Just a quick testimony to old Pentax primes…   This is a quick comparison of center and and edge…   ( Click on the images to see them full sized. )  First here is the target:

Luck Shots & Image Stacking

Sunday, January 15th, 2012

I often see people stacking small numbers of photos in an attempt to improve image quality.   Sometimes this works as expected, and other times…. not so much.   One of the major issues with this technique is that it can actually yield lower image quality when the individual frames are subject to atmospheric distortions or occasional vibrations in the camera and mount system itself.

Do you know what I am?

Thursday, January 12th, 2012

One of our profs gave me one of these, then one turned up in the DPR Pentax SLR forums.     Confirming my theory that some thing spread like viruses, and some like a fungus.   The latter being the “yesterday I was unaware they existed, today they are everywhere” emergency pattern.

Pentax K-5 Time Lapse Guide

Thursday, January 5th, 2012

Overview

The Pentax K-5 is an extremely competent camera, and offers an APS-C sensor with best of class low light performance.   As is typical with Pentax, there are many in-camera processing and shooting features which can be used in combination, maximizing the flexibility of the K-5.   The K-5 includes 3 axis image stabilization, in camera HDR, flexible bracketing, in camera LCA and geometric distortion correction when used with Pentax lenses.   It makes an excellent instrument for time lapse work for a number of reasons, but it also presents some difficulties which can make it somewhat more difficult as well.   The aim of this guide is to cover these features broadly and how these fit into the usual aspects of time lapse.

Fractal time lapse outtakes

Sunday, November 13th, 2011

Sometimes I get some spurious shots while setting up a time lapse shoot.   Here are a couples that looked sort of interesting.

Abraham Lincoln – Tough Love

Abraham Lincoln letter to John Johnston.Washington, DC – 24 December 1848 

Abraham Lincoln — to brother Johnston about lending him money.

Dear Johnston:–

Your request for eighty dollars, I do not think it best to comply with now. At the various times when I have helped you a little, you have said to me, “We can get along very well now,” but in a very short time I find you in the same difficulty again. Now this can only happen by some defect in your conduct. What that defect is, I think I know. You are not lazy, and still you are an idler. I doubt whether since I saw you, you have done a good whole day’s work, in any one (more…)

If not a bomb….

I routinely travel with my home made time lapse camera battery pack.  So far the TSA has ignored it…

 

Signs of Hyperinflation

Monday, September 12th, 2011

I went to Wegmans to get some papaya from the bulk food section, and when I weighed the bag, I found the price was somewhat higher than I remember, like 100000% higher.
