With RAW files and your primary editor (the one you get with Ctrl-E/Cmd-E and the one listed first in Lightroom's Preferences dialog under the "External Editing" tab), raw files are sent to Photoshop for rendering using Photoshop's own Camera Raw engine. There is no need for LR to create a copy, and the handoff is seamless and silent.
With anything other than a RAW file, you'll get the "Edit a Copy with Lightroom Adjustments"/"Edit a Copy"/"Edit Original" dialog box. Is that what you're seeing? Your question is a bit unclear, so if you can provide a clear example of what you are doing and how, we can quickly get to the bottom of this.
Hi Mike, thank you for the swift reply and sorry for my very late one. I have included a video so hopefully you can help me out here. I am having an issue because the file I am working with is a raw file in both cases as you will see. According to what you're saying I shouldn't get the pop up box in either case. Take a look and let me know what you think, thanks.
Considering the video that you shared, it would appear that in Photoshop CC you were possibly using an older version of Camera Raw that didn't support your camera. This could be the result of not updating, or it could be that you purchased a new camera that wasn't supported in Camera Raw running in Photoshop CC. Lightroom supported the camera, but Photoshop CC didn't for some reason.
The difference in Photoshop CC 2014 is that you are using a newer version of Camera Raw. And that version of Camera Raw is "in sync" with Lightroom. When Lightroom and Camera Raw are at the same level then you will be prompted as you were in Photoshop CC. It isn't necessary to create a copy first. Lightroom sends the raw image to Photoshop, and Photoshop CC 2014 will use Camera Raw to convert the image and then open it in Photoshop. The copy is created at the end of the Photoshop session.
There are many users who are using older versions of Photoshop or even companion editing programs from other companies. And the copy must be created first. But in your case where everything is current and synchronized, that copy doesn't have to be created first.
This would be different if you were editing a JPEG or TIF image. If you edit one of those formats using Photoshop you will always be given the choice that you are expecting.
Thanks Jim, I will try updating camera raw for the CC version and see if that fixes it.
I updated camera raw for CC and it is still different. I am at a loss for this.
