Last Nights Sky

2007.05.26
For some reason my pictures came out real grainy, any one know why?




im not sure about this one. photoshop wanted to auto colour it likeths









I hope i shall take some pictures today because i have just got my 1gb xD card :D so i can now take pictures in full 6mp. But the sky last night was beautiful.




The last ones are a light bulb, a torch that has been moved around whilst the camera shutter is open for about 4 seconds. and also a lighter by using the same method.

ShangriLa If you have shot these on auto, the camera would have selected a higher iso rating which would enable a faster shutter speed because of the low light level. I don't really understand how it works in digital photography but in film a faster film gave more grainy pictures. I assume that a faster iso in a digital camera also compensates in some manner, but i can't explain how exactly.

The colours in #5 are fabulous. Are you saying those aren't the colours of the sky? I know that sometimes some cameras don't accurately render the colours you saw and it may only happen with one or two colours. The cheaper cameras are more prone to this. I believe this can be corrected in photoshop but with a sunset, why bother.

skrammer you can play around with levels and saturation until you get what you want. The last one is my choice!

Abigail lovely shots

carmitage I was going to say, for the grainy effect check the ASA (ISO)
On my Canon EOS I can chose the ASA I want. The lower, the neater. Your last picture... excellent !

jimmyjw nice photo... kinda have alot of noise on ur photo...u using high iso?

dogeatery ShangriLa is exactly right. The reason it is this way on digital cameras is the same reason that an electric guitar can sound distorted: the processor is overwhelmed with information. A high ISO is much more sensitive to light so that it takes only a small amount to overwhelm it, like wise a guitar amp or speaker with a low gain threshold. It's easily fixed with manual settings, I actually make a point never to shoot over 400 ISO unless I'm shooting candles in the dark. If you use Photoshop you may find a plug-in called Noise Ninja quite useful. It also comes bundled with the Bibble software (bibblelabs.com). It's easy to forget to set ISO on my camera because of the menus I have to navigate...

Didier Very nice pics !
Reg. your question on #1, like stated by ShangriLa and Dogeatery, the grain is probably due to high ISO speed. With Canon DSLR, you have reasoneable grain upto 800 ISO.
Personaly, I use DXO to manage grain at 1600/3200 ISO.
