Focusing on stars for night sky photography

Years ago I enjoyed astrophotography with an Olympus OM-1 35mm camera mounted on a 5” Celestron telescope, but only recently have I realized the accessibility of great astrophotography to anyone with a DSLR and a tripod. Night sky photography is so much easier and better now with digital cameras. If you have not discovered the wonders of the sky at night, I suggest you look at Manel Soria’s article on Landscape Astrophotography at Luninous-Landscape.com. Also Phil Hart’s eBook, Shooting Stars, provides an excellent introduction.[Read More]

Southern Utah again and again with a bit of Arizona

We only discovered the scenic wonders of Southern Utah in 2011, and we have made up for lost time by visiting there two more times since then. Our first visit was in the spring of 2011, and I reported on that trip in my post of July 11, 2011. We returned in the fall of 2011 and revisited Arches, Canyonlands, and Bryce Canyon NP’s.[Read More]

Iceland Anyone?

Iceland is only about five hours from New York, and probably offers the greatest scenic diversity in the world for an area only about the size of West Virginia. I hardily recommend Iceland for interesting vacations and wonderful nature photography. We visited Iceland in 2006 and took the Ring Rider road trip that was offered by Iceland Air. That included a car and “farm stays” spaced around the island. We saw magnificent waterfalls, geothermal areas, an arctic lagoon filled with ice bergs, and a variety of arctic birds. On top of that, there is European history dating from 870 CE, and ancient Nordic myths in the form of sagas.[Read More]

iPad 2 versus the “new” iPad: How much resolution is enough for photographers?

A great use for iPads is the presentation of photographic portfolios. Indeed the images are beautiful, and they tend to have greater impact than similar sized paper prints. Now a new iPad has been released that offers twice the resolution of iPads 1 and 2. So the obvious question is, “how much better will my photographs appear?”  To read my conclusions download the following document:

High Quality Photography Is Still All About Prints

Many of us try to obtain high-resolution images with high signal-to-noise ratios through the use of good equipment and good techniques. Unfortunately, some of our efforts are wasted when we display our images online and in small prints. It is only with 13”x19” and larger prints that high image quality can be appreciated. At some point in the future, large electronic displays will replace paper prints and will require the same high quality images now required for prints, but we are not there yet and printing is still the way to produce exhibition quality displays. In this entry I discuss what I have learned on the way to producing exhibition quality prints. It is aimed at serious amateur photographers who want to display their prints and even to sell some of them.[Read More]

Notes on scanning negatives

Some of us photographic seniors have negatives and slides that we need to digitize, and that can be a problem. In general dedicated film scanners are better than flatbed scanners for copying film, but many film scanners have vanished from the market; and the good ones that remain tend to be expensive. One alternative is to search for a good flatbed scanner that has an integrated transparency unit and make do with that. For example recent reviews demonstrate that the Epson 700 and 750 are satisfactory film scanners. I went a cheaper route a few years ago and purchased an HP G4050 scanner for prints and an occasional negative or slide. [Read More]

René Magritte, an inspiration for surrealist photographers

My knowledge of art history is limited, but I am a great fan of René Magritte (1898-1967). Magritte is described as a Belgian surrealist artist, though he claimed his work was not surrealism. In any event he was extremely original and far outside the accepted traditions of art. If you are not familiar with Magritte, I suggest that you enter “Rene Magritte images” into your favorite search engine and take a look before you read any farther.[Read More]

Is the iPAD useful for photographers?

I was motivated to get the iPad by an article in dpreview.com.  Now after using the iPad for several months, I have some comments.  It is slick, and it does some things well, but overall I am disappointed.[Read More]

Is there an eBook version of “Science for the Curious Photographer”?

This question is often directed to me. Long time readers of this blog will recall that a couple of years ago I produced and sold an eBook edition here. When SCP was sold to A.K. Peters, Ltd., I had to stop selling my eBook version.[Read More]

Update of my review of the photo sharing site, 500px.com

My review of 500px last week was generally positive, but still it did not do justice to the site. What I missed, and what should be emphasized is the importance of the concept of “community.” When some of my first uploads were only viewed a few times and received relatively few positive votes, I was disappointed. Then some of my more successful shots started receiving comments, and I was prompted to examine the galleries of the commenters. That was a revelation. I found that other nature photographers were reaching more viewers and generating higher ratings than I was with images not obviously better than mine.[Read More]

Comments on a reader’s review of “Science for the Curious Photographer.”

I welcome reviews of SCP. Reviews from experts are the most helpful to me, but I also learn from readers with different backgrounds and expectations. However, this week an Amazon.com reader listed the book as “Good but lacking” and proceeded to say that “…there is nothing in the book covering aperture or depth of field.” This is so amazing to me that I must comment.
