2nd test | Sepia
Again, iPhoto (first image) deals with presets and is relatively easy to pull off. The B&W effect also has a vignetting option which helps, whereas Duotone does not. One nice feature is that it’s able to retain the settings from the previous edit, but it appears you can only add one “effect” with each edit. Unfortunately, you can see that the highlights are a bit blown out which makes the face not look so good. iPhoto gives you the ability to adjust the B&W filter pretty easily, but you can’t isolate areas like you can with some of the other filters, so I wasn’t able to hold the exposure in one area and not another. You can do it by going back to the exposure setting, but it’s a little cumbersome since it removes the sepia effect until you re-apply it so it’s difficult to see exactly how your edit will affect the final image. The Snapseed version (second image) has much more control so I was able to make sure the most important part of the image (the face) was well preserved. In some cases, I prefer crisper images, so I also tried another version in Snapseed (third image) where I didn’t do any of the Tilt-shift or grain effects, just for comparison. The downside here is, in Snapseed, vignetting is usually a part of another effect, so if you want to keep it relatively clean, there isn’t a real easy option to add just a vignette.
