Tilt-Shift Effect

Mon Mar 11, 2013 5:42 am

Just wanted to share something that I have been trying out lately with CS5. I dont have $2000 to buy a tilt shift lens but you can do the same effect with CS5 with some really cool and interesting results. Jut wondering if anyone has an actual tilt shift lens and how similar it is to the CS5 capability?

Heres a shot that I tried:

I can't help you with your Photoshop question, however; I can tell you this; not all "perspective control" (or PC) lenses are "tilt/shift"; Some are just "shift" lenses. I have a 35 mm Nikkor "shift" lens; First of all, you'll find that all PC lenses are manual focus, manual aperture; the ones that "shift" only are designed to reduce (or eliminate) the problem of anything (such tall buildings) which always seem to "come to a point at the top" anytime the optical axis of the lens is tilted up, to get the whole building in the frame; the front half of the lens is joined to the rear half by a dovetail mechanical connection; there is a large knob on the side, when turned, the front half of the lens starts "shifting" sideways, or "up"; at it's maximum "shift", the two halves of the lens "shift" 11 mm, however, the optical axis of both halves remain parallel to one another; a "tilt/shift lens also does this, however the front half of the lens ALSO "tilts" it's optical axis from side to side, ( in addition to being "shifted" from bottom to top. This movement on two axis is to give a small format camera the same "flexibility" of a large format view camera. Obviously, adding the movement in "tilt" greatly increases the mechanical complexity of the lens, (and also cause it to become much more expensive.)

Here's the "good news" about PC lenses in general; a lot of people buy them new, expecting all sorts of "miracles" from them; they really do things that can't be done with a regular lens, but because of their complexity, they can't be made to auto focus, and of course the aperture must be manually set as well; because of all this, a lot of people who buy them tend to seldom use them, and this causes many PC lenses to end up on places such as eBay, and many are still in "like new" condition. The one I have looks just as it did when it first came out of the box new, and still "works" like it did when it was new; ( and I didn't pay anything like $2,000 for it ! )

When I bought the thing, I was using it with my F5 film body; it gets very expensive "experimenting" when you have $15 to $18 tied up in every 36 exposures; obviously, it works exactly the same on a digital body, ( except for the crop-factor of a DX body) I use it much more now that I'm using a digital body most of the time. I use it mainly when photographing buildings, and interiors of buildings, and for this it works beautifully.

Have you or anybody else ever used the lens baby? If so, how is it?

I have two of the Nikon PC lenses and used to love them for the type work I do. The real tilt/shift camera was the 4X5 view camera. I used to use that as well but it had a 21" rail, plate film and was just to much to travel with. Canon has a wide PC lens, one whose character and performance I would like to See Nikon produce...(Yeah Right)...The Nikon PC lenses were originally designed in the days of film cameras and have not progressed any further to be anymore Digital compatible. They are not designed to be special effect lenses like fish-eyes, they just correct parallax issues.

Never used it, but I'll at least point out that Lensbaby's are not tilt/shift lenses. They're tilt lens with an emphasis on cost and ease of adjustment, not precision or optical quality.

I have on rare occasions seen some pretty good photos taken with Lensbabies...if the user knows what they're doing, they can make compelling photos with it. I've also seen a far larger number of mediocre photos taken with them and made worse than they would be with a normal lens because the depth of focus is shallow for no compositional reason, and often not aligned with the subject.

The real strength of a tilt-shift lens is not so much the ability to defocus areas. Even in the film days that could be achieved in the lab without Photoshop and without buying a $2000 lens. The real strength is the ability to correct for distortion and to align the plane of focus with planes of interest for depth of field you can't achieve with an ordinary lens and Photoshop.

I use one every now and then. I have the original Composer and I mainly use the double-glass optic on it.

I consider myself a very mediocre lensbaby user.   And the lensbaby effect, like the fisheye effect, can get very old, very soon. However, note that using it for a bit is a great way to become more confident about manual focusing, manual exposure, etc. If anyone is interested, drop me a note and I'll show you some shots I've shot with it.

This is almost true.   You are right that lensbabies have traditionally been selective focus lenses, not PC lenses (it's definitely the case for the optics that I use). However their latest optic, called Edge 80, is more like a PC lens. Here's a demo:

Unfortunately, at 80mm is kinda long and I think I'd prefer a wide angle PC lens instead of a short tele. But I recently read an article by a wedding photographer who loves their 90mm TS:

Samyang is about to release (mid-May I believe) a 24mm tilt-shift lens for the bargain price of.... $1,000!   Traditionally, Samyang lenses are considered quite sharp and great value but lack AF. Of course, no tilt-shift lens has AF so that is not an issue in this case.
