how to develop for my enlarger

<p>Hello all<br>

I have changed the enlarging head of my meopta opemus,from standard white bulb and diffuser glass,to meorhcom (colour).The colour head is placed over the orignial condensers.Now I dont know how to develop films, so for contrast index 07 or 05 because I have both diffused and condensers in the same enlager.seams anny of the dunco enlargers have the same kind of light head<br>

thank</p>

 

<p>I moved from a condenser head enlarger to a diffuser head (Meopta Magnifax 4a with Meograde head) and I increased my dev times by around 15 percent.</p>

<p>As Chris suggested, adding a little development time for your negatives usually works well for dichroic or variable contrast heads with diffuse light sources. Very few enlargers described as "condenser" heads are true condenser types - most use some form of diffusion, either an opal lamp or sheet of diffusion material in the light path. I've used the same development techniques for most of my negatives and they've printed pretty much the same on the condenser head with diffuser as on the dichro head.</p>

<p>Thank you</p>

<p>yep, condenser heads always give you a bit more contrast. I've found that most of my negs print at grade 2.5-3 on the LPL7700 diffusion enlarger and print at grade 2 on the ilford condenser enlarger.</p>

<p>If you listen to Ansel Adams he standardised on grade 2, so you should aim to develop based on that with the equipment you work on.</p>
