Constant Light Versus Flash Light: Ep 234: Digital Photography 1 on 1
Mark is going on tour! Join him in a city near you: Phoenix, Seattle, LA, New York City, Dallas, Miami, Houston.

In this episode Mark walks through the differences between using constant light and light from a flash. Join Mark in the studio for a hands-on demonstration that shows how constant light produces different results than light coming from a flash.

    Thank you for this, Mark … coming from a video background, and just
    getting heavily into photography, I never understood what photogs meant by
    (and how) freezing motion with the same shutter speed. Now I do!

    One question though … with strobes, don’t they make strobes that have a
    light that is also always on so you are not working in the dark? Seems
    like it would help with setting up bounces, and such as well, no?

    one thing not address is the diffuser. the hot light COULD have one . I
    would say flashes are great for kid photography as they really dont like
    sitting still.

    Portability is a big factor.

    The models always look really awkward in the background.

    @barriospd you can normaly do the same things in this lessons with the
    cheaper (D7000/D5100 type) camera’s as with the D4/3s,x. They have just
    better quality and more buttons and advanced features.

    @barriospd There is not much that you can’t do with a simple DSLR that you
    can with a pro one.

    Always informative. Even though I feel comfortable with this material, i
    feel like i. Taking away more knowledge. Thanks, Mark!

    Everything he did in this video is easy to replicate using any digital
    camera that has manual settings. Any DSLR can easily duplicate Mark’s
    results as long as you understand how exposure works and how ISO, aperture,
    and shutter speed affect it. The only area one may have trouble with is
    remote flash triggering but even then there are low cost radio triggers
    such as Yongnuo RF 603’s or similar.

    Great video Mark. Couple of questions regarding the demo Quantum flash demo
    in the video: 1) Using a D90 body and 35mm DX lens, I tried recreating your
    demo with similar metering settings. However, I was unable to focus on my
    subject in the relative darkness; how did you achieve low-light focus at
    the settings specified? 2) If I understand correctly, you don’t need to
    worry about synch speed because of the fact that the only light is from the
    flash, and it has fast falloff, yes?

    @Kakkasaari but their would be some limitations to some and i would like to
    see him work with very limited resources and how he works through it or
    around them.

    Mark, what about fact that flash syncs only at 250 ? or i am confusing

    Why so we can all feel better with about our T3i’s and D3200’s ? The
    techniques dont change no matter what DSLR you have.

    For strobe flash work, is a light meter always needed? Thanks!

    Hey there, have you heard about “MagicSFXphoto” (do a Google search for
    it)? There you can watch a good free video explaining the right way to take
    awesome pictures. It made it easier for Daniel to take photographs which
    leave you with that wow-effect when you look at them. Hopefully it helps
    you as well…
