Hacking my Pentax K to M4/3 lens adapter

Lens adapters that allow you to connect different format lenses to camera bodies can be very handy.

But they ideally need to be the correct length to maintain focus range.

I decided to try to hack an adapter that is just 1mm or so too short.

Using Pentax SLR lenses on a micro four thirds camera

Although we got rid of the majority of our Pentax gear over a year ago, I still have a few lenses.

I've finally got around to doing something about it.

BirdBox 2020: April...it's been a funny old month!

There has been a lot of traffic in our maple tree bird box during April.

 

We've seen trespassers, thieves, and changes of ownership.

So guess who our current tenants are?

Re-discover the Night Sky #2: stacking images in Gimp

Stacking time-lapse photos of the night sky allows you to create 'star-trail' images.

It is possible to get good results using Gimp by selecting the appropriate layer mode.

This post also describes how I hacked one of the existing Gimp scripts.
