white dots in the sky??

Henry Berkins , Feb 23, 2007; 09:08 p.m.

here we go again.......

ok soo, was out shooting today with my hassy, D50 as a light meter.

the usual setup for something to happen to the sensor. of course.

so i dunno, but the photogods were in my favour today and granted me sharp digital images. hopefully the 6x6's turned out the same.

but i got white spots(like white dust) in the sky..

anyone know what they are? blown pixels?

yuck, time for a new camera?

thanks *sigh*

Arrrghhh! Dust bunnies! Time to clean the sensor.....

is the white dots dust? i knew the black stuff was, but i didnt know it could be white.

Dust always generates white spots. You're getting black spots, too?

yah, here

"Dust always generates white spots."

Not true. When printing with a negative and enlarger, yes.

Edward Ingold , Feb 23, 2007; 11:17 p.m.


The spots in the uncropped image are consistent with dust on the sensor. Dust will always leave dark spots, since the digital image is positive.

It's hard to say what caused the white spots. That would occur if there were dust on a negative which was scanned. This is not consistent with your claim this is a digital image, unless the image is inverted. Bad pixels are sharply defined, not irregular like the spots shown.

Sorry, Chris, I knew it was digital, but was thinking scanned negative.

Henry Berkins , Feb 24, 2007; 01:49 p.m.

there are a number of them in the sky, like ALOT of tiny white spots, hardly noticable, and they vary from picture to picture, unlike dust which is constant.

very stange

Can you clarify? You're seeing white spots AND black spots on the same frame, taken with a digital camera?
