RA-4 Filtrations for Meopta filters
Arthur Brainville (Ybalrid)
- 2 minutes read - 295 wordsThese numbers are in the Meopta filter scale. The meopta color 3 user manual has a conversion table to other filters in case you want to cross reference my numbers.
There are acceptable starting filtration from one sample from what we batch of film I bought, onto whatever RA-4 paper I was able to buy.
It’s likely that all the paper is Fujicolor.
All RA-4 processing has been done at 35°C, in a kit from Bellini.
I make 1L of developer that I do not replenish, I reuse and reuse and reuse up until it craps out.
ADOX Color Mission Glossy
nota: probably a FUJICOLOR Crystal Archive (the lower end version) paper but does not have branding on the back?
Unless I precise something, the film was shot in the kind of light it’s designed to use
| Film stock | Cyan | Magenta | Yellow |
|---|---|---|---|
| Kodak Pro Image 100 | 0 | 90 | 90 |
| Lomography Metropolis | 0 | 95 | 90 |
| Kodak ColorPlus | 0 | 100 | 90 |
| Fujicolor Superia X-Tra 400 | 0 | 90 | 90 |
| REFLX LAB 800T (shot with various indor LED lights - none of the pictures on that roll were shot under correct tungsten lights…) | 0 | 65 | 75 |
| ORiginal WOlfen NC 500 (shot indoor under too warm of a light) | 0 | 90 | 100 |
Other papers (Probably either Fujicolor Crystal Archive Supreme, maybe DP II)
These are from old disorganized notes for last year.

| Fujicolor Superia X-Tra 400 | 0 | 80 | 70 |
| Kodak Gold | 0 | 75 | 75 or 60 |
| Lomography CN 800 (indoors cool) | 0 | 80 | 100 |
| Kodak Ultra Max (indoors warm) | 0 | 75 | 90 |
I have more prints of more interesting film stocks (ORWO NC500, Phoenix 200) that I may have the numbers written in my notebook, or at the back of them. I will complete these
