Hi all,

Does anyone know of any commercial (or not) photoshop plugins that do exactly what the Maxwell Glare filter does ?

You can use The GIMP. (www.gimp.org)

On fiilters you'll find the sparkle filter...

here are a few examples...

Thank you for these links.

... it doesn't look right though. For example Maxwell would not do sparkles like that on the candle flame (a camera wouldn't do that either)

Yeah it is indeed a bit exagerated... but we don't know if it would look better changing the filter's settings. You could give it a try though it is free. This is the only filter I'm aware of.

I think on that image he used the sparkle plugin to make the glare and the supernova plugin to manually make the flairs. that's why the flairs look artificial

Although the crapy test image.. This glare seems much more natural. Using only the sparkle filter.

@ Herve: Thanks for the link... I am checking it out ... but .. it is not it :( (it doesn't do what Maxwell does)

@Markps: Thanks Mark, I will check out Gimp (have to install the program sometime). Would you know if Gimp plugins run in photoshop ?

PS. I am checking the Andromeda scatterlight .... its close ... but no cigar :(

Thomas An. - you may also want to give the RADIANCE <pfilt> command line app a try. Here is the man page:

http://radsite.lbl.gov/radiance/man_html/pfilt.1.html

Here are the specific command line options regarding star diffraction patterns:

-h lvl Set intensity considered ``hot'' to lvl. This is the level
above which areas of the image will begin to exhibit star
diffraction patterns (see below). The default is 100
watts/sr/m2.

-n N Set the number of points on star patterns to N. A value of
zero turns star patterns off. The default is 0. (Note that
two passes are required for star patterns.)

-s val Set the spread for star patterns to val. This is the value a
star pattern will have at the edge of the image. The default
is .0001.

-a Average hot spots as well. By default, the areas of the pic-
ture above the hot level are not used in setting the expo-
sure.

Thomas, I don't know if you can still buy it but have a look to the "Genesis V2 Pro" plugin for photoshop, so interesting...for me it was the best plugin for special lighting effects in photoshop.

There's an old review at:
http://www.creativemac.com/2001/04_apr/ ... o-full.htm

...the official site was http://www.futurefantastic.com , but this site has change into another business :(

I think I have the demo (I need to check it :? ), PM if you want to try it.
