Checking the Gate

[Florian Stadler]

Having dust on the sensor can go unnoticed pretty easily when shooting close to wide open. I would recommend tilting up to the sky when shooting outdoors and stopping down to a 22 or setting up a brightly lit white card when shooting indoors and stopping down as far as you can. Check on a large monitor for sensor dust.

What are people using to clean the sensor? Is Red recommending anything in particular?

Is this a pretty good solution?

What other procedures are people developing for checking the gate after a shot is circled as far as insuring everything is recorded properly and "in the can"?

Can we still use canned air?

[Graeme Nattress]

I'd avoid canned air. Canned air can have lubricants or propellants fly out, along with the air, and land on the OLPF, which will make it hard to clean. I'd personally recommend using a powerful hand blower instead. That's what I use on my DSLRs.

Thanks Graeme! Still have one of those in my kit -

My personal recommendation in order of what to do (stopping at
any of the steps if all is good and checking with a sensor scope or looking a flat field stopped down):
1. use a blower to clear all loose dust from the olpf and lens port walls etc..
2. if there's still dust remaining, use a sensor brush
3. wipe down port but not olpf to clear any loose dust on the port walls, etc.
4. use a blower again if there still some lose dust on the olpf.
5. use a sensor swab w/ fluid like photosol.
6. use a blower if necessary.

Thanks Deanan! I've always just used a sensor brush and blower on my DSLRs and have had very good results with that.

Sounds like a solid strategy.

Thanks Deanan

Deanan,
Some dumbass client of ours put his finger on the sensor and left a nasty mark on it. Which of the photosol product do you recommend as they have many types on their website:

OMFG! We have a major ID10T on set. :angry03:

Just regular Eclipse is good. I'd skip the the sensor brush step as you
don't want to get the grease back onto your brush.
