DOF PRO works with all common graphics file formats including bmp gif jpg jpeg png tif tiff tga Support for additional image file formats may be added in the future Alpha channels are discarded as DOF PRO is meant to be used as a final pass over composited images DOF PRO works exclusively on 24 bit images 8 bits per channel 48 bit 16 bits per channel support is intended to be implemented into future updates If you see the plugin greyed out in your plugins menu you are most likely not in a compatible color mode DOF PRO is 100 multithreaded and fully capable of using an unlimited number of rendering cores This results in performance increases of up to 400 on a quad core system compared to previous versions of DOF PRO In addition DOF PRO can use up to 3GB of RAM under 32bit Windows 2000 XP Vista and up to 4GB of RAM under 64bit Windows A minimum processor speed of 800 MHz is recommended and a minimum memory capacity of 512 MB is required for using DOF PRO If at any time there is any doubt regarding DOF PRO s compatibility or functioning simply try the demo version If it works the registered version will too 3 http www dofpro com RELEASE HISTORY v1 1 Implemented preview window zoom feature v1 2 Implemented autoload depth map feature on filter invocation v1 5 New and improved Highlight preservation algorithm v1 5 New and improved Bokeh visibility algorithm v2 0 Implemented full

Threshold Determines the onset of highlights Image areas with brightness values above threshold will be enhanced in order to restore their original unclipped brightness Enhancement Controls the amount of enhancement Careful adjustment is recommended as too high values will result in white and aliased highlights Tint Color Allows you to tint the highlights This may be useful to restore color information which has been clipped away in the image The default color is set to white which contains the original highlight color information Highlight tinting works in conjunction with highlight enhancement so that as the highlight is increasingly brightened the tint color will be increasingly applied Reset Resets the Highlights parameters to default settings Grain DOF PRO supports a full feature grain rendering engine This engine allows you to add specific noise to the image in order to simulate pixel grain or to restore noise which was in the original image but has been reduced by blurring the out of focus areas A gradient strip is provided to show the selected grain characteristics Animated Press for randomized grain distribution in each frame of a sequence Monochromatic Press for monochromatic grain Otherwise red green and blue channels will each receive independent noise 25 http www dofpro com Distribution Modes Two drop down boxes are provided to specify the way how noise is applied to the image Th

It is determined mainly by the shape of the camera lens and can be best seen on out of focus highlights which assume the shape of the lens aperture A lens with few aperture diaphragm blades say 5 tends to produce pentagonal highlights whereas a lens with more aperture blades say 7 8 tends to produce rounder heptagonal octagonal highlights Ultimately a higher number of aperture blades will produce more circular highlights 9 http www dofpro com DOF PRO Artists Redrover Studios Ltd DOF PRO features numerous modes of operation to suit virtually any requirement In its most powerful mode DOF PRO uses a specified depth map to derive an accurate DOF effect A Depth Map is a greyscale image where the grey level at any given point represents the distance of the object from the camera at the same point in the original image Most 3D computer graphics applications are easily capable of producing depth maps along with the rendered image For photographic images the user has to create the depth map manually which can be greatly facilitated through the use of the filter s powerful gradient features DOF PRO can not only accept single frame source and depth maps but also animated sequences in a wide variety of file formats DOF PRO Artists Left David Bazlinton Centre Martin Vicanek Right Daniel Danrich Why DOF PRO Naturally occurring depth of field has extremely complex optical characteristics It cannot be simply
