I know the plugin Hydra is available for automatically creating HDR images in Aperture. Is there a step by step guide somewhere on how to use the 3 raw files to make an HDR image without using any plugins or extra software on top of Apple Aperture?
I use PhotoMatix as an external editor. Hydra is just terrible in comparison. Its not as nice as using it as a plugin but it gets the job done. Now they just need to make it a plugin and we will be set.
