Are you talking about Photoshop Elements or Premiere Elements?
Photoshop Elements will certainly open it -- however you've posted your question to the Premiere Elements forum.
I'm talking about Photoshop Elements 11
Does it open RAW files from the Nikon D7100, because Photoshop Elements 9 does not.
I,ll post my question to the PE forum, sorry
Yes. Photoshop Elements 11 and Premiere Elements 11 should open your Nikon D7100 raw files if Camera Raw 7.4 is installed.
Raw images from Nikon D7100 are not supported until Photoshop Elements 11 and Premiere Elements 11.
Make sure that the Elements 11 version is updated for Camera Raw 7.4. See Help Menu/Updates.
If you are going to stay with your Photoshop Elements 9 Premiere Elements 9.0/9.0.1, you can use the DNG converter
to get .dng.
Remember, you need a version of Camera Raw that supports your camera as well as a version of Camera Raw that is suppported
by the version of Photoshop Elements Premiere Elements that you have.
