Thank you for waiting

Since quite a long time, I found no time to go on with my experiments on color photography. But I have been busy taken pictures and developing and scanning and publishing at Flickr.

After trying Dignan 2-bath method for more than one year, tweaking here and there, developing at room temperature, I may now say that it is a very good idea but it also has disadvantages. The bath A doesn't last that long as the author desired and you have to live with some color shift to green in negatives, magenta in positive.

Last October I came to another approach by Bill Williams, that I tried to simplify creating a 2-solutions color developer, like used in commercial color kits. But I was not so sure whether this would not conduct me at the end to a standard color developer, like many other fans of color film photography do.

So, I prepared 500 ml of a standard color developer that I am using since more than a month (six rolls and still going). I am using the developer with a start temperature of 42ºC (I don't have a JOBO device) and until now the results are very good for me. The recipe may be found here, for instance.

Some results of using the standard color developer:

How long have you been using this CD4 developing agent? Is it any toxic? How do you handle it? Do you store it at your home? What precautios should anyone take with this? Seller says that you need to use minnimum a dust filter mask, do you use it?

I just avoid contact with skin (gloves) and respiratory system when using the powder. During use after diluted, no danger, thus I have no skin contact and it doesn't affect respiratory system.
