No. You need:
A colour enlarger (obviously!)
A drum or slot processor (such as Nova). You can use trays, but it means
fumbling in the dark for three process steps and is a bit smelly. I used
to use a drum but got fed up with washing it between prints. A Nova is a
lot more convenient, especially if you're doing a lot of printing.
Temperature control is not too critical provided you know what the
temperature actually is. Nominal process temp is 24 deg C (= about 76 deg
F I think - someone will no doubt confirm!) so you can do it at room
temperature. Before I got the Nova I used to heat my darkroom to 24 deg C
and wear light clothing ;-) Temperatures from 22 to 30 deg C are fine.
There are three (plus a wash) steps to the process:
At 24 deg C, there is a 3 minute development, followed by a 30 sec wash in
clean water.
Then comes a 3 minute bleach, folowed by a 3 minute fix. If using trays or
a Nova, you can turn the lights on once the print has been in the bleach
for 30 secs or so. Finish off with a wash as usual. It's possible (though
I've not tried it myself) to use oridanry b/w dev and fix. It's possible
to get some contrast controil by changing the dev characteristics. You
must however use the Ilforchrome bleach. AFAIK no-one's been able to
produce an alternative formula.
The processing's easy, getting the colour balance correct is not so easy.
If you're printing from Kodachrome, it's a lot easier. Modern films like
Velvia can cause some problems with colour balance and contrast.
But - when you get it right, the results are wonderful!
Have fun :-)
