G9

I had a couple of over-exposed shots when taking picture of person wearing black attire at night. Guess the G9 is not that perfect afterall. But a lil bit of negative compensation solved it all. All this in the Full Auto mode. But at manual/Tv/Av mode, all the exposure is ok.:think:
Heard there were issues with light leak on the LCD mostly around the lower right corner. Not sure if that would affect the quality of the Images taken. Hence I am curious if the batch thats being released here have a different serial numbers/batch altogether.
Anyone upgraded from a G7?
Apart from the 3 inch LCD, Raw file, 1.7 sensor and 12MP in the G9, hoping to hear their views on the G7. Thanks.
I don't think this is a problem specific to the G9. If you use any camera in Full Auto mode, and you shoot a scene that is dominated by dark colours, the camera's onboard AI will be fooled into thinking that the scene is very underexposed, and then proceed to compensate by overexposing it. This is why you get overexposure. You can try this with even a DSLR and you will get the same problem. No matter how the intelligent AI on the part of the camera, it can't substitute for the knowledge of the photographer.
Yes, thank you. I'm very much aware of that. :bsmilie:
Did you read my last sentence?:think:
Sorry, didn't mean to offend, but yes I did read your last sentence. I was responding to your point about the G9 not being that perfect afterall, ie maybe other cameras wouldn't have this problem. I just wanted to make the point in case other people get the impression that they can buy a good camera, set it on full auto, and expect perfect exposures everytime, and that if you don't, that means that there is something wrong with your camera.
Strictly speaking, the same issue overexposure should happen even with TV or AV mode. Only with Full Manual it shouldn't happen because the exposure control is fully in the hands of the photographer.
No worries bro.
I do see your point. And I do agree. Bottom line is, its the person behind the camera.
The camera is just a tool. But I was just kinda surprised that exposure was good on the creative zone but turned out under when on auto mode.

I agree with your statement, its the person behind the camera.
My contention is with the manufacturer; sure, we can manipulate the controls and the settings to get good creative shots, but surely in the automode, it should be able to compensate properly.
I tried to shoot the same scene with G9, then used another point and shoot, but there were no overexposure on the P&S camera. and G9 is not cheap! Took this up with Canon, they agreed there is overexposure because of the shift towards higher ISO (based on poorer pic taking with other cameras). In my view, this setting is all human. Even the canon mgr's pictures had overexposed highlights, depending on where the focus (dark or light areas) is pointed at.
I attended two training for 2 different cameras, and the instructor ask us not to use auto mode, but use other modes. Why then is the purpose of having auto mode? If the auto mode is provided, at least the manufacturers should make a good job out of it.
Hi guys.
i m new to CS.
jux check with alan and tk foto,
both offering $800 w GST + 2GB mem. card.
currently the cheapest found by me.
anyone gets a better deal elsewhere?
Please advice.
oh, and how is the noise after the cam gets a 12Mbpixel than G7?
any kind soul tried and willing to share his/hers experience ??

I have a G7 and my friend recently bought a G9. The noise levels look quite similar in my opinion.
Sorry to be a pain and keep repeating this stuff to you, but how the auto mode of a camera reacts depends heavily on what the scene you are shooting contains. Just because one camera overexposes while another exposes correctly is not conclusive proof that the overexposed one is wrong.
What I mean is that if you point both cameras at a white piece of paper and one camera underexposes (paper turns out grey) and one exposes correctly (paper turns out pure white), the one that underexposes is actually displaying the correct behaviour.
This is because the camera is not a human being and cannot be expected to know that it is shooting a piece of white paper, and that it is correct for the paper to be displayed as pure white. The camera would assume that the scene is just overly bright (ie over exposed), and hence underexpose the shot in order to compensate so that the white paper is captured as neutral grey.
The opposite will apply if you point both cameras at a piece of black cloth. In these situations, it is a MUST that you switch to manual exposure mode and do your own exposure compensation to force the camera to expose the shot the way you want it to appear, ie black cloth must appear black, and white paper must appear white.
So to conclude, you have to test both cameras within the same time window from the same angle, zoom, ISO etc at the same subject. Also, to test for true over and underexposure, you should ensure that the subject you are shooting is a neutral colour, ie not overly dominated by dark colours or overly dominated by light colours. Only if you do this, and the camera still over or under exposes, then there is something wrong with the metering. Not to doubt the expertise of the manager at Canon, but did he do the tests in this manner?
ya. read it in dpreview.com and seems like theres a batch with the blue dot at the corner problem.
The guy return the cam and got replacement set about 5 days ago. and the problem resolved.
So does anyone know how to identify which r the batch with the blue dot problem so to avoid getting those while buying ???:think:

Look up Ebay for the G7 wide angle adapters. Think they are way, way cheaper...
But I have no idea the picture quality though, best you look for some reveiws when you find them. (I've seen them on Ebay.) Good luck !
