Green scan @ Fstop 7 (same as above)

Purple scan @ Fstop 14


The green looks Great! However I see the trade off between focus/depth of field and smoothness. I too wish someone from David would chine in on this topic, but it seems that no matter how many times it has been brought up here no one from the company has offered any advise or explanation.

Thanks.

I got even better (I hope)

I did the following adjustments as per this thread

viewtopic.php?f=15&t=6045&p=29377&hilit=50+hz+magic#p29377

Set my Canon camera as NTSC
Frame rate 15 FPS
ISO 400
F14
Shutter 30

I hope this will be repeatable

Also, I changed from vertical to both in the "orientation" of the structured light (54 patterns)

Calibration panel 30 mm positive

Same setting as above.

Strips are back !

A real sync solutions is a MUST

Again, I spoke to soon.

My frame rate setting was off.

With the following settings (for this macro scan), strips are gone

FPS 29.970
Shutter 1/30 360 degree
F 16
ISO 85

Since I don't have that kind of control with my camera I tried changing the settings on the projector side. however the Optoma ML550 doesn't give you any adjustment there either accept for some very general gain, hue and some "flutter" compensation. The only thing I could try was changing the settings on the video card in win7. I tried all the frame rates from 85fps down to 40fps with 85fps seeming to give the best result. However the improvement was so subtle that it may have actually been just perception based on the color that David assigned to the scan when it was added to the shape fusion list. If numerical analysis showed no actual improvement I would believe it. I have a fried with a Canon D60 that he has said I could borrow so later this week I hope to try that along with Magic Lantern.

I find MagicLantern fantastic. I used it extensively when transferring old 8 mm film to HD video, also in regards to frequency problems.

An incredible free add-on the Canon DSLR cameras.

Nevertheless, your friend should read a little about it, since it does do some modification to the camera (reversible). I wouldn't want you to lose a friend :shock:

I found a setting that gives good results (Canon 60D live view, Magiclantern add-on FPS 15).

I noticed that I have waves again when I increase the brightness of the projector (Acer K135). It needs to stay below a certain level.

P.S. Trying to do like Maestro Mendez :wink:

All this is very new to me. I have the impression of doing a crash course thought.

This one is not coated.

The gorilla in the Lets Scan thread is painted grey with a normal mat can spray. I thought it was a little thick so I removed as much as possible before it dried.

The koala is already a mat grey pastic, so no coating.

Also no coating for the Bodum knife holder.

How are your scan coming along with your Canon?
