Be on time and be reliable. Bring the clothes, make-up, accessories, etc., that you promised to bring. Make sure your hair, nails, skin are in faultless condition.

Do not demand money (e.g. for your time, for signing a model release or for posing in a particular style) when you arrive for the shoot, if prints for time was agreed and everything was discussed beforehand.

If you are doing nude shots, wear loose underwear and no bra for at least two hours before the shoot. Underwear leaves ugly pressure marks on your skin that can take forever to disappear.

If you absolutely must make telephone calls, do it immediately when you arrive on location and keep it brief. Then turn off your mobile phone until after the shoot.

Do not cancel without sufficient notice and for no good reason. The photographer has already spent time and money preparing the shoot.
