Bergger Versus Forte
I can not remember whether it was in this forum that
the question of whether these 200 speed films are the same was ask. Never the less I have done a side by side comparision, by my intial test it appears they are not. I shot both 120 rolls under identical conditions, controlled ambient daylight, metering from a centrally positioned grey card. Both films were processed using the Bergger suggested PMK time of 12 minutes, I processed both rolls in the same tank using 500ml of solution, dilution was 1+2+100 at 68F. I did add a pinch of amidol to increase the overall speed for both films. The end result, appears that Bergger produced both a denser and more highly stained roll of negatives. The difference is what I estimate to be approximately 20 %....for both stain and density. Perhaps as was stated by someone else the film is made at the same plant using Bergger's specification. The paper backing is the same, the film base appears the same, spools and paper tape the same. Anythoughts? -- LF website http://members.bellatlantic.net/~gblank For best results expand this window at least 6" at 1152 x 768 resolution |
