I was just perusing my morning RSS feeds (the modern day replacement of reading the paper) when I noticed that Kodak had announced a couple new EASYSHARE cameras that utilize the HD format. HD has been becoming more and more popular now that HD Video cameras are getting cheap enough to fall into the hands on the ever-ready-to-spend-money “prosumer.” But I have always wondered about the format.
So it got me thinking. What’s in a format? Why is the HD 16:9 ratio so popular these days? It may be partly due to the fact that more and more people have HD televisions, or maybe it’s that new pesky iPhone thing. Whatever the reason, HD is here to stay, at least until something better comes out.
Ever since Apple introduced it’s widescreen PowerBooks computer makers have been jumping on the widescreen bandwagon all over the market. It’s somewhat hard to find a 4:3 ratio laptop these days, and speaking of 4:3, what’s the deal with the 4/3rds cameras? Out of nowhere we have yet another format.
Ansel Adams once said that the 4:5 format was the “ideal” format. He meant that it had the most appealing aspect ratio for the type of work that he did. Something like, it was the easiest on the eyes. I think the 5×7 shooter would disagree.
For years now the 35mm format (3:2) has been the king. But, I cannot tell you how many times I have had to try and explain to a customer at the photo lab I used to work for, why their group shot that spanned the entire frame in their point and shoot camera would not fit very nicely into an 8×10. Why are people who make prints so obsessed with formats like 8×10 and 5×7 and 11×14. Non of these formats are the same aspect ratio, and none of them are close to a 35mm frame.
In the digital SLR world we have all sorts of formats ranging from the APS sized sensor, all the way up to “full-frame” 35mm. The aspect ratios have usually remained the same as 35mm, but there is the crop factor which makes your lenses appear more telephoto than wide. Once camera makers reach the full-frame milestone, will the continue on, creating cameras and lenses with larger formats? Will they change aspect ratios?
The new Nikon D3 has the ability to shoot in three formats. That’s right, three formats. You can select from the full-frame 3:2 format, APS cropped format or an additional 5:4 ratio cropped format aimed at portrait shooters. But what’s the point? Can’t I still crop after the fact? Aren’t I throwing away pixels? Well, obviously the reasoning behind the APS sized format is to allow the camera to operate at higher frame rates, but what’s the deal with the 5:4?
A photo teacher I once had in college got into a heated debate with my classmates when I left the black borders visible from my Hasselblad. One side of the room argued that it was just a cheap way of showing off the type of camera you used, and the other claimed it was an aesthetic. I think I just did it because I saw other people doing it. The debate heated up to the point of arguing about whether or not it is okay to crop negatives in the dark room. I mean, the purists believe you have to crop in the camera, and you can only use a single fixed focal length lens and you have to shave your head before taking a single photo. Come on…
As for aspect ratios, it’s definitely mostly about aesthetics. Widescreen movies you find at the theaters have been really really wide for a long time, because it is a pleasing format for the audience. Can you imagine walking into a theatre to watch a movie shot in portrait? The 35mm aspect ratio is pleasing in a photojournalistic way. But so is HD. The other half of the equation is probably having to do with trends in the marketplace. HD television sets mean HD video cameras, mean HD still cameras.
Anyway, I’m just about finished with my rant. I plan to set up an Automator workflow that will quickly crop all of my images to HD, regardless of their content or purpose. That way I will be able to view them on my new TV, when I get it, in HD, low-res glory.
