Following on from another thread where the Mod says it may not be appropriate to comment on the mistakes people make, I believe that fair warning should be given to any person who thinks that because they have a camera and their friends say they take good photos, this does not mean you have what it takes to be a "Photographer"
Many like me, here, have years and years of experience and yet are now finding that people want "cheap", so, ask Fred he has a camera, why pay the pro £1000 when Fred will do it for £200, why well this is why.
When I shoot weddings, rarely as I hate them.......
1. Two cameras minimum, BOTH with DUAL card slots
2. Spare batteries and charger
3. TOP quality best on the market cards formatted in camera before the shoot, FOUR per camera so that you can change them after each venue, so as to not put all your eggs in one basket
4. Laptop, to backup the card after shooting
5. Video camera, NO extra charge, you can sell it later to them, but at least IF the stills fail you have something else to offer FREE
6. Separate camera mounted pointing at the couple from a different angle, triggered by the main camera. BACKUP.
7. TWO flashguns with Stofens for indoors, Stofens are NOT for outdoor use so 2 Lumiquests for outdoors
8. INSURANCE, INSURANCE, INSURANCE. PUBLIC LIABILITY AND INDEMNITY.
9. Know year gear inside out and upside down.
Feel free to add to the list, most like me don't think what is needed it comes naturally so I will have missed things off.
