Stacking Long Exposures in Photoshop

I had an idea recently and was wondering what would happen if I stacked several long exposures in Photoshop. The result can be seen below. This picture was stacked from 20 exposures and I have to say it looks really good. So, what are you waiting for? Take several long exposures, capturing car lights or other moving light sources, open all of them in Photoshop and then stack all the layers together. Unfortunately, you will have to blend the layers individually, working on two images at a time. Select one image and then place another on top of it. Then, select the layer you want to blend in the ‘Layers Tab’ on the left, right-click on it, go to ‘Blending Options’, select ‘Lighten’ from the ‘Blending Mode’ menu and voila! Just continue stacking the layers until you get the desired effect. If you are completely new to long exposure photography please read my post on Long Exposure Photography¬†– Capturing Car Lights.

Thanks for reading and good luck with your photography.

Stereographic Projections Continued

This post is just a quick update to Stereographic Projections. If you are not familiar with this kind of photography, please read Stereogarphic Projections and Equirectangular Panoramas.

You can easily change the composition of your projections by shifting the centre of your panorama in the panorama preview window, while stitching it in Hugin. If you align the centre of the projection with the Nadir (the point where you were standing when shooting the panorama) you will get the classic circular ‘Little Planet’ effect. If you align the centre of your projection with the Zenith (the point right above the place where you were standing when shooting the panorama) you will get a reversed projection. Obviously, you may also shift the centre to other positions in order to achieve different results.
