I'm always impressed with your images Franz. I don't really know what they all are, but they are beautiful to look at anyway. I bet big prints would really look nice. :)

Franz: yes your DIC images are always excellent.
How do you get such a nice neutral background? When I try to get this type of detail on my Olympus DIC I have to slide the analyser such that the overall colour takes on a strong colour, anywhere from a red, yellow, green, blue.
A grey background usually shows little detail in such an image.

Thanks for the info. on diaphragms and refs. (on Mitch's post).

Thank you Mitch and NikonUser!

for NikonUser:
"How do you get such a nice neutral background? When I try to get this type of detail on my Olympus DIC I have to slide the analyser such that the overall colour takes on a strong colour, anywhere from a red, yellow, green, blue."
1. I put the DIC-prisma (analyser, over the objective) in a position where I have a neutral colour (not always possible).

2. The light for the exposure is coming from a flash, which is not automatic (not TTL). So I have to correct the light with neutral-filters. If the exposure is correct I have generally - not always - a grey background.

3. If the background is not a neutral grey I correct it when I make the conversion from the RAW-file to a JPG-file.
I do this with the Program from Pentax "Pentax Photo Laboratory". (I suppose you have something similar from Nikon).

Conclusion: To work with RAW-files for me is a necessary, big help (althoug I lose a lot of time).


Franz

Post Scriptum: I like very much your pictures!

I believe the polarizers add the green colour, I have seen the same effect in infinity Zeiss DIC.

HTH, Rene
