The EOS-10D provides a wide range of flash photography options. The built-in E-TTL flash unit is useful for everyday snapshots, it's fairly powerful and produces no color cast. There is also an E-TTL compatible hotshoe for flash units such as the Canon 420EX or 550EX as well as an 'industry standard' PC sync terminal for use with off-camera flash or studio strobe systems. The samples below were shot within a few seconds of each other to give a (rough) impression of the differences between each and to check colour accuracy.
Settings: ISO 100, EF 100 mm Macro F2.8L, Large/Fine
|Studio strobes (1/200 sec, F11)||Built-in flash (1/200 sec, F7.1)|
|Canon 550EX Direct (1/200 sec, F7.1)||Canon 550EX Bounced (1/200 sec, F5)|
Studio setup: 2 x Elinchrom 300W strobes (1 x 70 cm softbox).
Long Exposure noise reduction / Night shots
Just like the EOS-D60 the EOS-10D carries out its long exposure noise reduction 'on the fly', this means that it doesn't need to take a second 'dark frame' exposure to subtract noise. As soon as the exposure has finished it is immediately displayed on the LCD monitor.
Typical night exposures
Below you can see a couple of typical night exposures, one at four seconds, the other at eight seconds. At these exposures the EOS-10D is very clean, no more noise than we see in normally lit shots and certainly no visible 'stuck pixels'.
Settings: ISO 100, EF 28-70 mm F2.8L, Large/Fine
|4 sec, F9.0|
|8 sec, F6.3|
The four minute exposure
This was a surprise, the four minute (actually 3.7 minutes) exposure below certainly turned London night into day (a hazy night with plenty of light pollution). However the image also contains a fair amount of 'stuck pixel' noise, far more than we saw with the identical long exposure test on the EOS-D60. That said I'm sure there won't be that many people executing such long exposures.
Settings: ISO 100, EF 28-70 mm F2.8L, Large/Fine, 222 sec, F20
