\"A<\/span>Earlier today Callan showcased<\/a> a rather cool idea first dreamed up by fellow Scibling Alex Wild at Myrmecos<\/a>: using a hand lens to shorten the focal length of the iPhone camera into the realms useful for macro photography. I had to try this out myself, so I grabbed the nearest interesting hand specimens* and got snapping. In the spirit of experimentation, I took pictures of the same field of view both with and without augmentation by the hand lens.
\nFirst up, a Neoproterozoic diamictite from Oman (part of the possible Snowball Earth sequences<\/a>):<\/p>\n

I’m rather impressed; returning to my earlier thoughts on the iPhone as a potential field tool<\/a>, a case with a bracket to clip on a magnifying lens would be pretty darned useful for quickly recording lithologies. If said case added extra battery (like this one does<\/a>) and some weather proofing, and perhaps a capacitive finger replacement a bit more elegant than a sausage<\/a>, and it could be extremely darned useful. In the meantime, perhaps further experimentation might produce images worthy of inclusion in the upcoming Accretionary Wedge geo-imagery bonanza<\/a>. Is anyone else experimenting with this?
