I’ve enjoyed some fantastic sets this weekend – you guys have been busy and creative.
This post is about how (not) to get it right with a flash and a wide-angle lens. Actually, I was testing a gelatine to correct for tungsten lighting. The challenge was make sure that what an interior decorator friend calls the ‘delicate saffron’ colour of my walls not look like putty without blowing out the highlights in the light on the left and retain the colours off the book spines, carpet and lilies. Basically, make the viewer believe I didn’t use a flash.
I know, I should definitely get out more.
I use my bookcase for testing corner and centre sharpness of any new lens I buy, which I strongly recommend you do too, unless you’re happy with the kit lens your camera manufacturer foisted on you. There are several advantages: you can show the vendor undeniable proof you were sold a dud. Reputable camera stores have an instant return/trade policy. Also, showing a picture of books might make the vendor think you can read and are therefore less likely to conned the next time (I can hope, can’t I?).
I’m reasonably pleased with the results and would appreciate your technical comments (given the constraints of Photoblog’s colour mapping). The end result was not colour-corrected. I merely sharpened the image and fixed the edge distortion created by my lens. In continuing my act of contrition, I’ve posted some of the duds here [photoblog.com], appropriately enough under 1 April.
So, techie stuff: I used a Canon 5D mark II, which doesn’t have fill-flash. I bounced the light off my rather high ceilings, compensated at -2 FEV, used gelatine to correct for tungsten, second-curtain synch (the flash fires just before the shutter closes, not when it opens). Exposure was ½ second, f/6.3 @ 100 ISO.
