Canon EOS 550D

The iFCL metering system works well under most typical shooting conditions, producing pleasing exposures most of the time. I begin that back cutting in program, aperture-priority AE (Av), shutter-priority AE (Tv), or manual modes that the meter would work well in conditions without too much contrast, but the exposure compensation should apply if they say the sky is much brighter than the foreground, or if the accountable is dark, light, or acerb backlit. This is abundantly archetypal of multi-zone metering systems from any manufacturer.

Canon EOS 550D also accommodate centre-weighted, fractional and atom metering options for back you appetite to booty ascendancy from the iFCL system. It is worth noting that the exposure compensation range has been extended from +/- 2EV as found in previous Canon models at this level to a more respectable +/- 5EV, which will accredit added acute lighting altitude to be coped with added calmly in program, Av and Tv acceptance modes. This also will satisfy the HDR shots composite images, as it now agency that these images can be affiliated over a added ambit of exposures to ensure as abundant detail as accessible is captured.

Canon EOS 550D's Auto Lighting Optimiser promises to helps to addition detail in aphotic areas of the image, without causing clipping in the highlights. Four strength levels can be set in-camera, from off to strong. I found that by setting this feature to strong, and dialling in negative exposure compensation, JPEG could be produced with less detail lost in both the lights and shadows, all without looking washed image.

Selection of the range of automatic scene modes pre-set can have a profound effect on exposure. For example, the Landscape approach not alone applies college colour assimilation and contrast, but exposure tends to be a little darker and the Auto Lighting Optimizer is consistent with strong, helping to maintain maximum detail in shadows and highlight areas of the image, which is especially suitable for this type of images.

All the tools are there to enable accurate exposures in a range of different conditions if you know how to use them. Auto shooters will do well to ensure they familiarise themselves with the different pre-set scene modes to get the best results with the minimum of hassle.
