Arrow Hey everyones

I want to ask to everyone few question about ISO speeds.

I just wonder so anybody always most using between ISO speeds of number? About 300 or 400 or 800 of ISO speeds? And, I know anybody using with manual control with camera.

Do you know what I mean?

200 - 400 dubbels the sensitivity, 5.6 to 3.5 lets 2 x the light in the lens and 1/250 to 1/500th cuts the light in half. All are adjustments that will help you get better shots. Start with ISO 200 at F 10 and 1/500 in M on a full sunny day and change it from there to get it right with the histogram. I don't know what you know so ask and some one will help.

ISO relates to the relative sensitivity to light of your film, or in the case of digital, sensor. It actually stands for nothing photographic, International Standards Organization, who, as the name would imply, set forth the standards for such things. Previously, the term ASA, named for the American Standards Association was common, and the two terms are interchangeable. A good way to think of ISO in terms of digital, is that for every ISO setting you go up, you double your sensitivity (giving you faster shutter speeds, smaller aperture numbers and therefore more dof, etc etc), while effectively halving your dynamic range. This isn't quite as true now as it once was, but obviously, shooting the lowest ISO number possible for the situation is ideal for a noise-free, color-rich image. Good luck with the new camera!

Walter,

Thanks for link and, I am will very interested how to work with ISO for of balance a while sunny or cloudy or evening or, and nights time.

Milwman,

My lens are 28-135mm. I guess so I will try my begin with ISO 200. But you know that I am so too slowly for that because I know how to change of balance with ISO numbers but how to work with F 10 and 1/500 lol

Capwell,

Oh okay umm if I use high ISO will were not too bright of color-rich?

The lens will do as the camera makes it. Just set the ISO and forget for now, AWB sets the colors to the color of the light. next set the camera to M, top dial sets the shutter speeds 500, the wheel on the back sets the lens F10 that will get you started, Now that will get you out the door. In a pinch set to TV 500 and the camera will take over but may or may not get it right.

BTW you will figure it out just a lot to set up after that its easy.

Go out shoot all you see, you don't have to shoot trains to get shots to play with. Try things and soon you start to see how it all falls together, if you stumble ask and some will try to help.

Photo shop will be a hard one to figure out, It will take time too.
