    Post Aspect Ratio/Image Size

    There are a couple of parameters we are all kind of stuck with BEFORE you crop. They are “aspect ratio” and “image size.”

    Image Size” determines the number of pixels that used in the creation of the image by the sensor. You cannot tell the difference between the three available (JPG) levels (S, M, L) on the Camera’s LCD display, but only on a much larger CRT/LCD (usually the computer), when you magnify.

    Aspect Ratio” refers to the two different formats now available in modern DLSRs, which is 3:2 (Standard) or 16:9 (HDTV). Basically, the 16:9 format simply reduces the top and bottom of the frame by eliminating its use on the sensor. The sensor does not get longer.

    8” X 10” prints do not comply with the 3:2 ratio. It actually winds up being 10” x 6.667” or 12” x 8” … so you can see you need consider more top and bottom area in the frame, if you are cropping to an 8 x 10 film standard. The more advanced “electronic image” frames automatically resize the image (proportionally) to display it, so there is not much of a struggle to make it work. The problem occurs with hard printing images.

    Look, I did not create the optical laws of the Universe ... I simply learned to deal with them.
    Remember: It is usually the GLASS, not the camera (except for moving to Full Frame), that gives you the most improvement in your photography.

    No ... it's in the Manual, just that way (A700 - page 94).

    [Aspect Ratio]: [16:9]
    L:10M . . . . . . . 4272 x 2400 pixels
    L:5.4M . . . . . . 3104 x 1744 pixels
    L:2.6M . . . . . . 2128 x 1200 pixels


    And referenced in a chart on this page, about 1/3 of the way down

    Okay ... I misunderstood ... I meant HDTV ... fair enough? Correction has been made.

    Thank you for picking that up, 'VR' ... don't want to confuse the masses.

    This is one of the few cameras with an HDMI terminal built into it.
