HeliconFocus Macro Animation


Helicon
This animation shows 15 images (each focused at a different point) along with the composite image created by HeliconFocus.
 
How we took these images
To create the final composite image, we mounted our camera on a tripod and set the camera on MANUAL focus. We set our metering mode to APERTUE PRIORITY (Av or A on most cameras) and set the aperture to f8. We selected f8 because the widest opening on this lens was f2.8 and since most lenses take their sharpest images 3-stops down from wide open, f8 will yield very sharp results (Note the difference between "overall sharpness" and "depth of field - an image taken at f22 would have more depth of field but the entire image would be less sharp.  an image taken at f8 would have less depth of field, but what was in focus would be sharper than if it were taken at f22).

We then took 15 images - manually focusing at a slightly different point in the flower.

We then imported these images into Helicon Focus, clicked a button and a few seconds later, HeliconFocus had merged the sharpest portions of each image into a single sharp composite image.

One of the less obvious issues that HeliconFocus has to deal with (besides the magic of extracting the sharpest portions of each image) is that when you focus at a different points with a macro lens, the image size actually changes slightly (see the above animation). HeliconFocus handles this automatically as well.

Aside from close-ups, we use Helicon Focus for Landscape images when there is a very close object in the image.

We feel that Helicon Focus is one of the most amazing tools you can have in your digital photography arsenal!
