Sensor Size Cheat Sheet Update


After some discussion on dvinfo, I added the 1/2” chip size used in the Sony EX1, as well as this weird format I just heard about called 35mm motion picture film (Super 35).

Sensor Size Cheat Sheet

When preparing for my guest stint on This Week in Photography (I know, I managed to disguise well the fact that I’d prepared), I made myself a little cheat sheet for some popular sensor sizes. It occurred to me that y’all might find it useful.


The RED Mysterium sensor is very close to the size of motion picture film (Super 35), which is as wide as the full-frame 35mm SLR frame is tall. The “small” DSLR chips are very close to this size, meaning that an inexpensive DSLR can have very similar depth of field characteristics to the movies.

On the other hand, if you want to get a sense of what the DOF will be like on the Scarlet, you could do worse than to play around with a Panasonic LX2.


Here’s an image that shows how a lens of a given focal length projects onto the various sensor sizes. It’s easy to see the “crop factor” at work here, and how a 50mm that is “normal” for a 5D would be a super telephoto if you could somehow slap it onto an LX2. It takes a 35mm lens to project an image onto a DX chip that matches the Angle Of View of a 50mm on the 5D or D700. You can visualize this by imagining what happens when you move a projector closer to the screen: the image gets smaller. If you wanted the above image to fit within the DX sensor, you’d have to move the lens, which is very much like a projector, 15mm closer, making it a 35mm lens.

I'm on TWiP

I was the guest on This Week in Photography podcast #42, where we geeked out about camera sensors and complained about the megapixel arms race.

If you're new to ProLost via TWiP, you can check out previous posts tagged with Photography. You might be particularly interested in my Lightroom 2 speed session, where I compacted six minutes of photo editing with the public beta (including lots of local adjustments) into a time-lapse screen capture.

I take tons of pictures for work, but mostly for the sheer pleasure of it. My flickr feed is here, and I update it often. Lately I've been posting older images that are suddenly of interest thanks to Lightroom 2.0's local adjustments.

My cameras include the Canon 5D with f/1.4 50mm and kit zoom and the venerable Panasonic LX2.

PTLens


We have a winner! And it's been around, but the Google, she only today bequeathed it to me.

PTLens is a $15 plug-in for Photoshop and Aperture, as well as a standalone application that can be used as an External Editor in Lightroom. It's the first real-world example I've seen that shows how a standalone image-editing application can provide functionality in Lightroom 2.0 identical to that of a plug-in for Aperture.

PTLens performs a function many (read: me) were hoping to see built-in to Lightroom 2.0; the automated removal of lens distortion, with the additional option of perspective correction. I'll quote here from the comma-phobic O'Reilly Inside Lightroom blog:

There are already profiles for most any camera you’re likely to have if it’s more than a few months old because the publisher offers to make profiles for any camera for which the user will send them prescribed test shots. The PTLens folks then make up profiles for your camera and then publish them so that everyone who has the same make, model, and lenses will also have profiles. (Hint: If I were the camera manufacturer, I’d supply those tests to these guys a few days before the camera was released.) The program automatically knows what profiles to use because it gets the camera, model, lens, zoom focal length, f-stop, etc from the metadata of the file it’s been asked to correct.

Word to that. PTLens recognizes all my cameras and will now recognize my $15. Download it now and demo it on 10 images before deciding that it's well worth the price.

More like this please!

Buy Aperture or Lightroom (or upgrade Lightroom) from Amazon and support ProLost.
