digital ISO

[Ravenscroft]

currently my digital is set on auto for the ISO If I change it to something like 100 will I get better pictures for general use? I dont fully understand how it works:blushing:

The higher the ISO = more noise or grain. I shoot 100 and get excellent photos, but you may need to use a higher ISO for low light stuff if your lens isnt that fast.

Every doubling or halving of the ISO number is one stop. ISO 50 needs twice as much exposure as ISO 100 which needs twice as much exposure as ISO 200...400...800...1600...3200...

Test it out. Take similar shots but with different ISO settings. You may not notice a difference until you upload & zoom in...or when you print.

I prefer to decide what iso and not the camera.

I have been playing around with various ISO settings on my S5500, I would say the lower ISO setting the better photo you end up with.

Some example's enclosed, notice the large amount of noise and grain in the first photo, yet number 2 show's less grain and noise.

IS0 400

IS0 100

You're sort of comparing apples with oranges there andrewman. If you're going to compare two things, then you should only change one thing at a time. Here though you've changed ISO, location and lighting.

But despite that, what you said is right. lower iso - lower grain.
