A couple of weeks ago Layla and I stopped by a house in Montgomery to shoot some quick pics and chat with the owner about his wonderful home. We only had about one hour to tour his house, so I had to shoot as quickly as possible.
In a perfect world, I would set up a tripod and use a low number ISO. This allows me to make the image brighter by slowing down my shutter speed. But since I was hand holding my camera, I had to use a much higher ISO number to make the images brighter. The main point I wanted to drive home today is that using a higher ISO number is completely okay. For example, I knew the pics I shot that day would only be used online, and wouldn’t be shown any larger than 600 pixels wide. When the images are that small, you can’t really see the graininess that a high ISO causes.
Here’s a closer look…
Even at 600 pixels wide the image below still looks nice on the internet. You can start to see the graininess a little on the back walls, but it doesn’t ruin the shot by any means.
If we zoom in to 100% you can see how grainy the higher ISO has actually made the image…
…so if I were shooting this photo for print, I definitely would have had to shoot it using a tripod. Magazines require high resolution images that should be as clean as possible, but if the image is never going to be blown up or printed bigger than a 5×7 don’t panic if you need to use a higher ISO!
