Using colored gels on studio backdrop

Hi Neil and to all others .
On your discussion of coloured gels on back drop can u confirm to me that using gels on cotton grey back drop is not as rich as solid wall back drop ?
Im still experimenting with this and it seems hit and miss.
I had set up a grey back drop in my bedroom for testing and it had taken me a while to get a rich orange back drop from the gelled flash i was using..
In the end my thought process was in a mess , from having the strobe further away from the backdrop , closing down the zoom head on the flash and then rewiden the flash head .
Also changing my white balance for a warmer richer tone.
Generaly what would your thought process be for setting your full cto for such affect or any other cto for such a nice coloured back drop. .?
I would invite all others for there kind input

    Stephen ... the lack of saturation might be due to the close proximity of your main light. 
    Try taking a test shot with just the light on your backdrop, 
    and then compare it to when you have your main light also switched on.

    Do u know what u may be right to the fact my bedroom is so small compared to a studio , so that main light may be diluting the gelled flash.
    Ive managed to hire a local hall for £30 for sif hour amd its massive , But i tinker in my bedroom with such small room.
    Thank u . I will let u know the results

    The flash that has the gel on it can dilute the color if it is a higher power setting also. You may need to double up gels or use a heavier cut or back off the power.
  • In addition to what MikeZ said, you can also use ND gels.  I have ND gels ranging from 1 to 4 stops that I often use in conjunction with colored gels.  This allows me to go much lower than the 1/128 minimum power setting when in manual on a 600EX-RT.
  • Hi mike z. And rs.
    Many thanks for your input. Sorry for delay getting back work is heavy at the moment.
    Can i ask also when shooting with the gel on. What is your white balance , Because when u think about it , the gel is kind of acting like an ambiant then mixed with white flash , I did experiment and found it better on cloudy , giving the more orange look , .
    Thanks

    Your WB is set to whatever your main light is ... and since you're shooting in RAW, you have flexibility.

    There are three types of gels I use:  First are ND (which doesn't affect WB at all; just allows for lowering flash output).  Second is color-correcting.  These allow to you have your flash match existing ambient lights (e.g. tungsten).  I will usually use existing WB presets at that point, or sometimes will dial in a Kelvin setting.  Third is creative where I don't concern myself with WB at all.  Reason is, I want the extra warm, or extra cool or whatever colors.
  • Thank u both for the above. , Im pepping for a shoot , and i want to use this method Neil had done with the full cts gel on the back drop .
