Secondly, thereвЂ™s a pretty large focus shift. Here, we can see a couple of interesting things.ДЇirstly, what appeared to be вЂњperfect focusвЂќ when we started the test is actually 1 AF Microadjustment until away (this is the value of the red line at f/2.8). They are both very close here (less than 1 AF Microadjustment until apart) so we can be very confident of the calibration result:Дual Pixel Raw вЂ“ Focus Shift in Aperture Sharpness with Reikan FoCal HereвЂ™s an example вЂ“ the pink area shows the result of the dual-pixel analysis, and the black line is the result of the FoCal analysis. This can be used in tandem with the вЂњnormalвЂќ FoCal analysis results in order to confirm validity of the suggested value.

The fully automatic test can use the dual-pixel information to determine the correct AF Microadjustment. ThereвЂ™s more details belowвЂ¦ Fully Auto Calibration We can use this information to improve confidence in microadjustment calibration results, to figure out calibration valuesВ from the AF Consistency test, and to determine focus shift in the Aperture Sharpness test. All this information from a single image file! Not only can we find out how far from вЂњperfect focusвЂќ any point is, but we can also find out which direction the focus is shifted in вЂ“ front or back. The Dual Pixel Raw files contain all the information necessary to determine the focus position at any point on the sensor.

Canon themselves have demonstrated a few tricks that can be performed with this extra information within their DPP software вЂ“ micro refocusing of images, shifting of bokeh and reduction of ghosting. With the addition of Dual Pixel Raw capability, Canon now allows the information from both halves of these pixels to be saved in the image files. However, up until this most recent camera the dual-pixel magic was kept solely inside the camera. The Dual Pixel system has been used on the sensors of the 7D Mark II, 80D, 1D X Mark II and now the 5D Mark IV.

By cutting each pixel in half and having the halves look in slightly different directions, the camera can determine how to quickly and accurately focus at almost any point on the sensor. Dual Pixel SensorВ Structure.Д¬anon introduced the first Dual Pixel sensor in the EOS 70D camera to bring an unprecedented autofocus system to the live view capability of this camera. The answer isвЂ¦ quite a lot! Image В© Canon Europe. Following on from our previous post on the subject, weвЂ™ve been investigating how these files can help with autofocus calibration and general camera analysis.

With the introduction of the EOS 5D Mark IV, Canon opened up some new possibilities for image processing with the introduction of Dual Pixel Raw files.
