This setting removes Face Detection from the camera’s metering system. In scenes without detected human faces, by default, the camera will put focus points on the nearest subject with detail to the lens. If a human face is identified, the camera will put active AF points upon it - even if it’s not the nearest subject in the scene. (Default setting) EOS iTR AF (Face priority)Ĭolor metering, with the ability to read subject color and detect human faces that are within the area covered by the 45 AF points.The EOS 90D’s Custom Functions menu gives photographers three ways to work, when all AF points are active with Automatic AF point selection (also Zone AF and Large Zone AF): What we’re saying is that Face Detect AF, using the EOS 90D, has the potential to be more effective for through-the-viewfinder shooting than on any previous EOS digital SLR camera. The smaller APS-C size image sensor in the 90D is actually a benefit here, because AF points can extend further toward the edges of their total covered image area in the viewfinder. However, because they are full-frame cameras, their AF point coverage for viewfinder shooting doesn’t cover as much of the frame as the 45-point AF system in the EOS 90D. It minimizes the problem of the camera inadvertently focusing on a distant background instead of a human subject, and perhaps even more important, is a great aid to ensure sharp focus actually falls upon a face - and not part of a subject’s clothes, or an accessory like a hat a that a subject may be wearing.įace Detect AF is a capability that Canon DSLRs have had before, but until now, it was limited to full-frame cameras like the EOS 5D Mark IV and EOS-1D X Mark II. This can be a remarkable way to quickly put focus on faces, without taking the time to manually move an AF point or a zone of points from one part of the frame to another. For our discussion, however, we want to turn to its ability to read actual subject and scene information, and provide that info to the EOS 90D’s 45-point AF system. This same RGB metering sensor does an excellent job of exposure control, and reads and controls E-TTL flash exposure as well.
#Canon camera with viewfinder skin#
It can read color information, and now has sufficient pixel resolution to recognize human faces - not just skin tones - when viewing and composing through the viewfinder. With 220,000 pixels, the metering system can do far more than simply measure brightness. (The previous EOS 80D model had a much simpler RGB light metering sensor, with 7,560 pixels.) Think of this light metering sensor as a tiny “imaging sensor,” obviously much smaller and with far fewer pixels than today’s high-res image sensors. The metering sensor is now a 220,000 pixel RGB sensor, located near the viewfinder in the prism area of the camera. Canon engineers have stepped-up the EOS 90D’s basic exposure metering system, and this plays a major role in its AF capabilities with Face Detection as well.
