A correct exposure in your pictures is a rellay important element; in fact if you overexpose a slide the highlights are gone irretrievably and if you underexpose a slide the image will be murky with no true black tone. No matter these problems there is a common attitute among digital photographers, they think they would be able to fix everything in Photoshop but after years they have learned that using Photoshop the image is not look as good as another one that you took properly exposed.
There are a number of tools to help you get it:
- Metering Modes - some cameras provide this tool including a multi-segment one (wide range ofexposure situation).
- Spot Metering - it produces the most accurate exposure at all.
- Handheld Meters - usually are used outdoor and are able to measure the brightness of subjects.
- Bracketing Exposures - making one shot at the exposure you think is right, then additional shots giving more and less exposure.
- Exposure Compensation - you can override the metered exposure with this tool. It is useful when you encounter and exposure situation you've previously found to be problematic.
