Please try putting your camera in "M" mode and just setting the meter at +2 before taking the picture. Alternatively you could be in "Av" or "Tv" and just dial in some EC before actuating the shutter. Once you've done it 2 or 3 times, it is second nature.
The whole point of using a DSLR is control. YOU are supposed to be in charge of the exposure. The meter only tells you at which settings, under the current lighting, the camera would choose to expose for an 18% grey card. It is up to you to learn something about your camera and the photographic exposure. Please stop suggesting that Canon add a "SCENE" mode to the EOS 7D. It does not need them.
I would suggest that these modes get used by very few of the people who own DSLRs that have them. My theory is, if you can afford the hobby, you will invest the time to learn it. At which point the SCENE modes become exactly what they are: a crutch to get P&S owners to take the DSLR leap, nothing more. I have been taking pictures for almost 50 years. My Brownie Hawkeye didn't have scene modes and didn't need them. I was 6 years old and I could aim and shoot. When I moved up to the SLR in 1976 I got a Yashica FX-2. I still use one, and it's descendant, the FX-3 Super 2000. Neither of those have scene modes. You HAD to understand the camera back then. OMG, I remember actually having to do guide number calculations in my head for flash exposures. They weren't always right, but that was on me, not on the equipment.
I bought my first digital SLR about 3 years ago. At first, I was taken aback by the scene modes. I could not figure out what they were for! After figuring out that the whole point of scene modes is to let the camera make decisions for you, I just started ignoring them. As do most DSLR owners. My EOS 60D has some of those useless scene modes. I wish it had 2 or 3 more user-programmable modes instead. I, and I am sure most other DSLR users are too, am in either "M" or "Av" mode 98% of the time. The only time my camera goes into "P" mode is when I let someone else use it.
If you got this far, please accept my apologies for the rant. It is not aimed at you personally. You DO have a very nice camera. I would bet money that you would be much happier with it if you would learn how to use it. If not, I'll trade you even up for my Canon A1100IS. Really. I'll even pay the postage for you. Happy shooting.
