More DRR images

Here is a wider view of the 3D printed ABS honeycomb I had previously done with RGY at 10x. This time, it is GMB (green, magenta, blue) at 5x. It is just an average stack of two frames with the D3300, reduced here to 20% size.

It is nice to have more field for some objects!

Did you just print the filters on a transparent, or did you need to reprint it 2-3 times on the same slide to reach those rich colors?
I tried it to, but i found the colors rather "pale".

Great question. Almost all of the images I've posted have come from filters that were cut out of shim stock of different thicknesses (they are color coded), which have good saturation. Theater gels should work great, too. Whatever you use, it has to be really pretty thin, at least to go between the BD illuminator and objective nosepiece.

One case where I used a laser printed mask is shown on page 1 of this thread, just under the image of the 3x3 mask image. That was done with two transparencies stacked. In fact, looking at it, what it is has two different filter combos. Blue and cyan, green and yellow, and red and magenta were paired up. The overall effect was RGB. That is how I got rich colors for that image - it wasn't Photoshopped to improve saturation.

I'm glad you are trying! I've got an article coming Nov. 13th on Micscape that hopefully gives a more coherent explanation of the technique.

I ordered myself some cheap colored flash gels to experiment with.
It's fun is creating them yourself.
