Well I was able to setup a legitimate stack today with my new linear stage

Ok so here's stack #2 with the linear stage. All in all, from beginning of the shoot to now, it has taken something like 8 hours of work. Long story short I bumped the setup ruining the stack so i had to start over, my batteries died in both my camera and my flashes so I had to wait for everything to charge mid-stack, stacking takes what has to be close to an hour since my laptop is so slow.... which I had to do three times because I tried to figure out how to make the hairs not have those odd artifacts which i could not undo so I had to start over again each time, and because finally when I had everything ok the computer froze and did not start to work again for another hour or so :shock:

UGH

SO, here's the final result. All in all, very minimal PP just cropping, rotating, RAW to jpeg conversion, and some curves.




60 images stacked, at increments of .05mm. The setup was a Pentax F 135mm F/2.8 with a reversed Pentax F 28mm F/2.8 stacked. The 135mm was wideopen and the 28mm was at I believe F/4. 3 second shutter speed, MLU, two flashes with their own respective diffusers, ISO 100.

What do you think of this one?

edit: some crops




The subject is a jumper I've had since it turned adult about a year ago. Its obviously dead now enabling me to do this

Looks about right depending on what you use for C. About 0.02mm is common.

I did some thinking about of diffraction softening and concluded that at high magnifications one should use low f-numbers. Say your lens is diffraction limited for normal photography at f* (like f:16 for example). Since the effect of diffraction is proportional to distance from the lens to the sensor the actual f-stop you use should never be higher than f*/(1+m).

This decreases the f-stop you should use for high magnifications, especially if you are stacking because you can tolerate small dof. Like if F*=f:16 and m=2 the actual f-stop you should dial in would be 16/(1+2) = 5.3

On the other hand the f-stop you use should never go lower than the optimum for your lens - often around f:5.6 - f:8.

Does this correlate with what you find in practice?
To be honest, I just shoot a couple test images and get a feel for each lens in multiple situations. I just draw from my own experiences and go from there. In essence though, yes that does correlate with what I find in practice. Hopefully some time in the near future I will have enough time to directly compare setups (i've been meaning to do a reversed 50mm shootout).

Thanks

Amazing work! Looks like you have found nice and sharp combo.
Nitrok, I'd say this is definitely my sharpest high-mag setup. Contrary to typical thinking, adding more glass between the subject and sensor has actually improved everything Im assuming the135mm telephoto acts as a correcting lens of sorts. Thanks by the way

Nice work for sure! how where you moving the camera at increments of .05mm?

just with your hand ? i have tried to stack about 60-70 Shoot as well only using my hands but im always getting to many error when stacking on the phidippus Hairs and other stuff.

You even attempted ~60 images stacked handheld??????? Holy crap!

any of the 4xx series work fine, as long as they have at least a 1" micrometer.
