<p style="margin-left:40px;">10. Color fixers are different / the same as B&W fixers.
Fact: [...] Color fixers are usually pH 6 - 7 solutions of Ammonium Hypo with ammonium sulfite added for stability and sometimes they contain accelerators to assist in silver removal. Remember, in color, one roll of film is about equal to 3 rolls of B&W because of 3 layers, plus you are removing every bit of silver (you hope). Also, that silver is restrained by heavy doses of DIR coupler residues and other image enhancing chemicals. So.. you take a guess. Which is more complex? Color fixers are a bit more complex. A simple fix will work, but you have to leave the film in the fix about 2x longer to remove the silver halide. AND.. all color fixers are unhardened. So never use a hardened fixer or a strongly acid or basic fixer on color films unless you like to ruin your images or at least seriously disturb them.
Ich hoffe, das beantwortet die hier aufgeworfenen Fragen. Ich werde auch in Zukunft C41-Fixierer zum Fixieren von Farbfilmen nehmen, zumal ich ggü. SW-Fixierer keinen wirtschaftlichen Vorteil sehe. Aber natürlich kann jeder das so halten, wie er mag.
