Size the recorded image file

Neither. The camera is taking pictures at 5 megapixels resolution. The file size of the image is only loosely related to the resolution. You'll note that your pictures are all different sizes. The size is dependent on the content of the picture. If you take a picture of a blank wall or a plain blue sky, the file size will be smaller than the file size of a picture of a cluttered scene, because it takes more bytes to record detail.

If you look at your pictures in your image viewer, you'll see that the pictures are all the same dimension (width and height), regardless of the file size.

Image size: Press the FUNC/SET button. Use cursor-up/down to select the current image size at the lower-left corner. Use cursor-right/left to select the desired size and press FUNC/SET.

File size (compression): Same as above, except choose the item just above the image size.

Full instructions are in the "Changing the Recording Pixels/Compression (Still images)" section of the manual (page 57 in my copy). If you need a manual, you can download one from the manufacturer's web site at

Hi john_lewis3,
Use UDF option when creating an image over 2GB!
I hope this helps!

Hi,
The image size determines the size of the image file that is recorded when you take an image. The larger the image size, the more detail will be reproduced when the image is printed on large format paper. The smaller the image size, the more images can be recorded. To change the Image Size in the Camera, press and select the MENU-->Image Size-->Desired Size [(640×480)VGA or (2592×1944)5M] The quality of the VGA Image is very less when compared to the 14M.
Good Luck

In general, the file size of captured image depends on which image size and quality you have selected. Since the image size may vary depending on scenes and subjects, these are approximate values only.
