What’s the deal with ISO?

Chris Lane / Camera parts, photography / / 0 Comments

In short, ISO is the sensitivity of the film or digital sensor.

To give you the best example of what changes in ISO does to a photo, I made a chart below. Using a ribbon origami rose that I made, these photos are taken with a Canon 40D, so different cameras will have different results. The large picture at the top is taken at the lowest ISO of 100 to show what the entire picture is. Below that I have images of each ISO setting at 1/3rd increments. These are 100% of the pixel size right out of the camera. For each ISO change I had to also change the shutter speed. The aperture was the same in each at f/5.6.
At the beginning I have the two extremes of the highest and the lowest next to each other to show the dramatic difference. Then at the very bottom that full photo is taken with 1600 ISO. The reason I did this is to show, depending on the use (here being the web), a high ISO will still be a suitable option. At this small size on a website, the noise is barely noticeable. But blow it up to a 16×20 print and the difference between them will be quite intense. I very rarely would use 3200 ISO, and isn’t really native to this camera (thus the H). But it is nice to have available in a pinch.

So what is it all about then?

Cameras for Christmas!

I hope everyone had a wonderful Christmas this year. I was very pleasantly surprised at the gifts that I received from my wonderful wife, Melissa. She knows that I love old things, antiques and the like, and cameras in particular. So for Christmas she got me not one, but three antique cameras. Two of the cameras are still film cameras and one is a movie film camera. I did a little research on them and took some photos to share below. And you can believe I will definitely attempt to take some photos using the cameras in the future, as well.

Flash

I tend to ignore the flash that is prebuilt into the camera. All P&S cameras have a built in flash. Not all flash is good though. Most P&S cameras have a fixed flash. In other words, it is close to the lens and points forward and unchangeable. The problem with straight on flash like that is that it is terrible for

Resolution

Resolution is typically the biggest selling point for cameras in any category. Just because a camera has a higher resolution, doesn’t mean the camera is better, though. One thing to take into account is what you plan on doing with your pictures after you take them.
A higher resolution can print to a larger size,
