I think you are drawing conclusions from flawed data.  If it was mostly sunshine, then your light source temperature was changing from one shot to the next.  You should try the test again under more consistent light conditions.

 

I guess I'm not understanding.. The sun never went behind a cloud, or came out from behind a cloud, during the 10 minutes it took me to do these shots. Yes, it was a little cloudy... but not so much that it would impact lighting, I wouldn't think?? And like I said, we were behind a building. The front of the building faces the sun, so we were sheltered from the sun, as the sun was setting.

 


Your WB setting seems to be mostly error, and the ExpoDisk is yielding flawed results.  As I noted above, you are sampling one light source [ light reflected from the wall ], and shooting with another light source [ direct sunlight ].  To top it off, your light source varies from one shot to the next, because of the variable cloud cover.  

 

Why do you think my WB setting seems to be mostly error? What could be causing that?

 

 


You might be able to use the ExpoDisk as a grey card at these shooting distances.  You just won't be able to use the image as custom WB image.  You will have to sample the ED in post, and use it as a WB reference.

 

 

So instead of holding it over the lens and snapping a shot from the model's position, you're saying I could possibly use it as a reference point for the model to hold, and then correct WB in post? I'll have to try that!

You are making this far more difficult than it is. Just do as Tim and I have tried to guide you.  All will be well.  You do need to bone up on basic photography.  The grey card is a great idea.  No other fancy gadgets required.


Its almost like swapping from sweet tea to unsweet tea... The change in taste is drastic... You know it's probably better for you, but it still takes some getting used to.

I'm just trying to find an "artificial sweetener" to make it somewhat more tolerable to me.


I am ordering a grey card tonight. However, I am very skeptical. Especially since I doubt the practicality of using it during shoots with children, or indoor events.. But I will try!

"I doubt the practicality of using it during shoots ..."

 

You are still missing some of the big point about it.  The grey scale card is, also, a learning tool.  Hopefully you will not need it after the learning curve is over.  However, if you find yourself in a situation where you think you might need it, you still have it.

 

For instance setting the color balance over 7000 is going to drastically change the photo.  Unless it is a pretty cloudy day. Still not good.  It is not a good trial or test.  If you want a good testing situation do it in broad daylight and set the K temp to 5200.

 

Shooting raw, which you absolutely need to be doing, there is no WB or color balance.  That is set in post.  Use DPP4 or LR or PSE to do that.

Re: Color Problem with 5D Mark 3

Hello Dusty,

 

I'm writing you just to say that you are not alone: I have the same problem you've described with my Canon 5d Mark iii. It is probably hard for other people who has Mark 3's that are working perfectly to believe this is a camera issue. But it is! I own 3 other canon dslr camera models and the mark3 is the only one with this problem. It's a nightmare. And, unfortunately I haven't found a solution...

Re: Color Problem with 5D Mark 3

You may have the problem but that doesn't mean it is the camera.  Maybe it is but let's see first.  Can you u/l a sample?  Smiley Happy

Re: Color Problem with 5D Mark 3

Hi ebiggs1, you seem do not belive in color issue 5D Mark 3.
I have using that canon camera about 1 year and struggling with that color problem very long time.

Maybe eduardohferraz can tell more what kind of problem it is.

I don't know if it is all models of 5d mk3 camera issue or only some.

I will try to give some exemples in raw files later todays afternoon and explain what is all about.

The main problem is that the photos are poor in colors and despite of the fact that histogram is fine the images seems to look too dark.

I'm surprised that only here in this forum I could find a person who were describe such a problem with 5D mark III.

Re: Color Problem with 5D Mark 3

So here there are two photos. Both are taken with Canon 5D mark 3. First one of them is not from
my camera, but from other Photographer. As you can see there is a huge difference in color
saturation between both of photos. Can someone tell me why? I know my photo was taken in other
light condition, a bit diffrent camera exposure setings, but why so huge differences. My colors
are washed out somewhere.

 

These are RAW files processed with capture one to jpg files.
Photographer: not my photo

 

Exif data:

Model Canon EOS 5D Mark III
Shutter Speed 1/4000 s
F-Number f/2
ISO ISO 100
Exposure Bias Value -0.33 eV
Metering Mode Pattern
Flash Off, Did not fire
Focal Length 50 mm
Lens Model Canon EF 50mm f/1.8 STM

 

 

My photoshoot: my photo

 

Model Canon EOS 5D Mark III
Shutter Speed 1/400 s
F-Number f/2.8
ISO ISO 100
Exposure Bias Value 0.00 eV
Metering Mode Pattern
Flash Off, Did not fire
Focal Length 50 mm
Lens Model 50mm F1.4 DG HSM Art (Canon EF)

 

There was also on the left side of the model white light reflecting surface.

 

At the end my photo retouched a bit more with capture one. You can see the colors are back but
I'm not satisfied fully with that.

 

more processed photo

 

All the best

Re: Color Problem with 5D Mark 3

First there is absolutely no way to compare these two shots.  How's this for starters?  Two photographers with unknown experience. Two different lenses. Two different post processing and unknown experience of the persons doing the edits.

 

Both shots look fine to me.  Perhaps I would have done some slightly different tweaks but they are OK.

 

You need to know, you can not view a Raw file.  It has to be converted into something else.  A tiff or probably more likely a jpg. The conversion software doesn't know how to do this so it relies on the tag file, metadata, embedded in the Raw file.  In other words it reads your camera settings and that is the starting point.  The Raw file itself is left unchanged form what the sensor saw.  The color saturation can be whatever the user wants.

The post processing is in both cases is the same. I have both oiginal raw files and just exported those images to jpg format. The is no reason to so different conversion of the Raw file. I can upload for you original raws on pm if you wish. You can see even in any viewer the difference in color saturation.

For me not, because the firs photo has better start point to post processing. I do not need to waste time for tweaking color saturation, fiddling with sliders etc.

 

So I need to know why there is the difference.

Is that lighting condition at the moment the photo was taken?

Is it the other settings in camera maybe?

 

Because I'm shooting for one year with that camera, and I'm not satisfied with what I get from it, and I need some help.

After every photo session, there is always nightmare to me getting right colors in my photos. 

So when I found the other raws files of other photographers and the same camera model as mine and I did comparation and I found there is something wrong with my raws.
