Number of photos on an 8gb CF card?

[Idnas71]

I'm sorry... this has got to have been addressed before, but I can't find it.

I'm going to be traveling through South America for almost 4 weeks coming up in November. I want to take advantage of the good rebates at SanDisk and get enough memory for the trip.

If a person decides to shoot in RAW *and* JPEG combined, how many photos from a 10 megapixel 40D would fit on one of these 8gb Extreme III CF cards? Not that I intend to use that method the whole time, but maybe I will. I don't know.

Addendum: Another question... mostly curiosity. When you review your pics and decide to delete some, does one action delete both the RAW file and the JPEG file, if you choose to shoot in duplicate like that?

[GaryS]

I shoot RAW only on my 10mp XTI, and it produces files between 8 and 10 mb, so I get about 400 on my 4gb card. I would suspect that a jpg would add about 1-2mb per pic or so....

Do you have the 40D already? You could just try it out on a smaller card to see what you get...

[TheWengler]

The camera reviews on this site tell you approximate file sizes at the various quality settings. You should be able to figure it out from that.

[Idnas71]

Thanks, GaryS. No, I don't have the 40D yet... it's on the slow shipping truck... probably another week before I see it. I could certainly wait and test it for myself, as you suggested.

I'd say that you'd be better off in this instance with a lot more CF cards. I went for 6 weeks to the Baltics and took 1,500 photos - that's an average of about 40 photos a day and it's somewhere that I'd been many times before. I'd say you should be thinking in terms of 200 photos a day or 5,600 photos total. In RAW on a 40D this is 12.4mb/image or about 70GB. That's several 8GB cards or pray and hope it works and get a portable hard drive. Just don't use the hard drive above 10,000 feet.

[GaryS]

When on vacation, I tend to shoot about 400-500 images a week.

Just don't use the hard drive above 10,000 feet.My Epson P5000 (viewer with hard drive) worked fine hiking around Tibet...average height around 14,000 feet...:cool:

[Idnas71]

Thank you for the replies. I just bought three of the Sandisk Extreme III 8gb CF cards and will take advantage of the full $160 rebate. I figure with reviewing my photos in the evenings and ditching the bad ones (there are usually a bunch of those), that should be sufficient for me. Part of the trip is a cruise, and I imagine the days at sea will not provide much photo-taking opportunity. When we hit the Chilean fjords, though, I'm looking forward to some great on-ship scenery.

I'm not sure of the elevation at Machu Picchu... I know it's high, though. I'm not taking the laptop, just the camera stuff.

[David Metsky]

Machu Picchu is rougly 7800', lower then Cusco which is 11,000'. There was a problem with CF II hard drives where they would sometimes fail over 10,000'. Since at the time they were the biggest memory cards available it was a big deal. I don't know if the same holds for current drives used in compact storage devices (like iPod disks).

That will be a great visit - hope they do not close it soon due to damage caused by...too many tourists...

I'd be reluctant to storage 8GB worth of once in a lifetime photos on any portable media with no back up at all. Lose the camera on the plane on the way home and you lose the lot and the trip is not exactly like a day trip to Disneyland in terms of creature comforts.
At the very least get an adapter for an iPod and transfer the images onto one of them or a portable storage drive that will allow you to copy from the CF card directly. At least if the back up drive is in another bag the chances of losing everything are greatly diminished.

If you get desperate, shoot JPEG and just be careful of your exposures and white balance...ie chimp a lot. :D

CF cards are small. He can put 'em in a zip-lock bag (to keep them all together) in a zippered pocket on his person. Kinda hard to lose them that way. I have more confidence in flash memory than hard drives with moving parts...although I personally take a laptop and external drive to backup anyway, and keep the external drive on me instead.

Just to clarify... the he is a she. :eek:

idnas = Sandi backwards.

Thanks, all... and I'll be sure to keep my damage to a minimum at M.P. I'm really not a hooligan when I travel. And I don't litter. :)

Nice. So are you jailbait (17) as well? ;) :D

[Idnas71]

Nah... more like mid-life crisis waiting to happen.

[cdifoto]

Oh so you're my age then. :D


So, come here often? What's a lady like you doing in a place like this?

[TheWengler]

Very subtle. :p

[cdifoto]

Very subtle. :p
Hey, I don't beat around the bush; I play in it. :D

[Idnas71]

What's a lady like you doing in a place like this?

Well, I'm really just a she, not a lady, per say. ;)

I'm here to annoy all the people who know what they're doing with silly questions like these. Mostly I just hang back and read, try to soak up some photog. how-to's and why-for's. Enjoy the photo galleries, too.

[Visual Reality]

Best deal would be to take the laptop, but leave it where you're staying. If there is internet access you can:

a. Set up a remote connection with your home computer
b. Log in from abroad and upload/download files

At the end of each day, set it and let her rip overnight...beam your photos out of there to a place where they will be safe. That way no matter what happens...even if you lose all of your gear...your pictures are home waiting for you :)

*Fast internet connection required. Above represents ideal scenario and may not be possible at all locations on Earth due to technical limitations such as file size, internet availability and time constraints.

[Idnas71]

Hmmm.... not sure I want to lug the laptop along, but it's not out of the question. It *is* my home computer, by the way. I've only got the one.

[Rhys]

Personally, I'd just get more CF cards. Either that or buy a portable hard drive solution and pray that nothing happens to it.

I was going to say with 83 posts you're not hanging back as much as you claim till I noticed you got there in 3 1/2 years:)

Personally I'd go for retaining originals on CF and keeping a copy on some form of portable disk. Oh and they'd never leave my person during the trip (short of not showering with a hard disk, I'd draw the line at that).

CDI I just love the way blokes manage to treat females over the internet the same way they treat males. :D

And yeah I know you were kidding.

[cdifoto]

And yeah I know you were kidding.
I was? :confused: ;) :D

[Joe Fisher]

I shoot in RAW only, I have several 8G Sandisk Extreme IV cards.
I get about 600 images or so per card.
My advice is if you plan to shoot RAW + JPEG, get a bunch of cards!
