Is this the 'darkest/deep blue' version they have? Last blue gel I got (Lee 201 and 202) was far too 'white' for what i'm looking for. I want a deep blue
Asked by: Cameron
CTB is a correction gel it is not meant for adding color. If you want a rich blue color Primary Blue would be a good option.

Will this melt if I put it next to my speed ring on an Arri 1k open face?
Asked by: Kevin B.
These gels are heat resistant but will eventually fade and distort. I've only seen them melt when in direct contact (or very near proximity) with a halogen lamp. I think you'll be ok for awhile if the gel is on the outside of a lensed speed ring. Maybe check for sure with Rosco or Lee.

These can taped and wrapped to any configuration. I've even cut them to make filters for my PAR lights

Asked by: Kevin B.
It depends on how close to the light you have it. These gels are pretty durable and withstand quite a bit of heat but can melt if left near the heat source to long. I don't use your type of lights but I have taped these directly to the front of my dynalite strobes with nothing in between. They get pretty hot and the gels stand up to it perfectly fine as long as you don't just leave them sit there with the lights on for long periods. I usually adjust my lighting then put the gel on and shoot so the gel isn't on for too long. If you use a holder and put a little space between the light and the gel this should definitely work but if you are taping it directly to the light like I do then keep an eye on them because they can melt if left too long with the lights on.
