Title

Coaxing Colour out of a 150mm F8 ED achromat

About this image

The ED can be encouraged to produce some spurious colour if sufficient contrast is applied. The top section has been contrasted considerably and this action has also enhanced atmospheric dispersion with obvious blue and red fringing on bright sharp contrasty features – even at 40 degrees altitude!
