you mean the "convert" command line from ImageMagick as in convert image1.tif image2.tif -average resultingimage.tif ?
I've tried this quickly yesterday and compared it with a simple but highly effective way of exposure blending in photoshop (put the two exposures on top of each other and use the sliders in the layer blending options).
Unsurprisingly, the result in Photoshop is much better, especially in the darker areas. I believe this is because of the mask that makes sure that the noise associated with the underexposed areas does not come through the end result, while the average is still affected by this noise.
So my question is whether it is possible to replicate this photoshop behaviour with imagemagick, i.e. create a blending mask in imagemagick ?
