The second part of Lisa's photo tutorial http://sideoatsandscribbles.wumple.com/2011/05/24/card-photography-series-2-iso-shutter-speed-and-aperture/ is focusing on ISO (film speed), Shutter Speed and Aperture. Lisa explains that the higher the film speed, the more you can see the film's grain in the photo. I am using a SONY 3x cyber-shot automatic digital camera. The still life arrangement on my window sill was already there, I didn't try to rearrange anything for the sake of a perfect composition. I am just trying to get an understanding of the ISO function. I think that I have absorbed quite a bit of the information that Lisa has been teaching ... but it's going to take some practice! These photographs were taken at 10:00 this evening. I did not use a tripod. When I resized the photos to extra-large, I certainly could see the difference in the film's grain on the photo. There was much more grain on the window screen in the ISO 400 photo than the other settings. I liked the look of the ISO 200 photo. I apologize for not leaving the photos in the extra-large mode but they were too big for the blog.
I hope that you are joining Lisa for this tutorial, it's a lot of fun!
