    I have learned a lot from your vids. thank you!

    wow what an expert 🙂 he said that you need hold down shutter button in
    half way to change aperture 🙂 this is of course not truth. in Av mode to
    change aperture all you need to do is scroll fron whell… no need to hold
    shutter button. this functionality is so old as canon 300D

    well, to give him some credit, you do need to press the button halfway if
    your camera is “asleep” (which his was). but you think he’d realize he
    doesn’t need to keep it down.

  5. Phil Hamilton says:

    For those of you who criticize the video for saying to hold the shutter
    half way down when changing the aperture setting, he repeatedly said that
    he’s checking the exposure in the camera’s meter to make sure there’s
    enough light. You must hold the shutter half-way down to do this.

    lol if you don’t know what aperture is u shouldn’t have a 40d… why buy a
    semi pro DSLR as a beginner?

    This is youtube, anyone can make a video and act like a professional. This
    video should not be labeled as “Advanced Tips” as though coming from a pro.
    This video is a basic guide coming from a basic young photographer with
    basic knowledge.

  8. Mitchell Rosen says:

    aperture = how wide the hole of your lens is, measured in f/#’s or f-stops.
    a higher f/# means a smaller hole meaning less light gets in. a lower f/#
    means a larger hole meaning more light gets in. aperture affects depth of
    field, inversely. that is to say, a larger aperture results in a smaller
    depth of field. another way of thinking about it is: small number, small
    depth of field. large number, large depth of field fyi, depth of field is
    how much of the picture is in focus.

    I was recently ‘given’ this model camera from a friend after my Olympus
    packed up. I appreciate the tips !

  11. James de Boer says:

    yeah no doubt, on my rebel k2 you don’t need to hold it down in that mode

  12. Overhax says:

    nice video. (y)

  13. Green Plasticbag says:

    i still dont fully understand Aperture. the increasing and decreasing
    confuses me.

  14. iwishiwasadj says:

    im doing photography at college and just bought this camera, its got so
    much more than you need but is great value 😀

  15. Andresoioioi says:

    lol I really think that if you want to make a photography tutorial video
    you should think at least a little about how your framing your shoot…

  16. MantisDestroyer says:

    what should the aperture be for basic sunny outdoor? doing head shots
