Scan disk banding.

Hi there. I have a question regarding some images that I have on some discs. There seem to be a multi-coloured banding on some part of the image, not all. As well, I can only see this once it has been imported into LR or PS and not on the camera.

Lets see what you're talking about

Have you looked at them on any device other than your computer and the camera? Try posting one here and maybe some hoggers can play around to see if they get the same banding.

It's most likely card failure, I see it occasionally. Try downloading the images direct to a file folder. Then download then again to a DIFFERENT file folder. Compare the images and see if the corrupted images are identical. If so the card is the problem. If not, a card reader or USB cable could be the problem.

As Capture48 said, it would be good to see the issue. However, it sounds like corruption in the file. The trick now is to determine if the corruption is actually in the file on the card, or is it getting corrupted as you copy from the card to your PC (which is usually the case). Read what MT Shooter has to say, also.

Use a little isopropyl alcohol on a Q-tip to clean the card's gold-coated contacts. A subtle fingerprint can act is a intermittent insulator during information transfer. If clean and still misbehaving, as Carter (MT Shooter) said, it is a damaged card.

This happened to me a couple of months ago. I noticed some banding on a few images from a trip to Arizona. I attributed it to dirty contacts, so I cleaned the contact points with isopropyl alcohol as has been suggested here. I used the card again for a hot balloon shoot a few days later. Result? Zilch, nothing, nada. No images were on the card. I threw away the card and bought some new ones. The cost of a few new cards is cheap compared to the loss of those images.

Dirty or damaged card. Try cleaning contacts, if still acting up, toss it in the trash! They can also get corrupted if you interrupt a read-write cycle such as not safely ejecting them (on a Mac especially).

As others have said, without you posting image(s), equipment being used (disks??...??), a shot in the dark-- I have experienced "banding" on SDHC lower-speed 32MB chips with Nikon D7200. (i.e: 45/MPS)- there's a difference in read/write speed capabilities- particularly when taking bursts, as camera tries to process through buffer- BUT - MY image problems ARE viewable (show) on on-camera DIJTT? (did I just take that) display.
I suggest you purchase newest/fastest (95MBPS minimum transfer rate, reputable-brand) media and see if you continue to get "weird results." And YES - "losing" those images sucks! Good luck. Hope you solve the problem.

Did you really mean 'scan' disk or are you speaking of the company product named 'San Disk'?

Get a new card. Shot the same scene with both, if that appears on both you have another problem. This can also happen during long exposures, light comes in through the eye piece. Solution, cover the eye piece during exposure.

This result would be IMMEDIATELY obvious, because the reference JPG that appears on the camera LCD is derived from the image saved to card. This is why it takes a few seconds for image to appear after the photo is taken: you are seeing the recorded image, not the captured image. No image displayed means no image recorded.I used the card again for a hot balloon shoot a few days later. Result? Zilch, nothing, nada. No images were on the card.

A few years back, that happened to me. I downloaded what I could and threw away the 3rd party SD card. That was my last 3rd party SD card, now it's Sandisk all the way!
BTW: I've never had that happen again

I had that problem several years ago. Traced it to a bad card.

So many people are so quick to just throw a card away. Most major brands have limited lifetime warranties. If you didn't melt it, or run it through a shredder, you can generally at least get a free replacement.
Last I checked, even though SD cards are "cheap". Free is cheaper.
