Choosing the Right Lens Length: Exploring Photography with Mark Wallace



Is there a difference between walking close to a subject to fill the frame or just zooming in with a longer lens? The short answer is yes. When we walk closer to our subject, things in the foreground become much larger than things in the background. Objects get larger (or smaller) disproportionately, this also creates “distortion.” On the other hand, when we zoom in, things all get larger (or smaller) in proportion to each other. And that long lens gives us something called “compression.”

These are seemingly complicated principles. In this episode, Mark Wallace uses everyday household items to demonstrate how everything works. Mark shows you how you can try this out at home and solidify all of these concepts.

  1. Hello Mark! I've just find your videos and they are amazing. I'm from Buenos Aires and I can't belive you're in Argentina!! It's the first time in my life (I think) that I'm watching a YouTube video in english from a guy that is in my city, so it has been a nice surprise
    Thank you for your videos, I'm lerning a lot
    Bye!!

  5. Forced perspective we used to use that in our underwater photography. Using a 16mm Nikonos lens and close focus on a setup on a coral wall with sea fans, sponges and various corals hanging out. Then have the camera pointed in an upward angle at the surface and hopefully the sun ball shining high in the sky. I would then have my model(my wife) swimming 15 feet about the scene. Made for a dramatic image. Oh, and the strobes would be pointed directly onto the close setup.

  12. Best teacher on photography on the internet 🙂!

    Also, impressed by your enthusiasm and willpower to continue to produce photography videos even during the lockdown !!

  15. Exaggerate the foreground – what you are demonstrating is the square part of the inverse square law. The inverse part relates to the amount of light available for your camera's exposure. The square part relates to the area of your field of view as function of distance.
    A simple data plot can illustrate how field of view as second degree function (i.e. distance squared) of distance changes enormously with shorter distances.
    It also shows that beyond a certain distance the effect is very small. Just like you can get a rather even flash exposure of a deep group with the flash at greater distance, or have little hope of a black background.
    If you relate this to the photo in the desert, look what happens when you crop the foreground away. The foreground effect is gone and you still have a very nice panorama-like landscape shot.
    Have you noticed, when you had gotten used to 35mm and moved to 24mm that you needed to get used to the wide angle and find perspective tricks to work around it? And then you took a 20mm and had to learn again. 🙂

  19. I can't imagine how oppressive & uncomfortable lock down must feel for you, Mark. As I understand it, you've been confined to hotel rooms basically since the start of the pandemic. It must be rough, but I'd just like to tell you your insight, skills, creativity, tutorials, wisdom, humour, and enthusiasm for photography has always been a positive contribution to the photographic community. I hope you can move around freely, soon.
    Take care, mate. 🙂

  21. HeyMark still locked up in BA. Not a bad place to be in. I too had a little apartment there for many years before retirement as an international consultant. Mine was is Santa Fe and Ascuenaga, close to the old Recoleta but it didn't look as nice as yours. Have you been to Caminito since your arrival there? Nice place for taking pictures. Also don't miss out on the opportunity to visit Montevideo and Colonia in Uruguay. In Colonia get yourself a model; it is worth it, it will remind you of the old towns in Spain.

  24. Never thought that the length of a lens would have an impact on perspective (when adjusting for framing). Focal length, yes, of course. But the length of a lens? That's really new to me (and everyone). Also, this only works with a Sony, right? Otherwise, why point out what camera is being used, right?
