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.

Thanks for your post and may God Bless you in these strange times.

Very helpful to this novice photographer, Mark. Thanks!

very effective way to explain and demonstrate perspective and compression

@aklivn49 4 года назад

GREAT explanation. BEST I've seen on RU-vid.

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 RU-vid 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!!

Very good description of compression and distortion and how to use them.

@iainmacdonald7034 4 года назад

Really helpful, Mark - thank you. You clarified a lot for me with this simple exercise. I thought I understood it before, but didn't really! Stay safe.

@gvasquez330 4 года назад

Always good information Mark. Stay Safe

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.

Thanks for the class Mark. Now I understand why my nose is so big when doing selfies with my iPhone... Its my wide angle front camera lens.

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.

I've been to those places in previous visits to Argentina and BA. But for now, I can't go anywhere except for the grocery store or down the street to pick food from a cafe. Travel is strictly forbidden, even inside the city.

@kisankumar-oe6to 3 года назад

Great knowledge

@pictureeyecandy 4 года назад

Great lesson Mark, compression? it's more like perceived "Compression" I know you know this but I guess this is the easiest way for someone to understand this if they are newer to photography.

@redwinmedia 4 года назад

I thought Bokeh, more specifically, relates to 'points' of light that are out of focus in the background. Not just out of focus backgrounds. (10:00)

@coolcat23 4 года назад

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?

@PrasadPalaniyandi 4 года назад

Subject -Camera distance decides the perspective ( compression ) not Lens / Focal length. If you shoot a far away subject with 20 mm and 100 mm lenses from same spot the angle of view will be different but perspective/compression will be same. If you crop 20 mm picture to match to 100 mm frame you will see both exhibits same perspective. Photographers stay far to get their preferred perspective and zoom into get the composition they want rather than using wide lens and crop.

@MarkWallaceVideos 4 года назад

When I say the length of the lens I mean focal length. It doesn't matter what camera you use. I always say what gear I'm using because people ask. A lot. :)

boa mark! good to know u're near in argentina, I like your style to teach! helped me a lot! u don't know rs kkk thanxs

@terrinewton39 4 года назад

Nice explanation. You really can’t even go outside for a walk? Is nothing open there?

@MarkWallaceVideos 4 года назад

I can go outside to get food. Only essential shops are open in Buenos Aires right now (May 28, 2020). We've been under strict quarantine since March 20.

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. :)
