agfa apx 25 black white

i've shot a fair amount of Efke 25 and 50 and it looks great developed in D-76. it is pretty

contrasty tho cause it's orthopan film, so expect more contrast that usual on a sunny day.

it's also great for shooting on overcast days. normally, you'd get flat images when it's

overcast but since efke is more sensitive to blue light... and clouds trap more blue light in

the sky, so you won't have to worry about pushing or overexposing your film to recover

any density.

 

when i was developing my own film last summer and would print it, i would put the

contrast on the enlarger around 2 1/4. when i started having the lab do my film, contrast

was around 3 - this includes ilford pan f+. when i print efke 25 or 50, i have to put the

contrast down to 1 1/2 or 1 to get a print that doesn't look extreme. so in my opinion,

expect more contrast as compared to pan f+, which is still a great film.

@mark: There are NO rumours that APX25 is coming back. There are just some people who spread their phantasies over the net, and therefore this topic comes up from time to time.

 

@john-paul: There is absolutely no connection between the terms "Orthopan" and "high contrast". If your Efkes came out too contrasty, you simply developed them too long. BTW, the Efkes have a very straight curve, so they profit from a compensating developer.

 

After the demise of APX25, several distributers claimed to have a substitute; mainly Efke/Adox25 and Rolleipan 25. Both films are very different from the APX, and they only have the "25ASA" in common with the Agfa film.

The Fotokemika website (manufacturers of Efke films/papers) lists both the 25 & 50 speed films as "orthopanchromatic".

 

Nevertheless, here's a group for Efke 25 shooters:

 

Efke25 Drive

 

I use it, and find it looks best in Rodinal, and printed on the Fotokemika Varycon fiber papers.

 

JMO YMMV

APX 25 is gone and will not be coming back and that's just the facts. I have also shot Efke/Adox 25 and Rolleipan 25. These films are none like APX 25. They are ok films to me. I have shot them both and like the look of them in HC-110. I rather shoot Iflord Pan F. But that's just me:-D any way.<div>00Jjjn-34689684.jpg.cb7cfe09ee20b302bca608cb7dd6a0f8.jpg</div>

i see plenty has happened since i last posted. altho the issue was addressed, i never said

efke was ortho film. i said it was orthopan film, as in orthopanchromatic, altho some

people say that orthopan is just another way of describing panchromatic film. efke's

website, as well as fotoimpex, does describe the efke 25 & 50 as orthopanchromatic and

the efke 100 and 400 as panchromatic.

 

there is also a difference between ortho film and ortho lith film. very often i see the two

terms thrown around as if they are the same. i recently shot a roll of rolei ortho 25 and

was given a choice of high contrast development or more continuous tone. i chose

continuous tone (HC 110 was used) and the guy at the lab told me that developing it high

contrast would render images with just black and whites. i think he may have been

thinking of what ortho lith film does.

 

about the way i develop my film, it certainly seems like the lab is able to develop it to a

lower contrast index as compared to when i'd do it in a small tank... maybe i was agitating

too much. i tend to use D-76 which isn't exactly a low contrast developer. the negs i've

gotten from efke in D-76 have always been pretty even, altho i'm not opposed to having a

little extra punch in certain shots.
