|Canon EOS 450D picture styles
One important setting on the Canon is the picture styles. It is especially important to get this setting right if you shoot in JPEG. When shooting in RAW you can always adjust the picture styles afterwards using the Digital Photo Professional software that is included. Through picture styles you can change colour saturation, contrast and sharpening among other things. It's like placing a different film in your camera. It is certainly worth playing with the picture styles, for they give your photography a personal touch, They are automatically adjusted in one of the pictogram modes.
Canon EOS 450D shows little noise
A lot of attention always goes to noise. Whereas granularity was the main annoyance in the earlier days when films were still used, nowadays it is noise, the digital equivalent. The camera manufacturer can influence this though. Canon enjoy a good reputation in this field. The CMOS sensors and the DIGIC processors, the EOS 450D features the illustrious DIGIC III, deliver beautiful, nearly noise-free pictures. And so does the Canon EOS 450D. It's not until ISO 1600 that noise becomes really visible. It is present at lower ISO sensitivities too but it is not very obvious. I have to stress, however, that this sort of information is always difficult. The visibility of noise depends hugely on the picture format you're looking at. If you care for 10 x 15 cm prints only, you don't have to worry half as much about noise as when you check everything on the monitor for one 100% and love A3+ sized prints.
Excellent in colour noise & dyanimic range
Remarkable fact is the minor change of the dynamic range when sensitivity increases. Still ISO 1600 is the limit here too; the boundary between extremely excellent and excellent. When we look at the colours, the Canon EOS 450D scores very well. Colour noise is only slightly visible at the highest sensitivity and the tonal range is excellent overall. These are really impressive values. Canon certainly live up to their reputation.
Canon EOS 450D white balance
In general the white balance is fine. Only in fluorescent circumstances the auto white balance has the familiar distortion to it. You can solve this problem easily by selecting a preset white balance, or make one manually. Or you work in RAW and correct the white balance afterwards. The white balance remains almost equal over the entire sensitivity range. This is nice to experience.
|Canon 450D exposure modes
Although photo editing programs let you correct one or two things afterwards, a correct exposure is the base of a good picture. The Canon EOS 450D offers no less than four exposure modes: multi segment metering, evaluative metering, spot metering and centre-weight metering. You have to get a knack for working with spot metering as it is a very precise metering. One tiny mistake and you're off track. The multi-segment metering will be used most frequently. And there is nothing wrong with that. In most cases it works fine. How exactly is metered, is not completely clear, but there are extensive calculations made of the whole scene. It's very important for a good exposure to get the sensitivity you select working correctly with the sensor. The Canon EOS 450D that was put on the DIWA test bank only deviates clearly at ISO 100 and 200. The sensor is 15% less sensitive than the claim of the manufacturer. For ISO 400 and higher, the sensitivity is similar to the specifications with only a minimum percentage difference. A deviation of 1 or 2% is not retrievable anymore.
Canon EOS 450D kit-lens
Canon have been criticized for the first kit-lens that was included. The Canon EOS 450D comes with an improved version, the EF-S 18-55 mm 1:3.5-5.6 IS. Indeed, including image stabilization. Only the maximum wide angle mode, 18 mm shows a clearly visible distortion. Although even then, it is acceptable. Moreover, distortion can be ignored in the other modes. This is a huge step forward. Maximum aperture shows blur in the corners at all apertures.
Canon EF-S 18-55mm lens
What's striking is that the 55 mm mode shows a clear blur in the centre at maximum aperture. In the other two modes the centre sharpness is a lot better, though not entirely excellent. It's not until f/8 that it gets sharp to become blurred again at aperture f/16 due to diffraction. This means there is only a limited amount of well working apertures at your disposal. Max-imal diaphragm for a maximum depth of field does therefore not obtain a sharper picture result, on the contrary. But this goes for every lens, no matter its price or brand name. Chromatic aberration is mainly a problem in maximum wide angle, it remains very visible. You will also find this in other focal lengths although in these cases it will not be so disturbing.
