W810i Spot Photometry Pics? |

"Camera
The camera user interface does not have spotometry and autofocus with macromode like the w900i. It has the same camera user interface as the w800i which has autofocus and macromode separated. "
I read this from mobilereview.com. And I know that my w810i doesn't have this spot photometry option unlike W900 and S700. I have a s700 before so i know how spot photometry pics look like. I was playing around with my w810i camera and i noticed that the photos are like spot photometry pics.
Photo 1 - focused on the TV. Natural lighting. pic taken 5:30pm
Photo 2 - focused at the room. See how the camera adjusts well with the natural light of the room. pic taken 5:32pm
Photo 3 - another pic focusing on the TV. pic taken 5:32pm
Photo 4 - camera focused just at the side of the TV.
Does these pics prove the w810i have the ability to do some spot photometry pics?
You can do your own experimentation and post the pics here if you found anything interesting.

"SPOTOMETRY is short for Spot photometry which means the camera's ability to adjust the exposure with reference to the centre of the subject of the picture."
Only S700 and W900 has this option on the camera menu. But based on these pics, the w810i automatically adjusts the light exposure with reference to the center of focus.
Notice how the pics are? the room went dark when the camera was focused at the center (TV), considering it's a well lighted room. Take note that i didn't change any of the lighting when taking these pics.

No problem 
Now i wonder if we can have some s700 owners post some spotometry pics just to compare.

People in photography and camera community will roll on the floor and laugh their *sses off because these hilariously alien terms spotometry/ spot photometry. It has been called spot metering all these years.
Just because one mobile reviewer (or his translator) with ZERO knowledge in basic photographic terms and happen to use poor wording every mobile maniac is blindly adapting them. No need for such worship.
How many still calls camera sensor for "matrix"?
Better to read some photo related articles to avoid this kind... hmmm... |

@mark
Check out this link, or if you have an S700 or a W900, see if it says Spot Metering.
I'm not saying it's not called Spot Metering in Photography. But developers can call them whatever name they want to use to refer such function/feature.

Mate...90% of us here at this forum don't know sh1t abt certain "TERMS" as experts like you do.I for one. That's why we are here to know and learn. And its a wonderful gesture that you put forth the REAL definition of the term. But the way you "CRITICIZED" the mistake, is a bit harsh.
Nothing personal, but I too get CRITICIZED for my FALSE expertise at times. But nothing sort of this like.
PS: Thank WIKIPEDIA's and GOOGLE's for the research you've done.
CHEERS!!!

Isnt spot photometry like  -lingo for spot metering? The same way Mozilla calls RSS Feeds "Live Bookmarks"? I've always thought of it that way..
Not to go off-topic, i don't think it's spot photometry per se; could be some form of beefed-up autofocus mechanism, but not spot photometry

auto-focus i think refers to sharpness... then lighting condition is another part. ability to adjust lighting to produce good overall blend is i think goes with K750i also. ive noticed these with some firmware... and of course the now-popular FAR manager... using alterated cam drivers... we can achieve these special cam abilities.

About that auto exposure setting, even my k700 can do that. |

w800/K750 got centre weighted metering from about R1N035 firmware onwards. Before that it was average metering. Centre-weighted metering gives priority to the centre of the frame, but still averages out the whole frame. Both methods are a form of average metering.
Spot metering reads only a small point, not an average of a large area. Spot metering can be centre only, or on decent cameras the "spot can be moved off-centre or there can be multi-spot metering.
I believe W810 is centre-weighted metering not spot metering, but I may be wrong about that. Don't quote me

@max
I'll be quoting you then
Spot metering indeed only read a small point of an area. There are also other techniques like multi-spot metering for advanced camera modules. I tried to snap some close up pics directly at a flash light. Without spot photometry, it should overexpose the photo. But it isn't the case here. I got a good quality light exposure.
@Max_Q
Instead criticizing people, why don't you just contribute something more useful. btw, we don't call the camera sensor as "matrix"...For most of us, it's a damn movie! 
@rockgali and axilom
Do you mind posting some pics using your camphones(like the ones above)? I'm sure the results will be interesting
@born_dead
I guess he's part of the 10%
