Macro Photography: Calvert Cliff finds

Recommended Posts

I am experimenting with my new macro lens and ring flash. These are some teeth from Calvert Cliffs, MD.

Crazy nice fossil pictures.

 

I just went to Smithsonian in DC today.

Looking good! You may also consider small tripod mounted battery powered LED lamps, and focus-stacking to get continuous focus of the tooth...

Thanks, I think the lamps are a must. Do you know of any programs other than Photoshop that you can stack photos like that?

Picolay works well, though it has a somewhat steep learning curve. www.picolay.de/

 

I've written a blog post about paleontological photography you may find interesting, here:  http://coastalpaleo.blogspot.com/2016/02/paleontological-research-tips-part-3.html

Hahahaha, loved it. I'll have to get a crack pipe full of ammonium chloride real soon. Seriously, that was all broken down really well and definitely explains the finer points of photography (and what makes a photo) way better than a lot of photography books I've seen. Thanks a lot for writing that, I'll definitely be trying those techniques as I make my way through my collection.

Very nice!  How much experimenting are you doing with different settings?  Have you tried different f/stops?  Generally when you stop down to a smaller f/stop you will get a wider depth of field, but stopping down to the smallest f/stop isn't a good idea because the effects of diffraction soften the whole image.  What lens are you using?

Awesome! I used to intern there when I was a teenager. I got to relabel their fossil collection with acid free paper and eventually they even let me air scribe a Titanosaur humerus in the prep lab . The collection there is insane.

Yeah, these were taken with some pretty poor light conditions so my F-stop was low. I've since got a lamp that makes it easier to shoot at a higher aperture but I probably need some more equipment too $$. I was using my Canon EF 100mm f/2.8 Macro USM Lens.
