We've been having tulips in the house lately, my favorite flower. So I've spent some time doing stack focus pictures with varying degrees of success and failure and frustration. Images with a greater range of color seems easier to do than ones with little color variation. Thus the one you are about to see worked while stacking images of a yellow rose has not been successful so far. I started with a series of images taken with the camera on a tripod to insure easier stacking. Here is an example of that series:
As you can see, the stem is in focus but not much else. The remaining images all had different focus points. By stacking, aligning, and blending the images, and then cropping, I was able to arrive at this:
By doing this, I am able to show texture in the petals, color at the center, and texture and color of the center flower parts. It is a striking photo when blown up and placed on a wall.
Hope you enjoy it!
