In camera metering is generally about the luminance (brightness) of light, more usually that reflected from the subject, white balance is more about the colour of the source light.

Both systems cans be easily confused, metering by light or dark subjects, by lights behind the subject etc, white balance can be confused by the colour of the subject.

Despite the 'it's subjective' crew this is why I think its impoetant to understand how the camera is working, and where it can get things wrong, as this helps you get things right.

I'm sorry, but I believe you didn't understand my question. My point is to understand the way camera works and that's why I asked the question:
Is white balance metering related to light metering or not?
So let's say that before I recompose my image, the frame is filled with some light color (e.g. 2600K) that doesn't appear in the frame once I do the recomposition (e.g. 3000K), but I locked the metering at the first frame. Will AWB change to 3000K or it will remain at 2600K even though the metering is locked? 


Is white balance related to metering?
For example I know that my 5dIII measures the exposure at the center of the frame.
Let's say I decide to measure outside of center. I than measure with center point, lock metering, recompose and refocus.
What will the AWB be? The one from the first measure or it will be recalculated after I recomposed?

I could not care less. I will NOT buy an APS-C EOS-M and I will not buy APS-C lenses for it.

I want Canon to make a FF mirrorless camera
* as small as the Sony RX-1
* with a FF sensor as good as the Sony RX-1
* with a hybrid AF at least as good as the 5D 3 AF
* with an excellent EVF viewfinder
* with wireless Canon EX-RT master built in [skip the hotshoe]
* with WiFi built in
* with a lens mount for a line of new, ultra-compact short flangeback FF-lenses with AF
* with a fully functional adapter for EF lenses
* and less expensive than a 5D 3 ... let's say USD 2500

THEN I will be interested. Until then ... I will not buy their mirrorless crap. :-)

Is it technically possible to improve the dynamic range of 5DIII via firmware update and if so how much do you think it would go?

This is really a tough question.

After some time I settled with the lenses in the signature.
I love 35L as it is a perfect walk around lens. I can do some portrait without too much distortion when I come close and I can always move few steps away to get more people in the frame.
70-200 II on the other hand gives great results and sometimes I really love the compression effect. The only disadvantage as I can see it, is it's white color. I almost bought some black stickers or sleeve for it. I'm actually still thinking about it.
85L - magic.
Sigma 12-24   ...ah, no other lens in this category, serves the purpose especially @12-16mm f8-f11 but not as good as the above mentioned.

I guess 35L is the winner here.

It would have been great had you compared Sigma 12-24 II on FF. I own one and like it a lot, especially @12mm-14mm f8-f11. 

Software & Accessories / Tripod, legs and ballhead grease - cleaning
« on: January 15, 2013, 05:20:03 PM »
Could someone recommend which grease should apply to tripod legs (lockers) once I clean them, rinse with water and dry them out? Can it be any grease or there is some that...?
Preferably some in Home Depot, Walmart etc so I could go and buy it now :-)

Do you clean ball heads as well? Mine seems to be fine for now, but eventually I guess I'll have to do that too. Is it complicated, should I give this part to some professional? The head is RRS BH-55.

...I found it that Phil Wood's Tenacious oil should be the best choice.

I noticed that too. I chAnged white balance to B2 and pics look much better for me.

Software & Accessories / Wacom Intous 5 small

I've just received a new toy. First, I must say even though it is small it is big enough for me.
I even decreased the working area on it. And using pen after mouse is such a relief.

The other thing is how to configure it.
Can you more experianced guys share your settings for Lightroom and Photoshop, please?

He he ... Thanks, for now I can justify my purchase of the 5d3

I got it today and this thing is awsome!!

The only thing that worries me is an L-plate that can acctually slide aside.
I like the way the plate for 70-200 is designed. It has security knobs at each end which wont allow it to slip aside if the clamp tightener is in the middle position.

However, very satisfied with the purchase.

Let they put some more DR too.  ;)

Thanks a lot. I believe I almost came with the final setup for purchase.

Tripod: TVC-24L
Head: BH-55 LR
Leveling base: TA-2-LB
Bag: TQB-80
Plates: L84 and B5D3

For Black Rapid lug, it will either be a Kirk you mentioned or still the option of screwing the lug direclty into the plate (not sure how safe this would be).
As I have no experience with clamps, this knob cannot be unsrewed easily, like if it rubbed against my body while walking, correct?

All in all, I'm kind of excited and I hope it will serve me well and long. :-)

Thanks, but I believe I'll go with RRS if I decide to spend this money. I still have to sleep over to see what I really need.

If I go with PCL-1 panning clamp and
would that be strong enough to hold let's say 70-200 with 2x III ?
Can Precision Plus be mounted directly on BH-55 wiht LR?

The only thing that's missing at the moment is the way to connect my black rapid to the L-plate.
I saw many options with a clamp, but for me the best way would be if L-plates screw could be replaced with black rapid ones. ...I checked in the meantime and I can see a hole with threads next to the screw
Can I screw the black rapid direclty into the plate?

I found that BH-55 matches series 2 quite well and that guys from RRS use it this way as well.
It doesn't seem any wider than the base of platform, a bit wider that the elevated part though.

I'm still considering to buy a leveling base
and a nodal slide.

I don't do panoramas so often so I still have to justify it as the price came to almost a $2000.
