    Hi,

    Hope someone can offer me advice.

    I have a ballet school booked and as well as the usaul school photos in there uniform they are looking for the whole school to be in there ballet gear.

    As there all white dresses dont really want to use high key backgrounds and I was thinking of using some coloured gels (blue and red). Never used them before.

    Any adivice on background (i assume 18% grey), lightiing set up, etc. Have 2 months to prepare and get ready and get in a bit of practice.

    Thanks

    The darker the background, the more saturated the colour.
    Try lighting a white, a grey and a dark brown or black background with a gelled light. If you do, you will understand how to choose the appropriate background.

    Lighting a white background with coloured gels will give you a tint whereas darker background will give very saturated and strong colours.

    As above.

    it's worth pointing out though that although saturated colours can only be obtained with dark backgrounds, overexposing the background can produce pastel colours if required.

    Also, you'll find when you experiment that you need very even lighting on the background

    The more light you put on the backdrop, the more that will be reflected, thus increasing the risk of colour contamination on the subject.

    How you light the backdrop depends on how you want it to look.
    If you want a strong spot of colour, then use a harsh light, either bare bulb or silver reflector on the head.

    If you want weaker less saturated colour and more even, then place gels on the front of a softbox or on the baffle inside a softbox.

    You may find that ambient light and / or spill from the main & fill lights will dilute the colour down

    High temperature gels are the safest to use and probably the only option if photographing in schools or other premises.

    A better option may be choosing a pastel coloured background and lighting it normally.

    Hi,

    thanks. V useful.

    This is the sort of effect I am looking for, but with more of an infinity curve.

    I also have plently of time with the school, and big area to set up in.


    Thanks

    Try here for a suitable backdrop.

    I would err towards a coloured backdrop rather than using gels to get that type of effect.

    The Sapporo backdrop looks quite good.

    A nice hand painted background with pillars or sweeping staircase may be worth the investment if you think it might tempt the parents into buying larger images - sod the credit crunch Smile

    Thanks again,

    Not really keen on the painted backdrops, I think they look a bit tacky.

    Any suggestions on setting up the ligths to get that gradient effect?
