Here´s a quick extract of the product page taken from www.adox.de:Quote:
Mirko, can you comment on the advantages of the Silvermax developer over other developers?
ADOX SILVERMAX Developer
SILVERMAX developer has ben especially formulated for the SILVERMAX 21 film.
It is activating the silent reserve sleeping in each SILVERMAX 21 film by expanding the photographic capabilities of the film.
The DMAX is reduced and the curve extended. Thus SILVERMAX developer yields in combination with SILVERMAX 21 film a total of up to 14 zones in the negative.
Ready to go Kit for 6 films including ADOFIX and ADOFLO*
50 ml to mix 1,5 Liters of developer and to process up to 6 rolls of film*
250 ml to mix 7,5 Liters of developer and to process up to 30 rolls of film*
(*In a Jobo tank filled with 250 ml of developer per film)
Dilution: 1+29 (10 ml plus 290 ml of water to mix 300 ml)
Developing time for SILVERMAX 21 film:
11 Minutes at 20°C
(Agitate the first half minute continuosly and then tilt every 30 seconds once)
I have underlined the important line. The developer is specially formulated to modify the characteristic curve of the film in a way that you have a normal grade in the midtones but extended coverage in the ends. You could theoretically take another developer and start adding or taking out chemicals and run test rows to optimize this developer as well. In the end (depending on the type of developer) you might end up with similar results.
If you just change the dilution/developing time you will not get to this extend of curve modification.
However: Any deveoper will develop Silvermax to greyscales and a latidute which is at least comparable to other high quality B&W films.
When we introduced Silvermax some people stated that "etxra silver" was just a marketing gag as it would be useless. In some way they were right. If you do not use a specially formulated developer you "give away" most of the advantage in negative/positive work.
(If you reverse-develop the film however you benefit from the extra DMAX).
I hope this makes sense to everyone.
Thank you, Mirko. I'll order the developer as well.
> Silvermax is Scala 200, which is based on APX 100
That may be misleading. Silvermax is made using the scala recipes, but its is not Scala from 2005 or earlier. It is fresh material.
I value the forthrightness of Mirko an Adox, all details on all product of Adox are available, nothing is hidden. And I value of course their initiative to enrich the market with own products.
