wonderfull..!
did you need all the 150 photos?
-
Way to go! I'm also curious about your stacking method. Computer-controlled or manual? If manual, wow, that is a lot of effort.
-
Whatever the technical details, the result is phenomenal.
-
Fantastic.
(But I wonder how it would look with, say, image #131 omitted.) ;)
-
Simply beautiful, Bob, and well worth all the effort you put into it.
-
Fantastic.

I am sorry but I don't understand... image #131?
-
The main subject is not only wonderfully presented but the green leafy materials is nicely arranged.

If he blended 150 images, would it matter if just one was left out?
Say, number 131 (chosen at random) for instance.

Bob, this is just a question for you and anyone else viewing your image. When doing this style of photography, how important is a perfect specimen? I admit, I am going to try the technique you use next winter and I am going to use a perfect form of whatever I take a picture of image even if I have to do some doctoring of it. For me, imperfections in the flower detract from the image. I wonder what others think.

this is subjective.

so every image is a focal plane slice.. hence.. any omission produces out of focus results.

But if only one out of 150 is removed, I wonder if the lack of perfect focus is visible.

But if only one out of 150 is removed, I wonder if the lack of perfect focus is visible.
so I determine the number of image planes by trial and error since I don't know the lens depth of field or equivalently the width of the focal plane, the number of planes is approximate so in some cases removing a single plane may make no difference but in my setups they are determined by magnifying the resulting image and searching for out-of-focus areas. with flowers that are deep, you will be surprised to see just how many images are required to provide continuous sharpness. Consider the extent from one end of a flower to the base of visible stem at around 4 inches = 101.6 mm and suppose the depth of field for a particular lens at macro distances is around 1 mm, hence very quickly you get 102 images. If I was photographing a subject of reasonable flatness the number of image planes would decrease appreciably. Some of the large flowers like a Calla lily are six inches from the tip to base of the visible stem. I don't have any images saved where the number of images was not large enough to show you but you would see say in the stem regular periods of out-of-focus bands.
by the way, for high magnification using metallurgic microscope objectives the depth of field is on the order of microns. of course the image range extent for a bug is much less than the flower.
also it has happened more than once that I have actually printed one of these macro florals at say around 17x22 and have had my framer notice some out of focus areas... so to be on the safe side I do oversample.

Thanks for the excellent explanation, Bob.
