In the last movie, you saw how you can use a tilt-shift lens to greatly decrease depth of field.…We used it to create a toy effect.…You can also use it for more practical things.…You can use it for throwing backgrounds out very easily, to create really shallow depth of field effects.…We're going to do the opposite here.…We're going to use it to expand the depth of field.…Now, you can't use it to expand depth of field in just any situation, but you can in a situation…like this, where your camera is at an angle to your focal plane.…So take a look at what we have got here.…
If I look through my camera, I see that I have these two lenses.…This lens up here is out of focus and so is that one.…So I'm going to start by focusing my lens here, and I'm going to focus on this frontmost lens.…So, again, this is a tilt-shift lens, so it's manual. So I'm just working until that's in…focus. It looks like it is.…Now, look at the lens in the background, the long telephoto lens.…It's still out of focus.…I could possibly try to get it in focus through a depth of field--through an aperture change…
The course begins with a look at several common and inexpensive lens attachments, from polarizers to neutral density filters. The course then explores ultra-wide angle and fisheye lenses as well as ultra-long telephoto and macro lenses. The course concludes with a look at tilt-shift lenses, which are useful for architectural photography and special effects, and at offbeat lenses, such as Lensbaby and Holga attachments.
The course also contains Photoshop postproduction advice and examples that illustrate the creative possibilities that an expanded lens collection provides. And because some specialty lenses are extremely expensive, the course also contains advice on renting gear.
