Tilt-shift lenses are expensive, niche optical instruments, and as such, it can be a bit difficult to tell if you really need one or not. This quick and useful video will show you if you need one or if you can just stick to Photoshop for the times you want that effect.
Coming to you from David Bergman of Adorama, this helpful video talks about tilt-shift effects and corrections and if you're better off buying a dedicated lens or simply creating them in post. While the tilt effect is often used to create miniature scenes, the other thing to note is that the tilt function can be also used to tilt the focal plane in a way that increases the depth of field for a given aperture. In addition, while all tilt-shift lenses are manual focus, they tend to be razor sharp and thus make excellent portraiture or landscape lenses, particularly if you're using them on a mirrorless camera with focus aids. I still use an old Canon TS-E 90mm f/2.8, and it makes for a relatively cheap, very high quality portraiture lens, with the added benefit of the tilt and shift functions. Check out the video above for the full rundown.
