Memory Card I have my setting on Raw. But it only holds a few pitures. The memory Card is a 1GB. Which setting should i use to get more pictures. Or do i need to get more GB's?

RAW format uses enormous file sizes. Smaller memory sticks will be used up with just one single picture when using the RAW format. You're confirmed this when you said it only happens when you use RAW format. You need to use a larger memory stick, if you want to use the RAW format.

That depends on your image size and image quality settings. A 14megapixel picture will take more space than a 3mp picture and thus you'll get less of them to fit. There's a chart in the "Number of Snapshots/Movie Recording Time/Voice Recording Time" section of the manual (page 136 in my copy) that gives an estimate of how many pictures at each setting combination that will fit in internal memory and on a 1GB memory card. A 4GB card will hold about four times as many as a 1GB card.

Bear in mind that these numbers are estimates. The actual size a picture file also depends on the subject. A picture of a finely detailed scene will take more space than a picture of a blank wall, for example.

The problem is that the camera can take pictures faster than it can write them to memory. It buffers a few in a high-speed memory location, but once that memory is filled, it has to be emptied to your memory card.

Your options are:
Use a smaller image size. Most cameras support small, medium, and large formats. Typically something like 2 Mpix, 5 Mpix, and 10 Mpixel images. Smaller images take less time to write to the memory card. If you are shooting in RAW format, this makes the problem even worse. If you don't know what RAW format is, you probably aren't using it.

Depending on the camera, it might support a higher speed than the memory card. SD is slower than SDHC, which is slower than SDXC. Check your manual and see what the maximum speed your camera can support and ensure your card is at least that fast. (IF the card is faster than the camera's ability to write, that doesn't improve things more than having a card as fast as the camera).

Be careful with your shots. There is probably an icon or counter that shows how many pictures left until if stops taking pictures. If something good is coming up, hold of on taking any pictures.

Buy a camera with either a bigger buffer or a higher speed interface to the memory card. I know, this one is a drag. My first DSLR could take only 9 pictures, then same problem.

try to reformat the internal memory and the memory card. press the menu button, select set-up menu, scroll down to format. Make sure to transfer first all your pictures to your computer before formatting the internal memory of the camera and your memory card. Try to update also the firmware of your camera. You can go to this website ( www.kodak.com/go/downloads) to download the latest version of your firmware.

maximum memory supported  for polaroid a300 is only 1GB.

Samsung only guarantees that a 1GB external memory card will work. If you look at the user manual on page 77. I just used a 1GB memory card instead and it worked fine.
I am not saying that no memory cards greater than 1GB will work, but if it doesn't work or stops working then it is because the software for the phone is not set up to handle it. I had the same issue and had to switch to a 1GB card.

You did not mention the make or model of the camera. Your symptoms seem to indicate you are using internal memory rather than the card. Card typically hold from 200-2,000 high quality photos (depending on the size of the card and the camera).

Another possibility is that you have a high end camera and are shooting in the RAW format. RAW is only for the more experienced users who post process their work. If this is the case switch to JPG.

Note reducing the picture size only makes the pictures lower quality and is only useful if you only post them on the web.

you need to adjust down the resolution you are shooting in. Fine JPG vs RAW makes a big difference on how much memory goes into each image. RAW will mean more data in each image, but fewer images will fit.

If youre using exposure bracketing, especially when raw+jpeg is used, this is saving out massive amounts of data to the memory card. Have you tried using a faster (80x) memory card and/or just using raw alone? You can always make the jpeg at the computer later.

Change file format from raw to JPG. It saves small jpg for preview when using raw format.
