I'm working with a photographer and we would like to know the advantages of having a sd card. This comes up because when he's shooting he would like to save the data and gray card info when he changes storage cards. So far the info is lost everytime he takes out a card and puts in a new one. Would an sd card be able to store this info?

What is a SD card and what is it used for?

I believe they were designed as a version of a MultiMedia card that has a lock on the side of them to make them read only. They are about the size of a postage stamp and half the thickness of a CF card. I would guess 4 SD cards are the size of 1 CF Type I card. Almost every PDA on the market uses MMC or SD card slots.

The SD card is a memory card for storing the (image) files, but the white balance is not stored on a memory card, neither SD or Compact Flash (CF). There are other flash card formats too, different ins size, capacity and speed.
As SD card allows protecting data, it's called "Secure Digitial Card". (Copyright issues)
The 1D models have the possibility to store the whole configuration on a card. In this case you must store / load the configuration by menu.
This gives you the possibility to have several configurations (one per card) that you can easily change the whole setup.
Is great to transfer the configuration from one camera to another too.
Check the manual for details.
I don't understand why the camera is losing the information when replacing the memory card.

Very happy with his 1DII

Why does he need to keep the gray card data on the card? Unless you are going back and forth between several cards, then it makes more sense.

By grey card info do you mean custom white balance?
SD is just another format like CF and functions identically except it has faster write times (in a MkII). Since the MkII has two card slots, you can store the setup data on a single SD card and leave it in the camera, and use multiple CF cards for photo taking (or vice versa). Just make sure you switch the MkII off before you swap cards, otherwise the camera will automatically switch to the other card slot and start writing photos there instead. Also, the SD card has a write protect switch which can be enabled.

is that in the manual and have you experienced this? This sounds terrific. I was looking for a way to cut the time to switch and this seems like a cool way to do it. Does it switch automatically when one is full? Or just when it's pulled without powering down, as you say.
Thanks for your time and research.

I can confirm this behaviour - If you remove the active card and there is another in place the camera will switch to it. Dunno if this is in the man but it works.

You know...I don't use the camera. He says the information gets erased when he removes his memory cards. I'm guessing he's losing his RGB settings and such. Are you saying there is a way to keep this info even when he removes his data cards. I'll check the manual.
Thanks.
Thanks.

There really aren't any settings you could lose by just removing a CF or SD card, unless perhaps the backup battery is dead which would be obvious, or if he's clearing the camera's settings inadvertently.

You are correct, and the original poster said:
... he would like to save the data and gray card info when he changes storage cards...
I shoot a gray card each time the light changes. And each time, I "submit" that image to the custome WB process to "tag" all succeeding images with that information. Sometimes, when I'm doing this as I move from venue to venue (like shooting a wedding), I'll go back into the same room and rather than shoot another gray card, I can just scroll back to the one I shot previously in that room. Those images from the gray card are on the storage card. If it gets full and I swap it out, I can kiss those gray card images goodbye for setting custom white balance in the camera (unless I want to swap the cards back in). I think he'd like to be able to have a second card in the camera to dedicate to his gray card images so it's always there to "inhale" an image into the custome WB process. The SD card slot is ideal for this. I believe he can also keep many sets of custom settings on that card.
I hope this clarify's why he's interested in the SD slot.
Now watch, he's going to come in here and say I missed it too

Custom white balance was my guess too. Hopefully we'll find out exactly what he kept losing.
