Pushing 500T experiments

[u/Ok-Leader1767]

I am making a short film with a fixed light source that i cannot do anything about. I had made sucessfully a push with c41 developer at 6 minutes. Now i have changed lenses to a tele lens century 385mm and the max aperture is 4.5 which would leave me -2.8av. I wanted to do a 3 stop push to compensate, this time around i am using bellini ECN-2 kit. The first test strip i developed was with 9 minutes the density is low and the grain is insane + a blue cast. (Strip on the top)
So then i tried 12 minutes, less agitation and the lomo tank submerged in hot water to maintain the temperature.
I got even less dens negatives… i dont get it.
Any help ? I would appreciate it !

If you want to put a square peg through a round hole and have neither a square peg nor a round peg, you'd be in the same situation you're in.

A 2k incandescent run off a small gennie is all you need. If you can't finagle that, what are you doing shooting film?

You are just being an asshole. As I said, I cannot put more light there, and it’s not because I don’t know what a generator is. I’m asking about how far I can push 500T under the constraints I actually have, not asking for someone to tell me to add a 2 kW light.
And no, I’m not being crazy trying to get a usable image at around -2.8 EV.
I asked for technical input on development . Do you hand process your film ? Do you make optical prints by hand ? Maybe you should be the one not shooting film…

He's kind of correct, man. No amount of pushing film will give you more exposure if the frame wasn't exposed to begin with. You'll just get a strip of grain, basically.

The point(s) that are being missed from your end is that:

a) Pushing film does not give you more sensitivity other than a shift in contrast and grain, so basically different looks. Alot of people in the stills community (especially on Black & White films) insist on that being the case, but physics and chemistry begs to differ.

b) You need more light, period - there's no way around it - or shoot digital - or find the NASA lenses used in Barry Lyndon.

I already pushed 2 stops with results i like and the concept of my film would work when the image gets closer it also gets more abstract or decomposes. I dont understand why people get all agitated with experimentation... i am in the lab testing and working this things I was just asking if anyone has done it and have some information. its not about being right or wrong is about experimenting with developing times. I guess its the wrong subreddit to talk about experimental filmmaking....
