Well there’s a bunch of entirely new features that make the 5D Mark III a SLR capable of in-camera High Dynamic Range shooting, with an expanded autobracketing options too (up to 7 frames covering a vast +/- 8 EV range). It can also record multiple exposures, if you so desire. The introduction of DIGIC 5+ means that JPEG processing includes chromatic aberration correction, based on lens profiles which are stored in-camera therefore it’s limited to Canon’s own lenses.
And last but not least, the multiple exposure setting, it’s great because you are able to combine two (or more) images in your DSLR. One is a base image, in this case a couple portrait; the second, “fill,” image, is a detail from the couples hands.
The camera’s multiple exposure mode did the work of merging the two frames, automatically filling the second, image into the base image. Aligning the images is easier when you work in live view. Like in film avoid overexposure, the best is that you don’t need to make the two shots at the same time. Save one to your memory card until you find its complement… for example in one day you decide to shot silhouettes and as long as you keep the raws in the memory card you can go another day/week/month shooting the filling image.
Another good feature is that you keep the original images and the resulting multiple exposure image. When you’ve found the fill image to place within the base image, you’re ready to make the composition. Go through your camera’s settings to find the multi-exposure mode. Select it and switch your camera to live view. The base image will be displayed on the LCD screen so that you easily can line up the images. The display in live view will show you the base image directly while you are seeing the result of overlay and when it fits well within the base image, fire away. Your camera will automatically merge the two.
Here some samples from the last couple shooting in the open air, the DSLR comes with a highly advanced autofocus system, so why on earth did I use manual focus lenses? Actually there are some very good reasons…
