Model Canon EOS 550D + Speedlite 430 EX II
ISO 400
Exposure 1/125 sec
Aperture 5.6
Focal Length 135mm

Flash was on E-TTL II mounted on camera hot shoe (bad Ian, bad bad Ian :oops: )

PP and RAW development was done in Canon DPP.

This was the first time out with my new flash

I'm hell bent on constructive critique atm so please dive in with any of the same

Depth of Field and Focus
I'm surprised how much DoF there is on this when i look at it. Considering its at f5.6 I'd have expected the background to be more out than it is.

Looking at the histogram its fine. No blown out highlights or dark shadows where they shouldn't be.

Despite having the flash on the hotshoe I do actually like the lighting in this location. The back light provided by the circuit lighting was one of the reasons I stopped at this point and took some shots. It means that the track surface is lit, the tones are even with the E-TTL II flash metering and the action is frozen at 1/125

No aditional sharpening has been applied by DPP.

Its all very horizontal in this shot which means its not as dynamic as it could have been. just gone back and messed with the straighten tuning in Picasa and it does look a lot more dynamic when the lines become diagonal.

Colours look great, contrasty, balanced and well saturated. The blue helmet adds nicdely to the red kart and race suit. The dark grey back ground sets these off.

Its solid compositionally for what it is. All the bits are in the right places but its a simple image with simple composition.

As a bit of an additional photo story here are some other images from the evening




NB - Tara was fine, just a bit of nasty whiplash. Dont feel sorry for her, she set the fastest lap of the evening after the crash and was only put on a backboard after she's finished the race! Respect 8)

I think you timed that shot nicely and I like the framing, it shows the cart is at speed. The driver is already looking ahead to the next corner. Being able to see the eyes makes it.

Surprised that at that shutter speed it turned out as sharp as that, having said that I think a faster shutter speed would have got a much better result.

Would like to see the exif data of the photo.
With focal length of 135 and aperture of 5.6 the dof seems pretty right.

I would try experimenting with flash, make it less harsh. ie off the top of my head up the exposure by 2/3 and turn down the flash - fel by 2/3.

The flash would freeze the motion, no?

Shutter speed not so much of an issue

Oh yes. I think the maximum length of a Canon Speedlight Flash burst is 1/800 and freezing motion is one of the uses of flash.

The way to soften the light is to make it bigger as in wider and taller to soften shadows. The problem is in this case the flash is soooooo far away from the subject. Moving it closer (off camera) and using a softbox or reflector would be an option but difficult to sort out at a race track.

I want to experiment with off camera flash in this kind of environment.

The metering is done using E-TTL and seems pretty good to be honest. It could be changed using FEV +/- settings. but I dont think its needed here.

Same image as above unstraightened in Picasa

I like it

I prefer the latest one - being tilted makes it look more dynamic.
