    D300 with raw files coming out at 2848x4288

    Output to jpg and print at costco as 4x6

    Costco has a little blurb saying:

    Digital pictures are taken in an aspect ratio of 4x5.3, so a small portion of the top and bottom will be lost with a 4x6 print.​

    My photos came out cropped...

    Here is the original from cam

    Why did costco crop my photo?

    Why can't I grasp this?

    2848x4288 is just a few pixels away from 4x6, so what are they talking about with they reference 4x5.3 and why was the photo cropped so much?
  2. My understanding is that Costco is a consumer processor and as such is most used to dealing with people with point and shoot camera which are mostly 4:5 ratio sensors/files, hence the comment about cropping. The Nikon DSLRs are 2:3 ration sensors.
    Your cropping issue is caused by printer set up. Generally all printers will crop a bit so as to account for a range of tolerances such as paper position, etc. Your image seems to have cropped from the left and top mostly, this is perfectly acceptable. Most cameras would not display what is cropped in they viewfinder as most viewfinders do not have 100% coverage and so "crop" anyway.
    Hope that assists....
