This Long Horned Beetle was photographed using the Canon EF 100mm f/2.8 USM Macro lens. I blended 6 shots which had different points of focus into a single using new auto-blend feature of Adobe Photoshop CS4. At 1:1 depth of field was minuscule. By using auto-blending I was able to acheive a perfectly clean image of the beetle with all the points in focus. I planning to present the tutorial on autoblending soon. Previously I had tried focus stacking using freeware combinez5 which produced fantastic results.
