Focus Stacking Experiment
Dec 4, 2014 11:53:46 #
I took a typical Focus Chart and did a series of shots at 45* from top to bottom focusing on each horizontal line.
12 shots at 6mm increments included in the Stack using the Zerene Stacker.
I did PP in Topaz Detail3 to sharpen the Details, bring out some Exposure & Contrast and zeroed out the saturation to eliminate the Chromatic Aberrations of the lens.

Looks good to me, CraigFair. I've got to try out this technique. I've had Helicon Focus since the first of the year and have never even tried it.

This is a good example of stacking. I have 'Combine ZP', which is a 'stand alone' layer stack software. Like Dixiegirl, I have not tried my stacking program either. Shame on us, lol.

Thank you Dixiegirl & DOOK. It's been fun. I'm close but a little fuzzy between the lines.
Next I'll try shooting twice as many for the stack at 3mm increments. Or move up 1 f/stop if I feel lazy.:P

Decreased the spacing to 3mm and I'm pleased not ecstatic but pleased. I am horrified at the Aberration in this lens. I've heard such good things about Canon Lenses.
The DoF Chart says I should use 2.1mm but I have no way of measuring that.
Oh I could, maybe another time. The horizontal lines are spaced at 6mm.

Craig, by aberration, are you talking about halos or shadows around the edges? If that's the case, and I'm not familiar with Zerene, but Helicon says the aberration is caused by the stacking program itself not the lens. Helicon provides a tool for 'cleaning up' any aberration. I have the Canon 100 macro and have never noticed aberration or any other problem with it.

Hi Dixie, If you look at pic #2, closeup of the 4, and hit 'Download and the + to blow it up you will see the Red on one side and Blue on the other sides of the 3,4 and 5. That is exactly what I was seeing through the camera 'Live View'. I believe the previous owner of the Lens most likely dropped or banged the Lens badly to cause such a problem that pronounced. Sorry to bash the lens without knowing any better. First Canon I've ever owned. Been a Nikon guy since the early 70's. I'm going to try the other Canon Lenses and see how they do. Thanks for letting know Canon does make good equipment.
I just tested the 18-55mm kit lens and the problem is still there but far, far less. I had too blow it up quite-a-bit to make it noticeable, very acceptable.
Is something is wrong with my 100mm Lens??? Or am I just pushing it too far???

Yes, I do see what you're talking about, Craig. Of course I don't know, but I would guess that there must be something wrong with your lens. Maybe it was the reason the lens was sold. No, I didn't think you were bashing Canon lenses at all, and in fact, I own the 18-55mm and have noticed aberration with it. That said, however, it's not uncommon to get some aberration with the wider angle lenses when shooting toward a light source. Don't give up on Canon. I have several Canon lenses and have had no problems with any other than the aberration I mentioned with the 18-55.

I have trouble lining up elements within one shot...trying multiple exposures melded into one would be ridiculous for me! Way beyond my technical "talents". I leave the tough stuff with you younger folks! You all amaze me!

Hi Bob, Thank you but I've seen plenty of your work and it is fabulous. I really like you resent 'Asian Pear Blossoms', Great bokeh, lighting, focus and composition. Real eye catching.
I'm adding a stacked shot of 12 exposures of the same 'Coaster'.
