gurney_tim Posted July 1, 2006 Share Posted July 1, 2006 I have posted a few threads on this topic when my EI for FP4+ was at 200 Iquestioned "everything". It was the battery in the lightmeter (pentax spot) thatwas the culprit...... Anyway these are the results I have now finalised. The zone 1 density is a bithigh on N+1 and N+2 (diff enlarger) but guess this is one of the issues tocompromise in order to reach a density of +/- 1.30 in the VII, VII and VI as youcontract the scale. The results were obtained using a 150mm xenar with copal 0; exposure that is midrange and F16. The lighting was mounting board with diffused daylight EV reading16 openned 5 stops for the Stouffer 21 step 5x4 negative. Developpement in HC-110 dilution H (1:63) at 20 deg celcius, dip&dunk agitationconstant for the 1st 30 seconds then every 30 seconds (1 lift to the right, twovertical up and downs, 1 lift to the left and 1 up and down = about 10 seconds).Fixing is with ilford rapid fixer. The dev times and EI: N-2 = EI80, 5'00"N-1 = EI80, 5'40"N = EI100, 7'30"N+1 = EI100, 9'15"N+2 = EI125, 12'30" The is on the attached file. Oh yes! the negatives enable easy exposure for printing that I do on a Devere504 ilford 500 equiped with RH design analayser 500 (great time killer and papersaver...... The negatives are packed with details that I can burn/dodge asrequired to get the "image I saw on that ground glass and imagined in my mind" Hope the above will help some of you even if personnal findings are necessarythey may provide a starting point. Any comments would be welcomed as I know that the ladder is a long one to getthe perfect print... Tim Link to comment Share on other sites More sharing options...
john_shriver Posted July 1, 2006 Share Posted July 1, 2006 I presume all those densities have had film base + fog removed? On T-MAX 100 in 35mm, I'm getting 0.20 just for film base + fog. (Although it is rather expired.) Link to comment Share on other sites More sharing options...
gurney_tim Posted July 1, 2006 Author Share Posted July 1, 2006 Yes they are indeed. Link to comment Share on other sites More sharing options...
james_noel1 Posted July 2, 2006 Share Posted July 2, 2006 ENjoy it whileyo can. I suspect when you have the shutter cleaned and adjusted your EI will be lower. In other words, I believe your shutter speeds are slow. This is no problem so long as they are consistent. Link to comment Share on other sites More sharing options...
