High and Dry

Took the family for a picnic to "Pretty Beach" on Sunday, near Killcare on the Central Coast.

The beach wasn't so pretty, at least, I didn't think so. Calling it a beach when it's just mud flats and crabs is a bit of a stretch too :) But I did like the look of this boat.

Sony DSCP100, full auto in B&W mode.

Very artistic Mike. It sounds like the beaches north of Adelaide, when the tides out you can't even see the water. I read somewhere that shooting in B&W on a digital camera only gives 1/4 the resolution of colour because it uses 1 green, 1 red and 2 blue pixels to get each black. I'm not up to speed with digital so I don't know how true it is. If it is, maybe convert the colour to B&W in photoshop after. :confuse3:

I've worked it out Michael...it's because a picture tells a thousand words...think about :)

Jonathon: most cameras these days use red/green/blue celled ccd chips with each cell arranged in a bayer pattern. With twice as many green cells as red and blue. (Because green is in the middle of the light spectrum and we see it better than the rest)
Shooting in black and white or colour doesn't affect the resolution because the cells on a ccd chip don't directly correspond to pixels of an image. Each pixel is averaged from the surrounding cells on the ccd. Whether it then gets interpolated into colour or left as greyscale doesn't strictly effect the resolution of the final image. Taking a picture in greyscale could conceivably be made to increase the resolution though.
