paper developer: high diluted versus low

And some people think cellphones are a suitable replacement for dedicated cameras...

Wow

Just bought a 2nd edition for 12.95 UK Pounds

Last time I checked about a year ago they were 150 to 200 UK Pounds

I read a Library copy and have wanted one for my own ever since

Thanks for the tip off

They are, if the dedicated camera is a disposable...

The again, aren't cell phones disposable?

Hi,

if i for example use a 1+9 paper developer, develop a print and do the same for a 1+4. (kentmere vc select, 90 seconds at 20 degr celc.)

I notice that the 1+4 has more deep blacks than the 1+9.
Has anyone got the same results?
extending the time of the 1+9 to for example 6 minutes will result in the highlights start to develop off white.

Until last week i always used the 1+9, but now i start to question myself if the 1+4 for give me a improved quality image.

What you experience is typical. As you continue to dilute some developers the the print tone will change to "warmer", which will reduce D-Max; the developer will lose capacity after fewer prints; more time is needed to reach full development, or more exposure to deepen shadows.

One night I kept diluting a developer further to see what extreme I could find and the result was a very red/brown print with low contrast/shadow density. It was fully developed.

What we saw was that the white highlights were getting off white after 10 minutes (in dark area developed). Just like leaving on your safelight for an hour with a print in the developer.

But I have to wait for the book now...
