Photography for Idiots

  • Hi,

    So can anybody link me to some good online tutorials or Youtube videos for the nuts and bolts of CSC/DSLR shooting?

    I've been taking pics for years with compacts and I think I've got a fairly good eye for photography so it's less about framing etc. and more about things like ISO, shutter speeds, aperture etc.

    Searching through the millions of Youtube videos on the subject it's hard to see the wood for the trees so any recommendations would be most welcome.

    Cheers.

  • So i want to preface this with, I am a novice, please disregard.

    Cameras record light hitting the camera sensor and forms images, to do so they use specific settings to create an exposure : iso, aperture and shutter speed.

    Iso = how sensitive the sensor in the camera is to the light

    Aperture = how much light hits the sensor

    Shutter speed = how long the shutter stays open to let light in.

    Creating a good image is as easy as balancing these three things depending on the scenario and the need.

    For example, if you wanted to freeze the subject in place so the subject is sharp and not super blurry? Maybe a kid running around? You will need a high shutter speed, but the higher the shutter speed the less light makes it to the sensitive. To counter act that you will need to either make the camera more sensitive to light or open up the aperture to let more light in making up for this loss of light.

    Trade offs:

    Keep in mind, the higher the ISO, the grainier the image. The larger the aperture the smaller the depth of field; which is usually pleasant in portraits but can cause issues with focus. If your shutter speed is too low any movement or shaking of the camera will cause noticeable blur.

    This is a really broad and simple look at the exposure triangle.

  • @daniel1981: I like the Digital Photography School as a free site http://digital-photography-school.com/ and the Improve Photography site and http://improvephotography.com/ with his podcast. Improve Photography also has pay classes for around $100 each.

  • Improve Photography has some decent information, but Jim is often wrong or unhelpful, especially on the podcast.

    I think a beginning photographer would probably be better served by Scott Kelby's three-part series: http://www.amazon.com/dp/0321678737/

  • Tony Northrups book is pretty decent.
  • @YoThatLimp: Another way to look at Aperture is that it's the size of the lense opening and the smaller the lense opening the greater the depth of field and the bigger the lense opening the lesser the depth of field will be.


  • The best resource of info I had when I was starting out was a site called 'Cambridge in Colour'

    It breaks down the concepts of aperture, iso and shutter speed etc. and even has great examples that show the effects of changing settings that switch when you hover your mouse over.
