Macro Photography

Cool. Most macros I've seen are shot with 100mm f2.8 lenses and they look similar, so forgive my lack of judgement

Longer focal length gives you shallower depth of field at the same aperture. For example, on a 40D, at 70mm f/5.6, you have 4.08cm DOF at 1m focus distance. At 300mm f/5.6 you have only 0.17cm.

This is, of course, a hypothetical example, assuming a 70-300mm lens that can focus at 1m right through the range - not sure such a best exists.

Cool. So basically the smaller the aperture at which you're shooting (high f number), the larger the DOF? Is that correct?

Correct, assuming a constant focal length. And of course the same camera - things change when the sensor/film frame size change.

Look what came to the party, It was humongous.

Its maybe not so MmMacro, after all.

Not bad from a camcorder.

Explain some more, Exif? I love to learn something new every day
Thanks

This pretty much covers it all - http://en.wikipedia.org/wiki/Exif - its just metadata stored with the photo.

I've got a nice add on to firefox that gives exif data from right click, properties. Forget what is called, but I think its useful.

Useful to have if you're into photography. It comes built into Safari.

I use Opanda's IExif which may be what you're referring to.

Saw this critter hanging on my window today - no macro lens - just my trusty 50mm f/1.8

Dang! What the heck is that thang? Looks like a branch brought to life
Nice pic.

Dunno what it is - I think it absorbed the ugly stick it got beat with.

Nice one Bwana - you do get some really cool looking moths. Here's another interesting one:

and that thing flies?

One of these days I'll get a proper macro lens because setting the aperture is a real pain the way I do it.
