I have an improved and better formatted version of this tutorial in my wordpress blog. This tutorial will cover the development of my image Milky Way from Apollo Bay using a Canon 350D, a wide angle lens, Adobe Photoshop and an image alignment program called hugin. For this to be repeatable you must be shooting with clear dark skies, free from light pollution. I used settings of Tv: 20 sec, Av: f/4, focal length: 17mm and ISO speed: 1600. A shutter release cable is also a great tool and can keep your camera clicking as it sits on the tripod. The more images taken, the better for the final result, because this will improve the signal to noise ratio that plagues digital sensors during long exposures. A tracking mount is not necessary with a 20 second shutter speed because the rotation of the night sky is undetectable at such a wide angle. Please read the following steps for more information. All images are hyperlinked to larger sizes. 1) Download this zipped folder containing four of my unaligned shots of the Milky Way. 2) Load them into hugin_0.7_beta_4. 3) Manually align images with control points – don’t automatically align. I aligned three images to a common one. Enlarge the screenshot for details. 4) Click Edit – fine tune all points. 5) Click View – preview window. 6) Click Center and Fit buttons to achieve this view. 7) Click Edit – Optimise. 8) Click Stitcher – image format – multiple tiff . Final screen before clicking Stitch Now . 9) If you don’t want to worry about learning how to align the images with hugin, then you can download this zipped folder containing the four prealigned images of the Milky Way. 10) Load each image onto a new layer in photoshop adjusting the blend mode to screen which is good at lightening images without lightening the darkest areas. 11) Add a medium contrast curves layer. 12) Add colour balance layer: shadows (-90,-25,-10), midtones (-15,-5,-20), highlights (0,-5,30). 13) The final result For comparison’s sake, shown below is a typical accompanying jpeg to a raw file I began with for one of the individual images. I used Adobe Camera Raw to extract the jpegs provided in step 1 for processing. In closing, I’d like to point out this is not the only way an image like this can be captured; there is myriads of possibilities. I have developed this simple and inexpensive method by just experimenting with the tools at my disposal. Comments are welcomed. If you haven’t done so already, please check out another tutorial I have written: Layer Masks and Transparency Gradients for The Heart.

Odin’s ravens, Hugin (thought) and Munin (memory).
July 2008 Digital painting Every morning the two ravens Huginn and Muninn, are loosed and fly over Midgard. They travel as spies across the land and sea before returning at dusk to their master Odin. They perch on his shoulders and whisper to him the events of the day. When translated ‘Huginn’ becomes Thought and ‘Muninn’ becomes Memory. The moral of the story is to pass on the memories and wisdom that we accumulate over the years. Thus preventing our stories, achievements and teachings from being forgotten. It also suggests that we should be well informed of the events of the world in order to become wise and avoid misfortune. Copyright © Mike Nash
Tenby, Pembrokeshire, Wales, UK. Taken in 2006 with a Finepix A330 pocket camera. Merged with Hugin (freebie). Several options still to try out. I am thrilled with this as it merges the colours too. Oh – and I like the warped edges! ;o) North Beach (Harbour side) / North Beach /

Tenby, Pembrokeshire, Wales, UK. Sorry – another one. Last one – promise! Taken in 2006 with a Finepix A330 pocket camera. Merged with Hugin (freebie). Several options still to try out. I am thrilled with this as it merges the colours too. Oh – and I like the warped edges! ;o) North Beach (Harbour side) / South Beach /
2 images stitched with Hugin (freebie on the net). / Harbour side of the bay. South beach is just beyond the ruins. South Beach / North Beach (opp side) /
4 images stitched with Hugin. I still haven’t really got the “hang” of this program. It all looked so simple when my son was saying – you just do this and this and this! Hm! My poor old brain! That was such a lovely holiday. I think I have convinced myself I need to go back this year. What with Tenby and a visit to Portmeirion and another to Avebury and another to Orkney already mapped out in my brain … ... ... ... ... I wish! ;o))) Well, hopefully one of them! For comparison – 2 images stitched with Hugin.
