additional channels over and above the three RGB channels.
Photoshop does let you use jpeg but it does this via the Save a Copy menu. When using Save a copy, the copy is flattened and the other items in the list changed to fit within the jpeg file format. The original though is still on your computer, giving you the choice to save the master file in a format that does support those extra items. It was done this way to avoid data loss by inadvertently saving into the jpeg format and losing the extra layers , channels, bit depth etc

@BethGwinn I agree with @davescm I'm guessing that your file is 16 bpc which is the "new" default workflow setting in ACR.

If you are not performing any editing in Photoshop and are simply rendering the raw files into Photoshop for saving as JPEG you can skip that step and process the raw files directly into JPEG from within ACR using the "save options" button at the top of the interface, which is the 3 sided box icon with the downward arrow.

Hang on a sec, Beth. JPEG, JPEG2000, and JPEG Stereo (whaaa?) are on the list of formats available when I use File>Save As -- as well as 13 other formats. Like Dave suggests, something's off with your RAW files. Which camera are they coming from, and are you opening the Raw files in another app before Photoshop?

If your file is 16 bpc, then this would be because you have Legacy Save As enabled in your File Handling Preferences/Settings.

Otherwise you would have to tick the box to save a copy to make JPEG available as a file format option from a 16 bpc original.

While on the topic of bit-depth, it should be noted that HDR 32 bpc requires tone mapping to 16 or 8 bpc, as this isn't "silently" performed in the background when using Save as it is with Export As.
