My Favorite Simple Gimp Tricks

An overcast day is the worst sort of day for a photo guy.  The IR and the red tones are obliterated by the water vapor in the sky, and what’s left is a mono-tonish blue that uses only about a third of the pixels in your shiny new camera.  The result is often boring, but I’ll admit that creative photographers sometimes manage special photos in spite of the clouds and blue light.

Nature’s sculpture: Water Swept Grasses

Figure 1: Nature made a surrealistic sculpture, awaiting my lens

The photo in figure 1 is of water swept grasses.  Click it to see it in full size.  Nature makes some very pretty stuff by accident sometimes.  Lovely to be there to catch it.

Buggy for Bees – macro photos

 

Figure 1 : Bee shot taken with K5, Pentax 50mm /f1.4 vintage lens

Recently I started to take macro tube shots of bees in my area.  This is quite an addicting facet of photography, I must say.  I’m a rank beginner at this task, but so far have managed a few semi-interesting shots.  The picture in figure 1 is one of my favorites thus far (clicking on the photo will show it enlarged on smugmug).

K5 Quandry

Figure 1:  Should I go mirrorless?

When I first used my K5, I was enthralled.  It was easily the most solid feeling camera I’ve ever owned.  Most cameras give me the feeling that I have glass in my hand (smile) – and that I have to be careful.  The K5 made me feel like I had a hatchet in my hand and that tossing it into a spiraling arc that ended on a cleaved tree trunk would do it absolutely no harm.

Vintage Lens Honeymoon

Is Over.

Well, I kick-started my photography hobby for a second time recently after a hiatus of about 37 years. I bought into the theory that I could populate my lens arsenal with vintage stuff and save a bundle.  In short order I had over a dozen lenses in my possession, none made after the date they want to check on driver’s licenses in order to purchase hard whiskey.   Some were made not only that many years ago – but multiples of that many years.

Caveats associated with Vintage Lenses

My vintage lens collection is growing by leaps and bounds.  I have gotten some good results from some of the lenses, and in some cases I find that they equal or exceed a number of currently available (newly manufactured) lenses.

However; not every vintage lens can be used safely on every camera.  I think the old film cameras must have had larger registration distances between the mirror and the rear of the lens barrel.  Certain lenses, when they are focused at some point in the direction of infinity on the focus ring, protrude from the rear of the lens mount.

Vintage Lens Sharpness List

I’ve been collecting quite a few vintage lenses, and I consider some of them to be very good lenses, while others seem lacking.  I’ve decided to create a “Sharpness list” for these old lenses (most are older than 30 years old, and some are over 40 years old).

I should mention the methods I’m using to determine what is (at least according to my eyes) a sharp lens.   I am using an image focus comparison chart (a “fine resolution” spoked star chart), affixed to a wall, and illuminated with daylight.
