Thanks for all the comment guys lots to digest and think about!
To answer a few points/comments.
The bride is under no illusion that I have any experience shooting weddings. Ive told her straight that "I dont do people" many times.
In fact only a few months ago when I started pushing myself into street photography, we had a discussion about how I would hate to do a wedding. This was before she knew she was up the duff and her dream wedding was a long way off. She helped me out getting into the street stuff and knew how hard I found it at first.
Although Im sure there is an element there that she really wants me to do it, I know her well enough to know she wont be upset if I say no. However I also know that if I did do it, and it didint go as well as I hoped, she wouldnt bear a grudge, she just isnt like that. I believe in myself just enough to know I could get some good shots, my fear/doubts is something going wrong, or missing a cruicial moment due to lack of experience. Ive only ever been to three weddings, one of them was mine, so Im not really experinced in the whole "wedding process" as a guest, yet alone a photographer. I have howveer spent many, many hours viewing pictures on here and elsewhere of other weddings, so I have some idea of "the shots" that are expected.
The last wedding I attended was my brothers, in May. I wasnt asked nor expected to be a photographer, I was purely a guest and I took my Panny GF1 and 20mm lens just to get some snapshots. They had hired a photographer from my Sister in law's native Holland. She had a brand spanking new D800, mounted with a 24-70, and thats it.
I was highly concerned at the time, that there was no direction, even my wife said the same. Everyone was just milling about, and despite being in some glorious surroundings, there were no group photos taken, no set photos of the guests or of the parents/bride etc.. I actually took upon myself with my GF1 to get the shots I could see the official photographer just wasnt taking. If it wasnt for me, there would be no photo of the bride and groom with my 80 year old grandparents, or with both sets of parents, or of the other guests. The official photographer was just focused on the B&G soley.
My point being, I could see what was needed and did it.. However saying that, there was no pressure to expect me to do it, which could have made my head clearer.
My wife is going to be a bridesmaid, so Im not going to see/be with her anyway for the majority of the wedding, so In a way its actually a blessing to give me something to do rather than be billy no mates at the back. I dont really know her other friends that well, the ones I do know well are also bridesmaids.
I promised myself this year would be the year I pushed myself out of my comfort zone. I spent 6 months of 2011 stuck inside my house, unable to move after major surgery and it felt like such a waste.. As I mentioned, I started doing some street photography, something I really didnt feel comfortable doing, but the more I did it, the better it felt. I handled the one incident I had calmly and professionally.
I will need some extra gear, I dont have a flash gun, and I could really do with another body to mount a wider lens, as my 70-200 will be mounted to my D700. I cant afford to buy a body outright, so I will need some finacial input from the bride. She has already said she will pay, however how much I dont know yet... Around £300 I would guess at.
I have very kindly been offered by Yv a second shooter/dogsbody position at an upcoming wedding in September, I need to check my diary, and it is the other side of the country which isnt ideal, but the experience will certainly help.
I feel more confident having slept on it, and the thought of her paying for the tat I saw from the other wedding would make me sick to the stomach.
To sum up, I think Im going to go for it, I feel more like I want to now, I feel like it will push me forward, Ive been bumbling along for many years, just shooting for myself, never getting anything out of it other than a few stock sales and a "nice image" comment every now and then. It would be a huge boost to my confidence and lets be honest, my ego, to have my photos really admired and cherished by someone.
I havent got any proper photos of my wedding, just snapshots from guests, and it does bother me at times. It would have been nice to have some proper images to look back on in 30-40 years or whatever.
So, I'll talk to her tonight and see.. I noticed on Faceache someone sent her a link to the other photographer from the other wedding, so I need to make up my mind and get in there quick If I decide to do it to save her a lot of money and crappy photos.
