In my last post, I introduced the sharpening process and described my first footsteps into its intricacies (yes, I had to look this one up to make sure). The study is going well, but there’s an amazing amount of information to digest. I am surprised by the number of tools available. Unsharp Mask, for example, has its roots in film photography, where wet-darkroom magicians would use a duplicate negative to create a mask to increase the apparent sharpness of a photographic print by increasing contrast along edges. From the descriptions I read, it was quite a process. Other digital sharpening tools in Photoshop include Smart Sharpen and Shake Reduction. Of course, the flip side of digital sharpening is the introduction of digital noise. (Noise is the grainy appearance of a photograph, and is beyond the scope of this blog, so we’ll save it for another day.) Lightroom and Camera Raw’s sharpening and noise reduction tools work the same way – very easy to use, and the Nik filters have Define (for noise reduction) and Sharpener (for sharpening). My head is swimming.
In a feeble attempt to keep myself somewhat sane (those who know me will attest that it’s as good as we can expect) while I’m learning sharpening, I’m still out there looking for great subjects and trying new techniques. Here’s a few pictures from the last couple weeks.
Okay, this isn’t really a new technique for me, but it’s fun and worthy of continued exploration. For this image, I overlaid a picture of the Ward Charcoal Ovens onto a picture of a wood floor (beautiful texture). I’m looking for a little constructive critique (CC), please!
This is a Merlin, and it’s the latest capture in my quest for new raptor species. (Recall that I also got a Northern Harrier and a Rough Legged Hawk this year.) Merlins are in the Falcon family, and only get to about 12″ tall with a 25″ wingspan – just a little bigger than a Kestrel. This little one was in a tree in my neighbor’s yard and, uncharacteristically, sat for me for several minutes.
My lovely bride was with me the other day and she is an excellent spotter. She saw this Great Horned Owl in a tree as we drove by. Some of my friends thought it was a Long Eared Owl, but my resident expert on bird identification confirmed Great Horned (thanks Larry!).
Because I like to explore with different filters during processing, I used a vintage colors filter in Nik Silver Efex for this interpretation. This filter is one of my favorites
Okay, this is a new technique called focus stacking. I mounted the camera on a tripod and locked it down. I took 5 images of these crabapples on a tree in our backyard, each image using a different focal plane (focusing at different levels) and blended them in Photoshop to create this image with all the crabapples in focus. I’ll refine my focus stacking workflow and use it on flowers this summer!
While I was making images for focus stacking, I made this image of an ‘about to drip’ from another crabapple tree in the backyard. When I downloaded these images to the computer, I noticed the inverted tree in pretty good focus. I tried to get closer, but I would have bumped the tree and dislodged the drip. I’ll take it for now, but will look for other drips to shoot. Aren’t optics fun?
Well, that’s it for this blog. Stay tuned for more info on sharpening, focus stacking, and macro. Until next time – enjoy!
