    So I went to a photo place today and asked them for Digital Gray Cards, and he said they've got a pack of 3. I purchased them then left. When I opened them, they are regular gray cards. I think I read somewhere that film camera's generally use 18% gray and digital is usually between 30-37%. Will the standard gray card be fine? Or did I just waste money on the wrong thing?

    Every source i've seen, including books specifically about dslr photography says to use 18%. :dunno:

    All material I've read says that 18% grey is standard. Also in my 40D manual.

    I've actually never used a gray card, so it will be new to me. My teacher just recommended we get them, so I did. But if no one knows anything else about digital gray cards, then I guess it's not so bad that I've got standard gray cards.

    I use it probably 90% of the time when I'm out shooting.

    thats what you want, just make sure to angle it properly and have it lit by the same lighting as the subject.

    and make sure you know how to read your histogram properly

    Why fix a fuck up when you can get it right the first time?

    ansel adams didn't have lightroom :mamoru:


    overexpose a sunlit image by 2 stops, "fix" and see what happens
    underexpose a night image by 2 stops, "fix" and see what happens



    then come post again

    I'd say you get a better images from negative than a digital file. With digital comes noise. And if you're missing an exposure by that much, your fucking retarded.

    A lot of Ansel's stuff was post processed...in the darkroom. amirite? :eek3: I've been studying, professor.

    18% is standard for both film, and digi, but the cards for digital cameras differ in how they reflect light, thus getting it right the first time on the digital camera, where as a standard card will make your settings a little off on a digi camera. When shooting digital, it is better to have a digital card, though it is still 18% grey, and vice versa.

    I use gray cards for exposure readings(when not using flash) as well as a color calibration tool. Anytime I can miminalize PP, I'll go for it.


    I love being a pussy.

    My next tool I'd like to purchase is an incident light meter.

    Why does everyone always say this? As if a gray card can't be used with raw files? In fact that's when it should be used. Snap one quick pic of the gray card before you shoot, then sync the white balance of all your raw files with the shot of the gray card in post. 3 clicks and 5 seconds in Lightroom. Way more accurate than the camera's auto white balance, or trying to guess at a gray point in post.
