    in settings, photos & camera, keep normal photo
    Save the normally exposed photo in addition to the HDR version.

    I've had this switched on. I offloaded my photos using image capture. I only see one copy of each picture in JPG format.

    What am I missing? Where is the HDR version?

    It stores both the HDR and normal version of the photo (for the life of me, I can't figure out why anyone would want to keep a lower resolution version also)

    So if I'm copying the files to my mac, where is the HDR version? image capture only sees/gets a jpg. should I see two files for each image? what is the file extension for HDR?

    thanks

    edit:

    So it DOES have duplicates of MOST pictures.

    Here's what I did:

    'keep photo' option is on.
    imported to mac with image capture.
    pictures were deleted from iPhone. do not show up in recent.
    on mac iphoto, imported the same pictures.
    they slowly started showing back up in recent photo stream on phone.

    There are two copies of most pictures, but not all. Both JPGs, sequentially numbered (IMG_0039.jpg, IMG_0040.jpg with second one being HDR).

    On iPhone screen the HDR has 'HDR' in corner. It does look better in most cases.

    Questions:

    1. Why do ALL photos not have an HDR counterpart?
    2. It seems unnecessary to 'keep original photo' if the better HDR is kept. this could get messy having two copies of everything.

    thoughts?

    High Dynamic Range combines three photos taken as fast as the camera can expose them (one under exp., one normal, and one over exp.). If you are shooting action, there may be ghosting. The normal version is the AE exposure (based on THE SINGLE SHOT auto-exposure). keeping the normal version may be beneficial for some situations.
