Image Gallery

Here I have collected some of my imaging attempts. I’m reluctant to say that I have “organized” them, but that is the intent.

Technical Information 

Image sizes have been selected to fit inside a box 800×800 pixels.  The side effect is that your display needs to be at least 1024 pixels wide and will work better with larger sizes.  Due to a current (as of 2006-09-05) limitation of the gallery management software, the actual images inserted as their original size and shrunk by your browser.  That means the download to your browser is longer than it should be.  Clicking on an image will, in general, take you to the photo gallery of which that image is a part.  From there, you can view different versions/sizes of the images and download them as well.  If you wish to use any of my images in your own collection, please see my copyright page.

Truncated (large) images in Gallery2 — not!

I was having a problem on with using Gallery’s image block which requires loading PHP code . It would usually work just fine, but for some reason, the image was occasionally truncated. Since I have access to the backend, I could look at the raw file and knew it had uploaded just fine. Turns out …

Finding C/2023 A3 in October from Bay Ridge

Back in October, this comet made an appearance first in the morning sky (though weather and circumstance prevented me from seeing it then), then in the evening sky. Finding this comet to take pictures was a challenge from Brooklyn. Anything astronomy is a challenge from Brooklyn. The first day with reasonable weather to see it …

Bay Ridge Regional Science Lab Proposal

Tonight I attended a community meeting where the main topic of new business was a presentation by Thomas Greene, formerly a teacher at Fort Hamilton High School here in Bay Ridge and now an adjunct professor at Kingsborough Community College, part of the CUNY system. The sad part of the proposal is that is is …

G2Image Hacks

After a bit of work, I’ve been able to hack the Drupal G2Image module to allow inserting full-size images. This isn’t exactly what I want, but it is better than inserting thumbnails. The problem with thumbnails is they look like crap when scaled up. The problem with full-sized images is that they end up being …

Scutum: The Shield

Scutum

Object: Scutum
Location: Narrowsburg, NY
Observer: Roland Roberts
Time: 10 Jul 2002
Camera: Pentax K1000, 50 mm f/1.4 lens
Exposure: 2 x 10 min + 2 x 7 min + 3 x 5 min at f/4
Film: Fuji Press 1600
Processing:
PWP level adjuments on all raw images before combine.
RegiStar average combine.
PWP curve adjustments, conversion to grayscale, composition with skyline.

Technical Notes

I took some artistic liberties with this one. The silhouetted skyline is real and was actually present in this photo, but the version shown here was taken from a shorter exposure that left it unblurred. This is the view from my dark-sky location looking from the river bank in New York toward Pennsylvania; the tree-line is in Pennsylvania.

Having said that, this view is actually pretty close to what you would see, naked eye. After sitting out in the dark for several hours, the eyes become quite light sensitive and the night sky does not appear dark, especially compared to the tree line on the horizon. The only "fake" part of this is that even the tree line did not appear pitch black to my eyes.

I chose to make a black and white image rather than color because the film I used had a horrible cyan cast and basically no other colors. My conclusion is that the Fuji 1600 has 100% reciprocity failure for the yellow and magenta layers after a very short time. I'm not sure the cyan layer is really still active for the five minute exposures which were used in this composite. There is no discernible difference between the 5 minute and the 10 minute exposures which leads me to believe that the film has given up by the 5 minute mark.
