Color temp shift...?

This one is driving me nuts as I've had my 700 for a long time and only recently have I been experiencing this issue. I shoot a great deal of outdoor doc footage and I've noticed as I'm moving around and shooting a scene I will see a color temp shift. Meaning, I can be shooting a subject in shadow and pan to another subject in the sun and i'll see the color temp shift during the pan...and I mean noticeably to the point when I put the footage up on a scope I can watch the phase shift.

I ALWAYS shoot manual, I always shoot in Slog, and I leave my white balance in preset and manually set that as well. I'm recording to a 7q and I do a dual record internally and the issue is on both.

I've never noticed this before, and its hard not to, so this is a recent issue. I thought maybe something got changed in my settings and I've scoured the menus looking for some "auto' setting that may be overriding my pre set color temp but I can't find anything.

So I'm not sure if it's operator error or my camera is acting funky...anyone ever come across this or have any ideas what could be causing it I'm all ears.
 
I am not sure what the problem is, shadows have a different color temperature than a subject in the Sun.

Do you have footage to share to demonstrate what you see?
 
Yea...you might be just seeing a difference between 6000 and 5600...or 5600 and 5000, etc.

The same color temperature (even outdoors) won't work for everything. It may change from the shadows and the sun and the clouds and the surrounding colors...hour by hour.

If you wanted to be meticulous, you'd manually white balance every single time and you'd most likely see a difference in your color temperature as you/the camera moves around.
 
Yes...realize that the color temp will change from shadows to sun, but not like this. I have an Fs7 as well and I'm shooting the same type of stuff and I don't see the shift like I'm seeing in the 700.
 
Well, it's probably one or more of three things...

(1) User error (some auto setting is enabled/disabled between the cameras).
(2) Mental (your eyes are playing tricks on you and/or you're getting better at what you're doing and realizing this shift in the older camera).
(3) The camera is breaking down.

If you (a person in general) ever use more cameras, you'll see/learn how they may drastically differ in how they handle white balance and lighting.

Nothing else to consider I assume?

Same situation, these two grabs are from the same clip and about 5 seconds apart...exterior light did not change in any way shape or form...but again, my color temp did.
 
This is from the FS7 and FS700? If so...they are two different sensors that process the image differently. They will never 100% match without diving in deeper and doing some work (in camera and/or post).

If they are both the FS700, are both recording externally?

---

If the same camera is producing these results and you're just showing clips a few seconds apart...it's definitely an auto setting or a malfunction.

Are you absolutely sure the camera is not on auto white balance? Sometimes it can ride the auto white-balance in ways that are a bit buggy, similarly to how auto-focus can sometimes ride the auto focus in buggy ways. Sometimes just those leaves moving and getting darker and if shadows are cooler the auto white-balance will want to warm up the image in response.

But if you are absolutely sure it's not on auto, then I'd say it's probably faulty equipment.
 
I just saw your notes below the pics.

So it's the same camera a few seconds apart, right?

If so, it has to be either an auto setting or the camera is breaking down.

You tried recording internally and externally, right? Same result?

Same deal, two grabs from a single clip about a second apart...lighting did not change, camera did. Again, I run a manual color temp...in my way of thinking this shouldn't be happening and it seems somewhat random because the clip prior and after the above was clean.

So...this has nothing to do with me "getting better" or "not having used more cameras" rather, it has everything to do with the camera I'm using, and the behavior of said camera. In my way of thinking manual is manual and the color temp should not be shifting within a consistent scene...so I'm going to go with something wonky with the camera and perhaps the next step is to contact Sony.

However, if there is anyone else out there who as experienced this issue...again, I'm all ears.
 
These screen shots came from the FS700 recording to a 7q, I did a dual record and the internal recording is also the same. I have my camera in preset...and then manually go into the preset menu and change the color temp. I just starting noticing this behavior a few months ago. I split my time shooting with an Fs7 and I have not seen the same behavior shooting the same type of content. It is also odd that some clips before or after are fine and I'm shooting the same thing...tells me something is wonky.

Or maybe its a setting, just not sure what over rides "manual"

I mentioned that as a possibility before you provided us with specific samples of what you're seeing. Usually the above is relevant in many situations, but not in this case as we now know more and see what you're seeing.

Just to be clear again...you're pressing record and then stopping and then pressing record again, correct? You're not attempting to white balance again?

It really looks like a malfunctioning system. If no one else chimes in and helps you, my final advice before sending it off would be to try a hard reset of the system if possible.
 
All those examples are from single clips...no starting and stopping. No trying to re white balance...I run the WB of the camera in preset and adjust the color temp manually within the preset menu. I rarely, if ever, use the A/B switch. So, I hit record and for some reason during the record the camera shifts color temps. Now granted, I may do a slight pan or tilt or push...but the lighting condition with in the scene doesn't change. The sun doesn't obviously come out, or disappear ect...the scene is consistent. So it's a head scratcher...and yes, I did a system reset a few weeks ago.
 
Other things to consider...

Which lens(es)? Any chromatic aberration correction (or other) going on inside the camera? Manual lenses? Any auto color matrix setting on? Auto gamma? Any other auto setting that's maybe not related? Gain? Shutter? Is the ND filter on? I myself would try to exhaust all options/all settings/all combinations.

It's a strange problem. Like if you point the camera at a building and it starts off a bit cool then it's a bit warm, and then you cut/record again and the next clip is just cool with no changes, etc. etc. it sounds like something internally is messed up.

Plus the fact that you didn't notice this months ago is another sign pointing to malfunctioning hardware unless any internal corrections (as mentioned above) are taking place and the corrections are inconsistent.

ha, I'd be surprised...so old. But don't doubt it; recycle the sensor, change some specs and processing.

The examples shown are using two different lenses...Sony 18 - 110 & Sony G 70 - 200 f2.8 so it wouldn't seem to be a particular lens

Not that I'm aware of


Manual lenses?

I'm running my lenses manually.

Any auto color matrix setting on? Auto gamma? Any other auto setting that's maybe not related?

I'll have to really dig (deeper) into the menus and see what I can find.

Gain?

I'm shooting Slog2, 2000 iso


Shutter?

Basically no shutter...


Is the ND filter on?

Yes...1/4

Yes...that is about what is happening

Yup...I'm going to keep digging. I'm shooting again Tomorrow and Fri. I'm going to use the 7 one day and the 700 the other so we'll see how it goes but once I travel to the location this evening i'll have another look at the menus and see what I can find.

Thanks for hanging in there with me on this!
 
Try with a regular picture profile and no ND filter and manual glass, etc.

And you said this wasn't happening a few months ago? Did anyone else use your camera at any time?
