Re: Diy pentamirror blueprint

The original purpose of tilt/shift was to maximize depth of focus, but this exercise is potentially more about retro gimmicky effects.

The classic reason for tilt-shift was a field of wildflowers with a mountain range in the background. Tilt the plane of focus so that the foreground flower closeup is in focus and the distant mountains in the top part of the frame. Other objects outside of that plane will be out of focus but it doesn't matter.

The original utility was to achieve deep depth of field through cheating by tilting the plane of focus. These lenses have shallow depth of field but when you stop down the aperture to increase the depth of field (making it darker with a smaller opening), then you get a nice sharp image foreground and background in focus in spite of the lens' natural shallow depth of field.

The gimmicky approach takes the opposite approach by emphasizing the weaknesses of the lens.
