The LEE Filters 3x3" #11 Yellow Green Polyester Filteris a basic contrast filter, primarily for use with black and white film, that moderately darkens blue and red tones, lightens green tones, and helps to subtly increase overall contrast. It also helps to better simulate a natural tonal response when working with panchromatic film under tungsten lighting conditions. There is an approximate 2.5x filter factor with this filter, requiring an increase of 1.3 stops for normal exposure.

This 3 x 3" / 76.2 x 76.2mm filter is manufactured from high-quality polyester materials, is durable and easy to clean, and can be cut-to-size or mounted within filter frames for use.

Q: 1. Will this Pouch also store the Foundation Kit?

A: I have not tried to put my foundation kit in this holder. I don't think it would work if you have the 100mm system with a polarizer ring and 9 filters.

Q: 2. Are the filters separated by something, or will they scratch against each other when taking a filter out or putting it back into the pouch?

A: They are separated by a soft piece of cloth, but there is a small gap at the bottom where they might. From my experience, carrying four filters as well as the mounting devices, there hasnt been any scratching.

Q: 3. Is this fireproof?

A: No, the LEE Filters Quick Location Pack - 24 Sheets (10 x 12") listed above are not fireproof. According to LEE Filters, they state that their standard gels are "heat resistant" to 180° degrees Centigrade (356° Fahrenheit). The filters should be used at a slight distance from halogen, tungsten, and some high-intensity LED lamps, but may eventually melt and will require occasional replacement.

Q: 7. would this work on aputure 120d ii? would it melt away or will stay fine

A: These gels can be used on an Aputure C120D II. While LED lights produce much less height, it is always a good idea to attach the gels with a bit of air space between them and the light.

Q: 8. Can i use this in front of broncolor siros lights with broncolor's reflector in front? If yes, then how can i attach it?

Q: 9. So I recently purchased these gels to cut out and use with the filter tray on the Aputure barndoors. Upon turning my 300d mkii up to 100%, it burned right through the center. Should I just be clipping these onto this light? Or are there other filter alternatives that can go in those trays?

A: It would be best to clip the gels to the barndoor leaves in order to allow for more air space.

Q: 10. Will the Big Stopper fit with the metal case?
