Ah yes, thanks. I do believe it is Xtol. Thanks for the links!

EDIT: It says not to increase any time and I can not find within that chart how long for 120 format films. I presume going by the darkroom's chart will be fine. Thanks for the help!

Xtol is an excellent developer. It is one of those for which Kodak give slightly different times for 35 mm and 120 - look in the 'Format' column in the small tank development table (Table 1). It's no big deal - individual variances from the careful processing that Kodak do for their exhaustive tests will usually account for more adjustments than the 35 mm - 120 difference.

I usually use it 1+3. This unofficial Xtol site has the Kodak times for the higher dilutions (1+2, 1+3, 1+5) that are no longer published by Kodak USA.

Good luck,
Helen

The darkroom suggests diluting it 1+1. I developed the FP4 125 (120 roll) at 9.5 minutes. I developed a couple rolls of FP4 125 (35mm) that I ran through the Holga as and a few that I ran through my 35mm camera at about 9 minutes as it was warmer. The pictures came out great, albeit a little dark. Nothing that can't be fixed. Thanks again for the help!
