The Tiffen 6 x 6" 82C Light Balancing Filter helps to increase the color temperature by 400K in order to cool the image slightly in order to match the color quality of illumination. When using an 82C filter, you will be able to attain 3200K balance when the prevailing light source is 2800K. The cooling effect of this filter requires a 0.6-stop increase in exposure for normal results.

This filter is made using ColorCore technology, a process that involves laminating the filter substrate between 2 pieces of optical glass and grinding flat to a tolerance of 1/10,000th of an inch. It measures 6 x 6" / 152.4 x 152.4mm.

Q: 6. Hi there. Can I use my Flashpoint R2 pro 2.4 GHz Transmitter for Sony (XPro- S) with this Godox AD100 pro? Thank you

A: Yes this will work Godox makes Flashpoint.

Q: 7. What is the Guide Number for this flash? Or what is the f-stop at 10 feet at full power at ISO 100?

A: Unfortunately, there is no conversion to convert watt-seconds to guide numbers. A watt-second is a measurement of energy, measuring how much power (watts) is delivered in one second. A guide number is simply a tool to allow you to calculate the working exposure you may use from a flash with a set reflector degree/beam angle when the flash is on-axis with your subject. The issue is the guide number can vary widely from the same flash head if you use a different reflector size or if the flash has a zoom head. The exact same flash with a zoom head set to a telephoto zoom setting will have a much higher guide number than the exact same flash with the zoom head set to a wide angle setting. Hot shoe flashes have built-in reflectors and are designed to be used as-is (even though they can be modified). Studio strobes (such as the Interfit Badger Unleashed strobe head) are designed to be modified; they typically do not have built-in reflectors, and instead have a bare-bulb design. A reflector is not included with the purchase of the Interfit Badger Unleashed​ strobe head. The exposure measured at your 10-foot distance at ISO 100 would vary wildly depending if you used the light unmodified (in which case it would have a much wider 180-degree beam spread compared to a hot shoe flash), versus using a 7-inch reflector, versus using a magnum reflector, versus using a 22" beauty dish, versus using a softbox/umbrella, etc. As such, when comparing studio strobes, it is easier to compare the maximum power output from the unit with the output of other studio strobes rather than to give a guide number to calculate exposure which will vary depending on the modifier used on the strobe.

Q: 8. is the flash able to differentiate between a full frame lens and medium format (Fuji GFX) focal length when zooming?

A: According to Profoto, "there are no known issues with the auto zoom function on this flash".

Q: 9. Is the Sekonic LiteMaster Pro L-478D-U Light Meter compatible with Alien Bees lights?

A: The L-478DR-U has the built in PocketWizard transmitter which can be used with the PocketWizard FlexTT5 and AC9 to actually do power control of your Alien Bees. I do this. Works well. The L-478D has not radio transmitter so it is necessary to put it on Cordless mode and press to test button on your lights or trigger the lights using one of many light triggers on the market. This too works very well.

Q: 10. What could be the angle of coverage? I am trying to figure out if it would have enough spread with a 48" softbox to cover dancer group portraits (maybe 6 front row, 6 back row). Any suggestion appreciated.

A: You would get better spread using a umbrella than a softbox. Impact makes a good 60" for shooting groups https://bhpho.to/2PxLRtr.
