A Question that I hope is not too daft concerning the Storage Capacity on a 256 mb Compact Flash Card. I had found that using the Jpeg Format at Max Resolution...2592x1944, I tend to be able to get approx: 100 Images to the Card. If now, I start to use the RAW Format, how many Images would My 256 Card be capable of holding? Cheers...HC.

was wondering that myself :/

silly, your questions aren't daft!!! well, i use a compact flash card. For JPEG format at max resolution, my cam can hold 108 images on a 256 mb cf card. so ours sound close to the same. if i change to raw, i only get 11 images. terrible isn't it! However, when i use my 1 gig card, if i use JPEG at max resolution my cam can hold 449 images. if i switch to raw format on the 1 gig, my cam can only hold 49 images. Not sure if this helps....i'm the one who's daft tonight! LOL! Good luck!

Do You know Cynlee....in the Thousands of Words that have passed between Us...this is the first time We have discussed...Photography ....sigh...click click...fi fi.

That is just the answer I am looking for Sheila....You are a Gem!

me? a gem??? what kind???? can i be an emerald please? i want to go to Oz and see the Wizard, please!!!! I need a complete overhaul!!!! :)

now Brian I know we've discussed photography...lol :] & Sheila!! 11 you say? oh my... how big are the files? right now one photo .jpg is averaging 1.05MB... so one .raw would be like 10MB? o.O!

well, i guess one file would be 24 mg. cindy. now i forgot, our cam also creates a JPEG anytime you use RAW or TIFF. so if your cam doesn't create a JPEG along with the RAW, you might get an extra image. nuts isn't it!!!! :)

oh vay, told you i wasn't a pro looks at cam like a cheap date

you're nuts, cindy!!! LOL!!! :) i ain't no pro either!!! at least YOU shoot in the RAW!!!!!! :)

Now that's something I'd like to see! ;oP Tedz, most cameras tell you how many images they have left before the card is full. Erase you compact flash card completely and then set you camera to it's RAW mode. That should tell you how many you can fit. --kort

Good question. Do you still have your camera's manual/instructions? Perhaps it has a chart of these specs.

....also....I think I know this much...you will get a signifiganct less number of RAW images recorded on any memory media(except something called anti-media) than jpg files...but You prob. already realize this. -Peace/Jeff :-)

Thats the trade off...as well of other things Teds...my RAWs tend to be anywhere between 6Mb to 10MB...depends on how much scene info was shot at the time...as others have mentioned, just shoot a card full of Raws and see. Nice to see you have noticed that RAW has more to other than jpgs in an earlier thread.

I shoot with a 1GB compact flash. In the best quality, largest size jpeg I get about 250 images. With Raw I get about 135. This will of course vary by camera make, as not all camera's use the same level of compression on their jpegs. And of course sensor size matters, (it always come down to size matters doesn't it)

On my Oly C5050 I get 34 RAW images on a 256 MB card. With my JPEG setting on high, I get 71. Just turn on your cam and see what it says! ;oP

Hmmm, that was for my xD card. When I switch it over to the CF, I get 33 RAW and 69 HQ JPEGs. I wonder why there is a diff...both are empty and are 256MB... <:^/

interesting to hear all the differences!! Jimbo, there's a HUGE difference between the size of your RAWs and mine!!! Randy, Kort...you guys are getting a lot more RAW images than i am. what's up with that??? it comes down to size??? LOL...

Size doesn't matter, it's the smile it puts on your face that counts ;-) (",)

I would think that it would be something like 40 Raw images depending on whether it saves a jpeg with the raw (most likely)or just raw alone.

On the 10D I can get 35-40 raw images on a 256MB card.
The 10D is 6.3MP and the files are between 5-7MB

That's sounds about right Simon..... according to the D70 manual..... raw files average about 5mb depending on the scene shot. Average about 44 raw images on a 256 card.

I have only got one 256 card and dont use it very often as it is the slowest card I have, so it is the last choice. The 10D has a very slightly larger resolution than the D70, so I guess that may make the slight difference. I almost always get between 38 and 40 images, as I shoot mainly landscapes, the compo and colour range is similar in many situations. Also (and I am not sure is this applies to RAW) ISO value has an effect on file size, the higher ISO the less images/larger file size, that is the case with Jpeg.

Tedz, I got scared when I first read the header "compact flash", I thought we were about to start a discussion about midget perverts in raincoats. Whew, glad I was wrong! My Olympus uses "Smart Media Cards", and doesn't have "raw" image capabilities, however it does shoot hi res tiff, and they use up about the same space as raw 8-12 meg, so the numbers being thrown around seem to be right. I don't have any 256 cards but I have several 128's and the numbers seem to average out to what everybody is getting.

Bloody hell, Jack, you HAVE to lower the tone with smut, don't you?!? FWIW, My Fuji is also too old to have RAW mode, but an uncompressed TIFF takes 12mb too. (",)

IMO speaking about uncompressed TIFF file size in comparison to RAW will confuse the issue as an uncompressed TIFF is far larger in file size than the RAW equivalent. A 6MP RAW image is approximate 5-7MB when this is processed to TIFF or even Photoshop PSD etc it will be approximately 18MB for 8 bit and 36MB for 16bit

See? See what happens when I try to get involved in anything technical?!? I'm wrong. FFS...... ;-) he he he (",)

My cam is capable of recording in TIFF...but not RAW. I am not jealous though. What's RAW? It is not a standard file format...it is specialized and used by the advanced post work people for fine tuning(i've heard that many actuall like jpgs)...All this sounds cool...I know this much. I think I remember reading that RAW is the way to go if you are going to print something, but maybe I am incorrect. RAW is big in file size, but so is TIFF (but I assume not as big as RAW), and w/RAW You can adjust the white balance and other stuff after the fact w/significantly less banding and other digital defects like is common w/jpg after the fact postwork(in case you didn't get it right when you shot the photo). I don't know why this is the case...maybe because RAW if cool. Also I heard RAW is less noisy...esp. at higher speeds. Also I have heard that post work is almost always necessary with RAW images since the camera's processor doesn't help with this kind of thing as it does w/jpgs and TIFF. I know very little about RAW...only what I've read about it in bits and pieces. I think the name RAW sounds pretty cool. -Peace :-)
