RAW vs sRAW

Shooting a wedding this weekend. What do people recommend? I am assuming sRAW is of lower IQ than normal RAW?

Would be handy to be able to use sRAW to get more pics on the CF, but don't want to sacrifice IQ..

Thanks guys

I'd shoot Raw.
Buy more CF cards…

I guess it depends on how you define image quality. Obviously, you're operating at reduced resolution. For a wedding, I don't think this is particularly advisable. On a 5DMII, even sRaw is pretty good resolution, but if this is a client your shooting for (as opposed to a wedding you were invited to where you're just planning on taking some pictures), don't leave such things to chance. I've only shot a couple of weddings as favors for a family member and close friend, but I'd say shoot full size raw, and double the amount of CF cards you think you'll need. The last one I did was a very small wedding, and I believe I brought 2x16GB and 4x8GB cards with me, along with my laptop to upload the photos between the ceremony and the reception (that was more about having a backup than running out of space). You can buy 16GB cards on New Egg or Amazon for almost nothing these days, so go crazy.

The more images that you cram onto a CF card the more you risk loosing in the event of a card failure.

I'd probably rather to have 4 x 4Gb rather than 1 x 16Gb as if I lost a card I'd lose only a portion of the images.

Furthermore, I'd shoot the bridal preparations on one card, the pre-ceremony on another, the ceremony on a third - well you get the idea.

If shooting a wedding sRAW is not an option.

Shoot full RAW, it has more flexibility for recovery. sRaw is half baked already.
