Dramatic skies over pastoral scenes

Chris Lane / photography / / 2 Comments

A note, these images look like digitally post-processed HDR, and though they are definitely digital, I only used methods that I could easily replicate in the traditional darkroom for the exposure. I primarily used the same digital negative at developed at different exposures and laid them over top of each other, showing only the part that I want. I used further burning and dodging techniques. I did do some extra color correction in Photoshop, though surprisingly little. All of these photos are quite dramatic, but these are the kinds of moments that are far in between and I always run to grab my camera to hope to capture it faithfully. I’d love to hear your thoughts in the comments below and if you are interested in a print of any of these, head over to my print order page.

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?

ISO

ISO is what determines the sensitivity to light. A high number for ISO allows the camera to shoot in much dimmer light. The problem with this is that a camera will often list that it

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,

Point-and-shoot or DSLR?

When picking out a digital camera, you must eventually decide between a point-and-shoot or a so-called ‘professional’ DSLR camera. Both have a wide range of options and in this paper I intend to help you find what is best for you.
A point-and-shoot (PAS) camera is one where
