(Macro shots like this one are another area where the small amount of adjustment might prove useful.) The clip is a screenshot of a beta version of Canon's DPP software, showing the extent of the +/- adjustment available.ĭual Pixel Raw does come at a price, though the raw files saved in this mode are twice the size of normal, weighing in at a hefty ~72 MB each, and as far as we know can only be processed by an updated version of Digital Photo Professional.
The little video clip above gives you some idea of the magnitude of the effect. If the catchlights are crisp, people looking at the picture will feel that it's a "sharp photo".)Ĭanon 5D Mark IV Dual Pixel RAW Demonstrationġ,920 x 1,080, H.264, Progressive, 30 fps (The trick to having a portrait look sharp when the DOF is well under an inch is to make sure the catchlights in your subject's eyes are sharp. Think in terms of a photo where the model's eyelashes were in sharp focus, but the catchlight in her eye was soft that's what we're talking about. The application that most immediately came to mind would be a portrait shot captured with a very wide-aperture lens, where the plane of focus was just barely off.

But do see the full discussion below, to understand why Canon is being careful not to use the "f-word" -)Ī very small adjustment is possible after tripping the shutter That obviously begs the question of what's being adjusted, and as long as you promise not to tell anyone, we'll go ahead and say that it's focus.
Instead, they refer to it as a "micro adjustment". Alternately - or in combination with the focus tweak, if you prefer - you can make small changes in the bokeh or out of focus areas of the image, or you can reduce ghosting to a degree.Ĭanon was very careful not to use the word "focus" when describing Dual Pixel Raw to us, saying that they don't want people to get the idea that they can make significant post-focus adjustments in software. What it amounts to is the ability to shift the apparent focus very slightly after a picture has been taken. The Canon 5D Mark IV introduces a new technology called Dual Pixel Raw for the first time.
