I 've taken almost 500 images so far this week. These two are in the middle of a series taken at the West Rim of the Grand Canyon. All Images taken before, and after, are normal.

These two stand out like a sore thumb. I hope this is not the start of a failure of my EOS 5DMll

Any ideas. These are jpegs downloaded right from the camera. The top image has dividing line top to bottom and, if you look close, accross the bottom. They were separated from each other by about 20 pictures,

Woah! Wow.. Does it happen if you shoot raw? Of course I'd imagine it be another 500 raw shots to see.

Either a bad memory card, or read errors when you were downloading your pictures, possibly due to a flaky reader. Check the pictures directly on the card itself, and that will give you your answer.

This is what I think it is. I changed cards for the rest of the week and will check when I get back home.

I haven't started shooting Raw. I know I should. I've had the ability for my 50D also. I just dont have the time to post process a thousand images, or so, that I shoot at a time.

Now, if someone here will give me a compelling reason to shoot Raw along with a simple post process flow chart, I will go out and try.

Is this how images look when you review in-camera? What is the basic exif (esp shutter speed)? These look like a bad case of in-camera stitching... exposure bracketing?

Of all the images I shoot, the reality is that I keep and process only the few that standout from the rest. Sometimes finding the few good ones is difficult.

Even if you don't use RAW, using the setting would allow you to have "untouched" images especially for some more important moments. I shoot JPEG + RAW, and while I always convert from RAW, if you prefer JPEGs, you could keep using it and just store RAW... just in case.

This could, potentially, be a case where it could be your JPEG engine messing up for some reason. If you had RAW, it could help narrow down the issue.

As for work flow, I don't do too much post processing. My typical RAW conversion involves, any lens profile correction. My Sony 35/1.8, for example, needs only vignetting correction as there is virtually no distortion whereas zoom lenses typically need some distortion correction... with JPEG, the camera MAY BE doing it internally... may be is to include possible cases where the lens may be unknown to the camera which is normally not the case. With RAW conversion, a simply click of a preset would do it.

Next, I look at any need for highlight/shadow recovery or white balance adjustment. Sometimes, I will shoot Spot Metering, for example, which will generally reduce highlight detail... recovered during RAW conversion. White balance typically comes out well, but there are situations where the camera will end up confused. Having RAW helps there. Sometimes, blacks/whites, rarely (and minimally contrast... sometimes I prefer high contrast with B/W image though).

Finally, I detest in-camera noise reduction. For that matter, I'm a minimalist with noise reduction at higher ISO. Even with JPEG output, I prefer to keep my in-camera setting at "Weak" or "Off" as available. I would rather have a touch of noise in most cases than a very clean image with lost details. ISO 1600 and up, usually see a reasonable amount of NR and sharpening.

Many of these can be presets (for example, I have a preset for ISO 1600 images and ISO 3200-6400 images, based on whether it is a portrait or landscape, with mild NR in former, and a bit more in the latter, with some sharpening). Once set up, there isn't a whole lot to worry about, in a work flow.

Of course, you can play with saturation and vibrance etc, but I usually avoid those or use minimally.
