Photo transfer from SD Card to computer

christine antaya , Jul 05, 2010; 03:29 p.m.

Please help?

< p>I have a Canon 7D, new.

I was using a Canon 10D.

When I take photos with the 7d and copy them from the SD Card to the computer, they copy as very large JPEG fi les. Some are as large at 10M. These files are too large to transfer via email, as well as too large to st ore.
What can I do to fix this? Fix the photos that are now loaded onto my computer, as well as fix this from hap pening in the future?
Ive tried various search engines in an attempt to figure this out , but to no avail.
Any a nd all advice is welcome.
Thank you in advance,

First of all it sounds like a review of the User's Manual that came with the 7D is in order.
You could change the "quality" setting, but that would only defeat the purpose of having the 7D.
Is it a "post processing" issue if you are shooting in RAW. Not knowing what software you are using, my only other suggestion would be to maybe "resize" in Microsoft Office Picture Manager if your computer is using Windows and has this program.

I am certain some other's will chime in here too!

Sorry I'm really not much help, but you probably need to provide some more information. i.e, Computer Operating System, Photo software, shooting mode, etc., etc.

Your new camera creates larger files because it is collecting more data in the first place. If you want to be able to e-mail those files for casual viewing, you probably not only want to compress them more, but likely also want to down-sample them to a lower resolution suitable for on-screen viewing. I'm guessing you don't usually want to e-mail someone a files that's thousand of pixels wide, right? Depends on why you're sending it to them, of course.

As for storing the files: honestly, if you can afford a 7D, you can afford a couple of $75 external disk drives with hundreds of gigabytes each of storage (always make two backups of your files).

Just remember: if you tell your camera to produce lower-resolution, smaller files, that's a one-way street. If you find that you want to make a large, high-quality print, you can never get that data back again. Consider shooting and storing RAW or large JPGs, and then just making smaller versions of the files for when you want to pass a particular one around.

Your 10D was a 6MP camera. The 7D has 18MP. So, yeah, the image files are much larger. The main reason we pay the big bucks for a 18MP CMOS is to print huge pictures. I made many 12x18 and 24x36 prints from my 7D and the detail and smoothness is stunning.

Like others have said, shoot full rez (18MP) and store the master image files on an external hard drive (1TB hard drives are dirt cheap at Costco, NewEgg, etc.). Sooner or later you'll want a big print. Use your master file to resize for web/email and "save as" under a new name to preserve the master intact. If you have a lot of images to resize you can use the batch processing features in common apps like DPP and PS. I've resized and exported hundreds of images with a few clicks in Aperture. I'm sure LR has similar abilities.

If you have PS you can record an action that will resize for you automatically, as well as a lot of other stuff. I have two one for making the standard size for display on my web site and one for creating the thumbs. When you run it from Automate, Batch it automatically does an entire directory. So, just make a directory for each shoot. If the last ting you do when recording the action is to close the image it will work for any number of images, as there's never more than one open at a time.

I just ordered a 1 tbyte external HD from Bestbuy for $75 including shipping, internal HD without the case and power supplies are usually $10-15 cheaper. I think that works out to 6 to 8 cents a gig. With storage so cheap theres no reason for you not to save full res files. External are much slower but very portable and can be used on a number of computers and left powered down when not in use. It difficult to damage file on a HD that's powered down.

Download Picasa. It's free, and for what you are apparently doing--it will do a very good job.
Aside from the simple and effective editing tools, it has an E-mail button. Highlight the picture,
click E-Mail, and address your default E-mail. You're done!

While we're on the subject of back-ups and seeing whereas storage is so damn cheap and computer manufactures generally don't provide you with OS disk to repair or re-install OS and most problem with crashes happen to the windows directory, I'd suggest that you make a back-up of your entire HD on external. Then you you have a failure, even a complete HD crash. You simply boot-up machine with emergency disk, restore to the day it left the factory, then drag and drop your entire HD.

If you have Windows 7 you can tell it to continue copying files after error (like file in use). On my laptop I have Windows 7 on my desktop I'm still using XP Pro. So there were a few files in config folder and a few in a another folder, (old age creeping in don't remember the folder name, but it was another minor folder with 8-10 files in it) that I had to copy over file by file. It only took a few minutes. Then from run any program run regedit and export your registry to back-up HD. You'll now should be able to completely rebuild you HD very quickly.

Shooting RAW and manipulating your images in post process is the best way to take advantage of your 7D's features. Download a free trial of Adobe Lightroom and give it a go. Your images will likely look so much better than the jpgs you're shooting now, since conditions change, and if you forget to adjust your camera from cloudy to sunny, your image will suffer.

Tigerdirect.com was selling 2 TB internal hard drives for something insane like $40 this weekend. That will hold a lot of images. You can get a casing for $25 or so to make it into an external drive...the only disadvantage of these over typical external drives is that these also require a power cord to be used. IMHO, a fair trade considering the storage space to dollar ratio. You can always get a portable external drive to take with you if you need a drive when you travel.

Christine - you have spent the money to get a high resolution camera. I would suggest you continue to shoot using the full 18 MP and just re-size for email etc...

By the way you camera uses CF cards (not SD) and the old cards from the 10D will fill very quickly. On the 7D you need at least 4GB cards and 8 is better. You should also be aware that you need to pay for the fatsre cards if you wish to take advantage of the cameras 8 frames per second.
