Photo Forum / General Photo Topics / General Topics / January 2008Question about memory card capacity.
Approximately how many pictures can you store on a 2gb memory card at the highest quality when using a 7megapixel camera. I looked in the manual that I downloaded but couldn't find the answer to this question.

See link: http://www.clarkvision.com/imagedetail/compact_flash_card_speed/index.html It is a good idea to either put in a new card, or download your pics, when you've got your card about 80% - 90% full.

It's a better idea to do so more frequently, if you value your images. Many don't realize there is a MTBF factor in every CF card.

If you read the article, you would note that the tests were not inclusive of all cards, nor of all systems. Mr. Clark noted in particular that he had not thoroughly tested cameras that use more than one subdirectory, and he suspects that such cameras would be less prone to the varying transfer speed. However, my heads up was posted simply to advise photographers that, if they intend to store large numbers of files on a single card, they might want to be vigilant for an increase in camera sluggishness. And, if ssuch an effect becomes noticeable, it is easily remedied.

I don't pay much attention to memory card as hard drive (which I agree 100%), so I don't think it will make much or any difference base on few simple things. - First, Memory Card is Memory *not* disc to have fragment issue like hard drive, also memory card is usually too small comparing to hard drive to make a big issue - Second, the writing speed of camera is too slow comparing to the top speed of Memory Card to notice the difference (even if it does happen). And many people format the memory card quite often (I do because it's lot faster than deleting hundreds or sometime over thousand photos). > <snip> >> > But, keep in mind that, as you near the card's capacity, the transfer [quoted text clipped - 28 lines] > And many people format the memory card quite often (I do because it's lot > faster than deleting hundreds or sometime over thousand photos). Did you take the time to read the article? You should, it's really quite interesting. You might be surprised how much the speed can decrease when some cards are nearly full. However, if you haven't noticed a slowdown, then you don't have a problem, right? But, some people might actually notice the problem, and they might be interested in what is going on, and what to do about it. A "heads up" is just that, a red flag which you can choose to act on or ignore. I can tell you that it might be a good idea not to walk under a ladder with a painter working up top. You can choose to go around, or you can choose to push your luck and zip in behind it. The result? Who knows? But, I for one like to be forewarned. Good Luck, Dudley > Approximately how many pictures can you store on a 2gb memory card at > the highest quality when using a 7megapixel camera.

If they are jpeg images, they will be compressed - so the compression factor is relevant. If compression is about 10 to one then about 1000. If you're doing raw then again, it depens on whether your raw files are being compressed - raw files uncompressed will be probably be larger than 21mb. There should be a chart somewhere in your owners manual - it may or may not mention a 2gb card, but you can easily scale up from what is there. > Approximately how many pictures can you store on a 2gb memory card at the > highest quality when using a 7megapixel camera. I looked in the manual that I > downloaded but couldn't find the answer to this question. My camera has 7.1 mp, and at the highest quality JPEG, gets 312 pix on a 1 GB card. I presume, therefore, that a 2 GB card would hold about 624 pix. When you turn on my camera Canon SD 800, the screen shows in the lower right corner, how many pix are left on the card.

Its 573 images. As some of us have mentioned that the number of image is depending on your setting, and not all images will have the exact same size so you may have +/- 1-3% depending on the size of memory card.

Its 573 images. I doubt it's that precise - the amount an image can be compressed at a certain quality setting will depend on its content. > In article <Xns9A32DA29A97B4jockstrapprotectthen@194.117.143.38>, Jock > Strap [quoted text clipped - 10 lines] > I doubt it's that precise - the amount an image can be compressed at a > certain quality setting will depend on its content. The manual did say that this value was only an approximation and that the number may vary depending on conditions and recording medium. > Approximately how many pictures can you store on a 2gb memory card at the > highest quality when using a 7megapixel camera. I looked in the manual that I > downloaded but couldn't find the answer to this question. In general it depends on your setting Highest vs Lowest RAW vs JPG or RAW + JPG etc.. - And your camera should display the number of images base on your setting. It may not be 100% correct but pretty close - Or you just check the average size of several images (the size will vary depending on color) then do a simple math and you should get the answer. |
