Analog film photography and cameras

get a yellow corrective. Filter quality is everything though!, a cheap one will do fuck all, some yellows are more yellows than others, if you get my drift.

also in dev, try slowing it down, instead of 1:25, slip to 1:50, or even 1:100. with some dev's that helps gain a bit of contrast, others it does the opposite, so do some research on what you use.
Temp too, yeah you can dev faster / slower at higher /lower temps, but they affect contrast/ grain and all sorts too. 20c is just a safe bet, not always the best!
Stand development I've found works quite well. I stand dev'd my last roll from a 50s uncoated 69 folder and it made a noticeable difference over the normal agitate agenda. But you've got to be pretty confident, as it can go tits up pretty easy!

filters might help. and low iso film. and a little bit of sunshine.
generally, it's love it or leave it piece of glass. hope you'll love it.
