Here is my Rube Goldberg stacking stage. It is built on a ball bearing pillow block (2200lb capacity) on a 1" ground steel rod balanced on the other side with a bearing rolling support. Step size per the micrometer gradations is 200 micro inch (5 microns). A fairly heavy cross slide vise adds mass a...

I'm going to need a finer lead screw to get below 1 mil steps. It looks like Lightroom manual purple defringing of 10, 41/63 or purple Lum -49, Sat -51 do a fair job of reducing the purple on this particular image. I think in this case the purple fringe adjustment works a bit better than the Lum/Sat...

This information may be around somewhere but I didn't find it with a search. I have recently acquired the Nikon MRL00102 and am trying to use it with a Nikkor 200mm, f4 lens. So far I'm not too impressed with my results. There seems to be a lot of purple fringing and the stack I've tried so far didn...

Hi,

I would like to configure the flash to take two shots in rapid sequence with the A flash firing for the first and the B flash for the second.

I'm not sure the controls can support this type of operation. Any other ways to do this other than building my own flash controls?

Thanks.

If you want to try it for another couple hours you can get Focus Projects for free.

Just got it but haven't tried it yet myself.

Yup, that's it.

I found this flower I haven't seen before down in my forest (Oregon Coastal Range). I tried searching a wildflower guide but must not know the right terms to use well enough. The flower itself is about 1/4". Slightly cropped 1x MP-E on 1.6x crop sensor. https://live.staticflickr.com/65535/2669866672...

Looks like a Picasso painting. Would be nice to see it posted bigger.

I found this eye to be interesting. The clear surface is quite smooth and glossy, though at 5x this shows a little abrasion. 59 images, 50D, MP-E, 5x, f4, Xerene, Pmax. https://farm2.staticflickr.com/1450/26006128563_cb6fa0f9a5_b.jpg 2016-04-23-02.34.00 ZS PMax_002-3196 by dbur971 , on Flickr and a ...

I just realized I think you can just start the stack again and it will pick up where it left off (so long as you don't disturb anything) for another 100 images. It might be a special situation where you want that many images with this lens. Too bad the MP-E does not have autofocus (or any focus for ...

Does the interface at least provide some method of previewing the limits, so you can iterate to set the center and count? There is no means to do that I can see. I think this works OK for up to 100 images in a stack. You could do 200 by specifying 100 in front and 100 behind the starting focus poin...

ML now has you set how many images ahead of the initial focus and how many after as well as the step size (1-10 of unknown units). It computes how many images that is and runs it. There is only setting the initial focus position now. It's simpler to me than the old method, though the actual step siz...
