Nikon D40 vertical picture help

ISO is a numerical reference number that in film days designated the "speed" or sensitivity of the film. The lower the number the slower the film and the more light that was needed to properly expose the negative. In digital that number serves the same purpose but it relates to the sensitivity of the sensor. That is the thing that records the image . The lower the number the more light is needed.

You also need to know that the higher the number you will begin to get noise or grain in the image. So you want lower numbers outside in the sun and higher numbers inside or at night.

800 outside in bright daylight would be considered high. 200 would be a good level in daylight.

Thank you that also helps a lot!

If it's sunny tomorrow I'll try it. We're supposed to get rain all week so we'll see.

I just ordered the Exposure book from Amazon so if I"m lucky it will get here by Friday and I can read it on our long drive down (19 hours)
