With the wedding market literally flooded with so called "wedding photographers" I have seen so many disappointed couples whose photographer hasn't lived up to their expectations and had their day ruined by receiving poor quality images or has simply taken the couples money and not turned up on the day! I had exactly that scenario and stepped in to rescue their day with half an hour's notice!
Not everyone who owns a camera is always a photographer, especially a wedding photographer. It's OK having the equipment but knowing to use it is a different matter and crucially can ruin your day.
Photography is all about light and how to use it to good effect, especially artificial light (flash) and knowing how and when to use it. A flashgun can make or break an image, too much and it will be over exposed, too little and it will under exposed. Get it right and you have the perfect shot. Photographers who use professional software can usually rescue an over or under exposed image - but not always! The detail has to be there in the first place.
Anyone can point a camera and press the button but not everyone can get the composition right and that includes posing your subject and getting the light right.
More and more wedding venues are asking to see a photographer's insurance certificate and without one, are not allowed to photograph there - imagine a couples day ruined because of a simple thing like insurance. The photographer wouldn't have a leg to stand on and could be sued and no insurance means they won't have the means to compensate the couple.
So please, when booking your photographer, always ask if they're insured and if in doubt, ask to see proof. It's also a good idea to take out wedding insurance for that reason alone and for peace of mind. I'm covered by Public Liabilty and Professional Indemnity Insurance and any second photographer I use will either have their own or will be covered under mine.
A professional photographer would've spent a lot of time and money on training, professional camera equipment, marketing and advertising etc., and they will have insurance.
The saying goes (and this relates equally to wedding photography) "If it sounds too good to be true, then it probably is." A decent professional wedding photographer will set you back at least £1,000.00 for a full day with images on a USB, album packages will cost more and the average cost of wedding photography in 2017 was £1,480.00.
