Definitely check pics as you go...and have extra cards. Have a great trip.

I am having trouble with pictures from a 16 GB AGFA SDHC Card purchased in Ireland...I can see the pictures as they were shot but it's like a filter appears in front of the photos (almost like a double exposure)...I am on a Mac and tried opening pictures in Image Capture, Preview, Photoshop and Picasa...the result is the same. I looked up recovery software but don't know if it's worth it. The pictures are not vital but I would like to save the pictures if possible. Attached is a screen capture of 3 images where the color/filter can be seen. Any advice would be appreciated.

I don't know how you created this screen capture, but I think you'll get better suggestions if you post the original photo file. Be sure to store original when you post the image.

As stated above, I have the same issue with my CF card. I get the same type of picture destruction. Now I said I was going to try a few things to find the cause.
I viewed the pictures in preview mode on the camera, and the pictures were just fine. (RAW)
I put the CF card into the computer, and opened up the pictures in Photoshop Bridge. Of about 20 pictures, 3 were no good, with streaks across at least 50 %.
I then opened the viewer (preview mode on a Mac) and looked at the pictures, all were OK.
I opened ON1 software, and the pictures were just fine.
I then put in another CF card, took 20 pictures, and had zero defects.

This would lead me to believe there is an issue between Canon's software and Photoshop, but not with other programs. That does not leave out the card being an issue either, but I will have to shoot several hundred pictures on my new card to see if the problem repeats.

Again, zero defects with the SD cards.

Here is an image...it seems that the preview is all right so I am going to try on a pc and there are a couple of programs that were suggested to me which I will try...

That's exactly what I get Tony, a totally wiped out picture. Only happens on my one CF card, and only with Photoshop. I do not have an issue with the second, new CF card. They are both SanDisk, one is several years old, the other is brand new. I wonder if there is a technical difference between the two cards that is causing Photoshop to corrupt a few files. Quite the mystery. As stated above, I tried three other picture viewing methods, and they were fine. So the good news seems to be that if you have a file like the above, try opening it up with a different program. Maybe even resave it.

Thanks...so far every program I have opened the pictures in (not just some of them) have some kind of distortion on part or all of the image...luckily I didn't have a lot on the disk and if I lose the images it's not the end of the world.

You should be able to extract the preview image from the file. it looks the raw data is corrupted unfortunately. For screen use the preview is probably good enough for web / screen use. Unfortunately it will be too low resolution for printing.

I wouldn't be keen on reusing that particular card, you might mail it in to the manufacturer and probably they will send you a replacement for good will.

Looks like a bad memory cards. Buy a new card from a reputable source.

Those are corrupted files... but the question is "why are they corrupted?"

If you've been removing the memory card from the camera, using a separate card reader for downloads... try instead attaching the camera to the computer with a USB cable and downloading via that.

If you have been connecting the camera via a USB cable... try instead removing the card from the camera and downloading via a separate card reader.

If your camera has WiFi connectivity and can do so, try transferring an image via that, instead of a wired connection.

NOTE: However you do the "download", ALWAYS "copy" images to your computer... don't "move" them."Copying" leaves the originals on the card until you can confirm that the files were safely and securely copied over to the computer. Once that's done and you are certain all the files you want to keep are safe, you can simply format the card in camera to "mark" what's on it to be overwritten.

Doing the above might help you determine if it's a connectivity issue or an incompatibility between a card and a particular card reader.. or if it truly seems to be the card itself at fault.

I agree with other suggestions, you also should be certain that your computer's software is up to date.... especially if this is a newer camera and you see similar problems with other memory cards.

But if it's a single memory card doing that... others are okay and don't show the same problem... it's most likely a bad memory card. A "low level format" might fix it (mapping any bad sectors on the card so they won't be used). Your camera might be able to do this. If not, do it in computer, then do a quick format in camera afterward. NOTE: a low level format WILL ERASE EVERYTHING from the card. (A quick format doesn't erase, merely marks as okay to overwrite... So long as the card hasn't been used for new images, often old images can be recovered after a quick, in-camera format.)

However, as affordable as quality SD memory cards are today, even if it seems to work there's little reason to do a low level format. You'll always be concerned the problem will crop up again!

As a side note, I haven't seen the Agfa name in a long time.... It appears to be primarily being used in Europe and the UK. Agfa used to be common in the U.S. too. They still sell film and a few other things here, but nowhere near the range of photography products and accessories we used to see offered.

I wouldn't be surprised if someone else makes those cards and the Agfa label is slapped on them. That's fairly common practice. Kodak, Duracell, Polaroid, Vivitar, Delkin and many others outsource many products and rebrand them. I forget which of the common brand names (maybe Polaroid), but some years ago I almost bought some CF memory cards that looked like a great deal. But when I researched them it turned out they were actually manufactured by Dane Electric and their card speed ratings were very misleading. They cited "read" speeds, not "write" speeds which were much slower and are far more important for camera performance... If I'd bought and used hem, they would have made my cameras sloth-like! Re-branders like the above, some of whom actually don't make anything themselves, also night change their sources frequently. So a product that's great today may not be the same in a year or two. For example, Vivitar at one time used serial number prefixes on their lenses (none of which they made themselves), that showed they were out-sourcing them from at least 17 different companies.

Some folks have suggested there are actually only a few companies and factories producing memory cards.... That most are re-branded for sale under the names we see in the stores. The question then is how tight quality control is applied. A well-known and respected manufacturer might demand and get the most carefully screened products to put their name on, in order to uphold their reputation. Other companies may be less discriminating.

I have no idea what Agfa is doing these days. They used to be a fairly well respected photographic company.

I have the same problem with one of my SanDisk compact flash cards. It started out to be one or two pictures in a few hundred, then more. Now it is about half the pictures. I reformatted in camera, to no avail. I have an SD card slot in the camera, which I use all the time and never had an issue. Now I have a new camera, a Canon 5DMK4, and the same problem with this same CF card. I just bought a new CF card, so I will try it today. My suspicion is that the card is bad. If the new CF card does the same thing, then SanDisk needs to explain the problem to me, explain why their cards are not working.

You probably already know this, but CF cards can go wrong if the pin holes get worn. A pin in the camera may get misdirected. Happened to me and now I’m very careful when I insert the card in the camera as well as the reader.

If all else fails, there are damaged card recovery companies out there. I happen to have literally broke a micro SD card into two pieces, it is at the recovery service now! Not as expensive as I had thought it might be.
