Walked the yacht last weekend. It's big enough, 7' shiny and tinted ceilings, 3 decks, top is open.

Looks like the ceremony will be on deck 2 with B&G against a clear glass nook between two spiral staircases over the stern.

Took a few test shots shooting wide, but in looking at this album I found under "show your stuff" forum here by Nicholaus Haskins (boat looks pretty similar) I really like his tighter shooting style.

So; I'm thinking of favoring my 85 f1.8 on my crop body for natural light shots, with probably a 10-22 + flash on the other.

I've never shot a Yacht before. It screams for wide and ultra-wide but the tighter shots of a slight tele (85mm) look great.

Opinions? Advice?

Well, this question is one that I have a hard time answering because you are the only person who can truly answer this one. Why is that you ask? Because you know what kind of gear you have, you know what style of shooting you do, and you are the one who will have to haul the gear around all night. What do you typically shoot with at a wedding, not all your gear that you shoot with, but what is your work horse lens? For me I can shoot an entire wedding with my 5D and a 24-70 2.8 lens. When I was shooting Nikon, I could shoot with just my D200 and a 17-55 2.8 lens. Although, for me personally, I think I could also shoot this job your talking about with the two lenses you suggested but I'd have to do it with two bodies. I hate changing lenses and would rather keep two cameras on me. So, by suggesting to us that you'd probably use the 10-55 and a 85mm, then I believe you've already answered your own question.
I'm sorry if I came across as snotty, I just woke up. I'm sure if I responded to this email in a couple hours I'd do so with more tact but the under lying message would be the same. So grab your two lenses, have some confidence in yourself, and go shoot this job.
Hope this was somewhat helpful. Good luck.

Thanks Ron, lol. Caffeen.

My workhorse is the 24-105 f4 IS + flash, I have 2 30Ds. If I had a 17-55 IS that would be it.

I carry 2 bodies so the 2nd can have a nice prime (usually 35L) for the artistic break from the solid photos the 24-105 spits out.

I'm asking because flash looks difficult - low shiny ceilings, ultra cramped space. Even at noon, light was dim with an empty deck, so f4 ISO 1600 may not cut it.

Then seeing Nicholaus' gallery, I just thought I'd make a call for the voice of experience.

Hey Vyger,
I debated on shooting wide as well. The B&G covered the mirrors, and brass poles with lacy fabric, just to cut down on glare and reflection.

Thats probably the number 1 thing I could recommend from shooting on a yacht. I decided to shoot tight with no flash..as the ceremony was in the afternoon. Visit my site for more photos from this wedding...."Ken and Sandy"

Good luck bro.
