  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

OLPFS NIGHT TEST

Elsie N said:
But does any of that matter if each shot was the same? My understanding was he changed OLPFs, changed the OLPF setting in the menu, then shot the same exact shot again with the new OLPF using the same settings.

This seems to verify that exchanging the OLPFs is a pretty easy thing.

Unless you are in a dusty environment or pressed for time.
 
It appears that you shot the LL shots when the stop light was green and the STH shots when the light was red. Was this not the case?

Dust and time issues are real concerns. It's not really practical to spend that much time and try to find a dust free environment on a non-hobbiest professional set. You might be able to pull off a switch at lunch, if you're lucky, but I would rather just have lunch. If you want both OLPFs then you should rent two cameras, or else pick one. Rare is the situation where switching would actually make sense. My typical sets run at about $1750 per shooting hour, all told, and many out there run at far higher rates than that. Renting a Dragon here costs $850 - plus there is the stress factor and the real chance you will get dust in there. If you rent two then you can switch instantly, and even have two lenses pre-readied. People should be smart about this.

Yes, I was standing near an intersection in the freezing cold. Wasn't paying attention. I will post another wide shot test in which I think the traffic light conditions are the same.
 
If you look at both files, set the llo olpf to 3200k and 0 tint. Now push both to 3200ISO and you will notice the difference and why the llo olpf got it's name. There's just more detailed info in the low end. The skin-tone/highlight olpf looks mushy and lacking detail in the low end. Not much info to save. Viewing both in Redlogfilm is illuminating as well.

To be perfectly honest, after shooting with both, I like the color of the llo olpf. Call me crazy.

Well said, Robert. I've got both OLPF's and have many times needed the LLO, but because of time and environmental constraints don't make the switch. It's really a shame this is the solution to get noise-free, high ISO, lowlight capability out of our Epics.
 
It's not the stoplights. That looks like the sensor calibration isn't actually changing.

If you look at the street lamps they go from yellow to greenish yellow. The stop lights wouldn't change the color of the street lamps.

Changing the OLPFs was very easy and I would feel comfortable doing it during a shoot, but definately away from the set. It was a quick switch, just get everything ready beforehand.. I would even feel comfortable doing the switch, blinded in an old Film changing bag if it's a particularly dusty environment. The rubbery OLPF housing acts like a spring pushing it out a little after you unscrew it. You just need to pay attention to the super tiny and stubby screws.. (you lose one and it won't sit flat) If you got big meaty fingers, forget it... The little wrench provided needs to be triple the length, and I almost wish it was straight instead of L shaped, because it's cumbersome to screw back on. But, it was probably made like that so that it can fit inside the OLPF box and be used as a backup. I would suggest using a proper wrench, which I ended up doing. And I also wish Red just gave you an extra set of screws with each OLPF purchase.

Is it just me, or is the left side of your frame have a pinkish tint to it on your STOLPF? I turned the tint down to 0 and ISO up to 3200 and got a weird sort of pink band on the left. Screengrab to follow..
 
See attached images... When you cycle through them, the left 1/3 of the image seems to have a pinkish tone...
