Default mathematics

Hello,

Say I have the following 12x Lexar compact flash cards:
256mb
256mb
256mb
512mb
128mb
16mb

All amounts are MegaBytes (MB) I just didn't cap the mb.
That is a total of 1,424mb of space for images/videos/files/whatever.

Could someone tell me how many basic, good, great, RAW photos that would hold taken from a coolpix 5700?

1424/ (divided by) 2.5MB (as in if all images were 2.5MB) that would be 569 photos for all the cards.

I couldn't find the size chart for the 5700 so I didn't know what is what.

Please advise.

thanks so much.

When I take pictures in RAW mode they usually range in size from 7MB to 8MB.

What about for these,
basic:
good or whatever is equal to this:
great (probably RAW which would be 178 photos @ 8MB):
fine:

and whatever other shot modes there are.

thanks.

Do realize that these numbers are estimates for any jpg picture. Some pictures compress better than others, for example blue sky compresses really well. Very cloudy skys don't.

I don't believe the CP5700 compresses its RAW files (but I could be wrong.) If it doesn't, then I thought the size of a RAW file would be almost exactly the same every time. But if it is compressed, then the same logic applies.

good points. So I guess I can't really use math to my advantage in the case to figure out how many images I can fit on 1424MB. I'll just say a lot!

Put a 256Mb card in the camera and set it for raw. Look at the indicator that tells how many shots you have left and divide that into the 256. Better yet look at a raw file on your computer and see how big it is. Divide that into each card separately and discard any fraction remainder.

I have no idea why Phil is getting variation in his raw files. They are normally a fixed size like TIFFs. 7-8 is relatively inefficient. The Minolta A1 for example gives 5Mp raw files in a 5Mp camera, which is about as efficient as you can get. Older models in the series took 9.5Mb raw files which is about as bad as it gets. Even so, they were always the exact same size.

You can just glance at a folder full of your JPGs at best quality JPG and make a rough mental estimate of the average size. They donít usually vary wildly until you get down to higher compressions and I donít recommend you use those. Your mental estimate will usually be better than the cameraís for JPGs in my experience.

well you could shoot in RAW all the time and just empty the card often.......(is it worth the extra time converting a such on the PC?)
