Also, many camera bodies prevent the full functionality of a perspective control lens, which requires spending even more money on a camera that does allow full functionality. The drawback of doing so is that the cost of that type of lens is relatively expensive. One solution is to use a perspective control lens. The drawback of doing so is that the maximum print size is reduced. One workaround is to move the camera farther away from the scene and to crop the image. In that situation, even though the distance from front to rear of the scene may be a few inches or centimeters, it may not be possible for everything in the frame to be in focus. Another common example is when close-up or macro photography is being done. One common example is when a landscape scene includes an object very near the camera and a mountain or horizon that is miles away. Please explain in more detail about when would you require focus bracketing.There are certain situations (scenes) when the lens being used does not allow you to have everything within the frame in focus. Perhaps some of you have thoughts about the process or results that I haven't considered and should take into account for the testing. If no one else has, I guess I'll need to take the time to do a through test to find out. I have tried it both ways (more commonly in producing a panorama than a focus stack) but not in a scientific controlled process so I've not been able to realistically compare the results. Perhaps it doesn't make any difference, but then again, there may be different results depending upon the sequence used. Are we better to do the focus stacking first for each of the three sets of exposure values, then blend the three merged focus stacked images, OR would we be better to merge the three matching exposures first, one set for each focal point, then focus stack the resultant three exposure stacked images? The second question concerns post processing. During shooting, are we better to use the camera's automated Exposure Bracketing OR Focus Bracketing and manually set the alternative to get the 9 source images? I have two questions for those of you that have played with this scenario. Either way, I would end up with nine images to be combined. I would either need to manually focus close, then mid range, then distant and take Bracketed Exposures at each focus point, OR, shoot Focus Bracketing at -2EV, 0EV, and 2EV. If I had a scene that was both high dynamic range and required more DoF than my f-stop provides, I could get both the short focus stack and the bracketed exposure sets of images but if I am going to combine them into a single image, I could only benefit from one kind of automated bracketing. My Canon SX50 can do Exposure Bracketing and (short stack) Focus Bracketing but not at the same time.
