h? many photos can i capture with 6Mp,7.2Mp cameras with 1 GB memory approximately?

Answer 1

I have an example for 5 MP cameras. You can look this over and do the math for your cameras, since they are different.

You also must understand that this information is based on using the highest resolution, largest image a 5 MP camera can produce. If you use smaller sizes, the storage capacity increases immensely.

Put the card in your camera and see how many frames it says you can still hold on the card. That's the only really accurate way. Well, even that is an approximation, because the camera does not know how large your next picture will be. It's like your car predicting how many miles of fuel you have remaining in the tank when it doesn't know if you are about to smash the gas pedal to the floor. For instance, if you take a picture with a lot of more-or-less uniform sky in it, the memory used for a full 5 MP picture will be considerably lower than a 5 MP picture with huge amounts of detail.

If you are thinking of buying a 1 GB card and don't have one to check by putting in your camera, look in your owner's manual.

If you lost your manual, you can do some estimates and some calculations. A 5-to-6 MP camera will make files about 3-3.5 MB in size for an "average" full size, maximum resolution picture. Sometimes more and sometimes less. The theoretical MAXIMUM would be 5 MB, right?

One billion divided by 5 million = 200 pictures.

If the file size if more like 3.5 MP, though:

One billion divided by 3.5 million = 285 pictures.

Do the math to draw your own conclusions about lesser file sizes.

If you shoot a mid-size photo with "normal" resolution, you might even be able to get about a thousand on the card. Check your manual for details.

Answer 2

several hundred because i have a 1GB card and i can hold several hundred pictures on my camera.... i haven't had it maxed out yet
