If this course is your first foray into real macro shooting, then you might find yourself…surprised at just how shallow the depth of field is in a macro shot.…When you are into a macro distance and your lens is open all the way, depth of field is…often measured in fractions of a millimeter.…Now this can cause a tremendous lost of detail across the surface of your subject especially…if your subject has any depth.…As you saw in the last movie, with the lens reversed, the camera has lost its ability…to tell the lens to close down to a particular aperture, which means you're stuck shooting wide open, …which means you'll have the least depth of field possible with that lens.…
Now if you're using an older lens, you may have an actual aperture ring on the lens.…This lets you set the aperture anywhere you want just by turning the ring.…Your meter should still work, because as the iris is closing, the amount of light passing…through the lens is diminishing and that's reflected in your meter reading.…
In this course, photographer Ben Long details the tools and techniques of lens-reversal macro photography. After investigating reversal ring options, the course explores the focusing and exposure techniques involved when shooting with a reversed lens.
