Earlier today my friend and fellow photographer posted a link to a craigslist ad from a woman in Seattle looking for a wedding photographer. The woman was upset because she thought that $3,000 for a wedding photographer was “wack” because all we do “is hang out at a wedding taking tons of photos and editing them” and that we are “making so much money its crazy.”
I first read this post earlier today while I was running errands and my head almost exploded. I immediately started drafting a horribly mean and punishing response in my head, but by the time I got home, I realized that this is probably a common misconception and that maybe I should try to explain why photographers charge what we do for our work.

Confused about what Google’s new Photovine photo sharing app is all about? Here’s a short video published yesterday that explains the service without blinding us with hairy-chested dudes. “Instead of just posting a photo, you plant it and watch it grow.”
Aside from the fun-factor of “vines” planted for random topics, it seems like the service could be useful for spreading images of real-time news stories (e.g. protests, disasters, etc..), similar to what Twitter does with text and hashtags.
When learning about ISO, you’ve probably heard that the lower the number, the lower the noise and the higher the image quality, but did you know that this isn’t always the case? The reason is something called the base (or native) ISO of a camera — the ISO achieved without amplifying the data from the sensor. This is usually somewhere between ISO 100 and ISO 200. Why does this matter? Bob Andersson of Camera Labs explains:
We all know that using high ISO numbers results in more sensor noise. More surprising, perhaps, is that using an ISO number below the native ISO number also degrades the image.
An interesting example is that when shooting on a Canon EOS 1Ds MkII, ISO 50 has roughly the same signal to noise ratio as shooting at ISO 800. This explains why the lowest possible ISO numbers can only be accessed through custom functions on some cameras.
Reddit user MacTuitui created this simple diagram (click to enlarge) explaining the idea behind HDR photography. The first low dynamic range (LDR) taken normally with a camera isn’t able to capture much of the detail found in the highlight and shadow areas of the scene. Two (or more) photographs are then taken at different exposure values to capture a wider range (the bracketing step) and subsequently combined into a single image with a high dynamic range (HDR). Since most displays aren’t capable of displaying this full range, the image needs to be tone mapped to have its appearance approximated on LDR screens.
Put your detective hats on — there’s a photo mystery going on over at Boing Boing. Luke Mandle sent in the above photograph of his little boy, Boing Boing published it asking readers to explain it, and how there’s a fine and informative debate in the comments. Read more…
