Viewfinder Magnifiers Review

This is a quick review of the Tenpa 1.22x magnifying eye piece for Nikon cameras.  This is also available in a 1.36x but as I have glasses they recommend the 1.22.

This was a 2nd attempt at a magnified view after a failed attempt using genuine Nikon parts.  The basics of this can be found here. Though be warned it’s harder than it looks and it’s easy to get glue on the eye piece as I found out. Continue reading

Adobe Lightroom 4 beta review

January 10th 2012 saw Adobe release an open beta of Lightroom 4, 6 years after Lightroom 1 hit the shelves.  In this period the product has changed massively but what does this new version bring to the table.

Adobe have made a few changes to existing features and also add some new ones, including a new Map module.

As stated in the title, this is a beta, so there will be dragons.  To help keep support issues down Adobe don’t let you convert old catalogues.  Instead they recommend you make copies of some files and then import and work on those, never work on the originals as they won’t be there to pick up the pieces when it all goes wrong.

GIMP startrail plugin update 1.3

I have released version 1.3 of my GIMP startrail plugin.

This is a free plugin that will layer lots of shorter exposure shots into 1 startrail.  There is also the ability to add in 1 or more dark frames which allows you to do dark frame subtraction noise reduction.

Version 1.3 adds the ability to save after each layer is added so you can do a cool timelapse of the trail building up.

This is an example startrail timelapse  I have made using this new feature

You can get the plugin from google code: http://code.google.com/p/gimp-startrail-compositor/

3 Legged Thing Kirk X2a Tripod Review

First a bit of disclosure: I won this tripod in a contest. While this may mean I can’t comment on value for money very well, I can still be objective and tell you about what I like and what I don’t.

Named after Kirk Hammet of Metallica this differently named tripod from 3 Legged Thing sits at the top of their non carbon tripod range. This one also came with the B3 Arca compatible ball head and a rather nice bag.

How long do I need to go?

I have been looking into telephoto lenses recently and been trying to find a good ballance between cost, length, lens speed and quality.

In order to do this I have made a graphic showing the fields of view of various common focal lengths to help me work out just how long I need, rather than how long I want.

Field of view of focal lengths 200mm through 500mm
