Related Questions and Answers

Q: 1. In what light can I use it? Reflector? Could you advise me?

A: These gels are small sheets, slightly smaller than a sheet of office paper. They are not intended for large and powerful lights, which require a roll of gel rather than a sheet. These are best used on lights with a suitably small lens/aperture, such as a small LED panel or a fresnel like the Arri 650 or lower. If you are using hot lights, keep them a few inches away or the heat will melt them. They are fantastic for coloring smaller LED lights.

Q: 2. IF I JUST DO PHOTOSHOP WITH 50 MEGABYTE RAW FILES, WILL THE 24 INCH I MAC WITH 16 MB OF RAW BE ADEQUATE?

A: This would be dependent on many factors such as what will be done to the RAW 50 Megabyte files. How many will be edited at a time? The Apple Mac Studio with M1 Max (Early 2022) might be better suited for this task.

Q: 3. Can I increase the Hard Drive capacity on this imac?

Q: 4. 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: 5. On Apple.com, it mentions that the new iMAC is configurable with Ethernet. But doesn't say how or what adapter would be needed? So how do you connect to Ethernet?

A: As of the writing of this post, built in ethernet is not yet configurable on our site, and would require a USB-C ethernet adapter to receive network over ethernet.

Q: 6. Can this filter be used on a regular speedlight or is it only for strobes?

A: Sure! These high-quality acetate sheets can easily be cut down to fit any size required. You can simply rubberband a piece around the head of your speedlight or cut it for use inside a fitted plastic diffuser. Easy-peasy!

Q: 8. 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: 9. 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.
