Ephemeral Finnish Landscape
By K David in Pentaxian Profiles on Jan 18, 2017
Each month we pick a forum photographer with a stand-apart image in a non-contest thread. This article will allow the photographer to tell us a bit about their photo and themselves, providing a larger context to the image.
Stickl posted the first K-1 photo we've selected for this series, a fantastic shot capturing soft, morning light and fog moving through an evergreen forest in the thread Post your K-1 pictures. Thank you, Lauri, for taking part in this ongoing series and for this fantastic example of Pentaxian nature and landscape.
The Time-consuming Part

This article looks at some basic software and editing approaches related to astrophotography, including discussions about and samples of specific photos I've shared over the course of this series. Toward the end you will also find resource links for a number of excellent sources on capture and processing techniques. Note that this article is not an in-depth exploration of niche astrophotography editing techniques. Many other resources, both here on Pentax Forums and elsewhere, cover that well. Also, the niche editing techniques are not generally intended for DSLR users.

Michi Joel posted a stunning night-time photo taken with his Pentax Q7 in the thread Let's Share Shots with Q! Thank you, Joel, for taking part in this ongoing series and for this fantastic example of Pentaxian overnight and small-sensor photography.

Testing the Sony 135mm STF, and mimicing the effect on film and digital
By K David in Articles and Tips on Apr 14, 2016
You've probably heard the term "Bokeh", but have you ever heard of "Smooth Trans Focus"? Through one of our most comprehensive investigations, we describe what Smooth Trans Focus is, test a lens that delivers this effect, and most interestingly, show how this effect can be simulated without a dedicated lens.
Two SLR lenses engineered specifically to be Smooth Trans Focus (STF) offerings currently exist on the market: the Sony (nee Minolta) 135mm f/2.8 [T/4.5] STF and the Laowa 105mm f/2 [T/3.2] STF. For this article, we tested the Sony lens on film. The Laowa has very recently been launched in the Pentax K-mount for those interested in the STF effect.
This article examines what makes an STF lens special and includes several sample photos and technical examples. We'll also look at how to capture and post-process digital files to simulate an STF lens. The Minolta Maxxum 7 film SLR shows that it's possible to simulate STF lens effects with a non-STF lens on a film frame, though no technical details were provided on how it's done. Through extensive testing, we found an approach that simulates STF images on film and detail how to achieve the result.
The perfect second-camera option

An entire generation of photographers, now, has had the opportunity to capture high-quality images without using film, learning the difficulties associated with it, and adjusting for film's peculiar requirements. This installment in the astronomical photography article series looks at using film for astronomical imagery. We'll evaluate uses, challenges, and provide a list of pros and cons. If you've ever wanted to try film for astronomical photography, there are some limitations, but overcoming them is highly rewarding.
