Have any of you knowledgeable photographers used efke KB 25 and/or

Rollei Pan 25?

 

I have just received 5 rolls of each film from B&H and was looking to obtain any

information I could about the difference between the two and also any tips on

Development for best results.

 

I'll tell you what chemicals I have maybe I should use something els.

D-76 developer

T-max developer

kodak stop

rapid fixer (concentrate)

Hypo wash- I read that it cleans well and leaves no spots,

and also read that i don't need it.

 

 

Thank you all very much in advance for any help.

Dave Mac.

I have some experience with Efke 25.

 

I'd recommend an acutance developer and care to control contrast. D76 1+3 would be where I would start with what you have as this will control highlights better than TMAX which gives an upswept curve.

 

Keep agitation to a minimum, say, once every two mins and experiment from there. Shoot a rolls under averagely contrast conditions and cut a third off and develop than, then adjust times for the second and by the time the roll is done you will have an idea of what this combop delivers.

 

I found speed in 1:100 rodinal to be about 16-25 depending on lighting. I suspect you will get about the same with D76, perhaps more easily making the 25 mark.

You'll find a starting point for D76 here...

I've never used hypo wash, but you'll need some wetting agent for the final rinse. Only use three drops or so per film.

I should have mentione4d that another reason for dilute developer is to prevent dev times being too short and improve bite/acutance on this very fine grained film. It develops contrast very quickly, so be gentle.

 

FWIW I have found Delta 100 to offer greater resolution and finer grain, but at the expense of a more modern look. All depends on what you like and to my eye it looks very nice, only it is painfully slow for anything hand held.

You don't need hypo clear. It shortens washing times to get the fixer out, but since wash times on film are already short, it's not that much of a hassle to skip. On the other hand, it doesn't hurt and can sometimes help washing dyes in the film out.

Thank you all. What a huge help you've

been.

Im going for it this week- end and will

post my results if they are any good.

 

Thanx again
