Comment on The Origin of ‘My bad’ by unclenicks

Growing up in the San Francisco-Bay Area, I remember hearing Golden State Warrior, Chris Mullin (circa 1990) say during a radio interview that Manute Bol had used the phrase during practices and games. The players were so amused by it that the entire team began using it, as well.

Why does she spin faster when you just look at her head!!! If you scroll so just her head is visable she spins super fast!!!

to all of you stupid morons who think this is wrong because “its against God’s will”, poof! this creature exists, so it obviously must not be. if it was, it never would have even worked out. so shut up already.

Comment on The Fish Highway — Rat Tubes for an Aquarium by Fish Tanks - Tropical Fish Forums

[…] Posted Today, 06:51 PM If you could in some way make an acrylic tank that is hard to scratch then you would have something amazing. As far as shape it’s all been done. Tanks conected by tubes to other tanks like a hamster cage. Open bottom fish tanks are awesome.look it up on YouTube. http://www.youtube.c…e=youtube_gdata http://www.youtube.c…e=youtube_gdata if you really want to make a splash in the hobby fixing the material we use to make tanks would be best. Glass is heavy and cracks acrylic is light very hard to crack but scratched. They are not perfect. http://seanbuckley.c…or-an-aquarium/ […]

I forgot to mention, click on my name to go to my website and you can find some images where I used large format perspective control for effect. However, I don’t attempt to distory reality. I do it to emphasize the depth of a scene, for example. A good example would be a picture in my large format color portfolio that was shot in the Smokey Mountains and has a round rock in the foreground. But that type of perspective control can only be achieved with a large format camera.

BTW, perspective is only controlled by camera position. Camera settings in no way alter perspective with the exception of large format cameras which can alter apparent perspective by independently adjusting the lens and film planes. In other words, you can see the exact same effect that can be achieved by exploiting perspective effects just by looking at a scene. The key is to use a wide-angle lens positioned close to the foreground object. But this has nothing to do with how it is captured (digital or film). Also, depth-of-field is a totally different issue and it has nothing to do with perspective. However, wide angle lenses have greater depth-of-field for any given f-stop. It’s good to have everything in sharp focus in a picture like this but it does not alter the apparent size relationships. You do not need any kind of camera to see these effects. You can see them with your un-aided eyes. The camera merely records the scene. The focal length of the lens merely crops the image area. Perspective is ONLY controlled by viewing (or camera) position and nothing else. Even some professional photographers don’t understand this very basic fact but once you understand the concept, you can exploit it for creative effects. I am a large format photographer and I constantly control perspective. I include my website address where you can see some examples of what I mean. But I do not use it to trick or distort a scene.

Actually, the effect you are talking about has nothing to do with digital cameras. It is simple perspective and it has been exploited with film cameras since the inception of photography. It also has nothing to do with aperture size or depth-of-field. (I’m a professional photographer, BTW). But you are partially correct. The normal way to distort perspective with a camera is to use a wide-angle lens positioned relatively close to the object that you want to make appear larger. Then anything behind it will appear smaller than relative to the closer object. Fishermen have been doing this forever whether they meant to or not. That’s because they often have someone shoot a picture of their fish while they are in the boat and a wide angle lens is used. The fisherman stretches his arm out so that the fish is much closer (relatively) to the camera than the fisherman is. Another classic version of this were all the pictures taken that made it look like a tourist held the Eiffel Tower in his or her hand. But, again, this has absolutley nothing to do with digital cameras, apertures, or depth-of-field. Those are totally unrelated factors. The exact same rules of perspective apply to all optical systems including cameras.
