Work and re-work

Photoshop Brush Compatibility

Sometimes things do not exactly work out as planned. I created a lot of vector files that were converted to Photoshop brushes. As I try and work with open source software mostly nowadays, I did not realise there are compatibility problems with the Photoshop brushes. But alas, that was just me being misinformed, brushes from a newer photoshop version will not load in an older version, whilst Photoshop brushes created in PS7 will load fine in CS, CS2, C3, C4 as well as PSE2+. I am glad I created all brushes and exported them as EPS so the re-work was not too painful, and I am glad that now indeed we offer (free) brushes that are compatible with multiple PS versions.

Inkscape Filter Effects

I seem to be totally addicted to Inkscape. It still crashes on me every now and again, but the current version 0.47 offers sure a lot for no cost. I wrote a few beginner tutorials, which now feature on and of course on our own I have plenty ideas for more tutorials, but before I start writing them, I research if similar tutorials are published yet. One thing that intrigues me most is the use of svg filters. The filters are available since version 0.46, but only since version 0.47 Inkscape comes with some pre-sets installed. And if the whole concept of svg filters is new, examples are exactly what is needed to learn more about the Inkscape implementation. I did follow the course “digital imaging” as part of my curriculum, so I am quite familiar with some concepts – but to “invent” new svg filters will require some further research.

Adding your own custom filters

One of the good things is that it is quite easy to add custom filters to Inkscape, altho it is not so obvious. It comes down to placing a .svg file in the Inkscape\share\filters folder. The file needs only to contain the filter definitions, and the filters must have a few attributes set properly. Further to that these filters must be added to the filters.svg.h file in the same folder, to allow translation. It is all explained in the readme file that also comes in that folder – but which user would ever think of looking there ^^.

Usability of the Filter Editor dialog

Another thing is the filter editor interface. The mock-up screen in the documentation for version 0.46 shows a preview window, the actual implementation allows to enable/disable a filter with a checkbox. This immediately applies the filter to selected objects. It is workable, but it would be nice to quickly browse through the list of available filters and see a preview of the effect before it is actually applied. It would also be very usable for building new filters.

I understand how the filter editor works, and how input/output is taken to each applied primitive. The way things are done now keeps the screen very concise, but personally I feel that an interface as used in procedural shaders would gain greater understanding from the average user. If you have no idea what I mean: have a look at the compositing tool MapZone uses. MapZone is a free texture creator aimed at the 3D designer. And tho its options are quite a bit more advanced than those in the Inkscape filter editor, the way of building filters could be done similar. The really neat feature in MapZone is that it can show thumbnails of current result of operations at each node (picture of input, picture of output), which greatly improves the usability of such a tool for the novice texture (filter) builder. An alternative filter builder with similar node editing features is filterforge (tho that is not freely available).

‘nuf said. It is easy to criticise but not to participate. I am very pleased with the availability of a svg filter editor in Inkscape, and kudos to all that worked on this impressive feature. I think it is also somewhat underexposed – and that is why I am currently considering to write a further set of tutorials on this subject. Currently I am slowly building a personal library with filter effects found on the internet, as far as they are not implemented in Inkscape yet.

New Photoshop brushes created

It has been a busy weekend… beach, good food, lazing about and so on. Then Monday knocked on the door and I decided to do some more work in Inkscape.
I wanted to make an easy fringed patch and without too much trouble I got the desired result. And then I figured it would make a nice tutorial, so I am working on that.
I also experimented a bit with the different shapes and some filter settings and the results look awesome. To make it useable for another group of graphics designers I turned the pictures into Photoshop Brushes. Peek preview on this page, and available for download at tomorrow.

Vector Illustrations now also available

We have decided to also publish our vector illustrations on For this purpose we have created a new section of resources with the name “Vector Illustrations“. For now it offers the result files of the tutorials we wrote, but sometimes with a bit of a twist. For example, I made the delicate pink cherry blossom floral design also available as a sweet baby blue design. All illustrations are available in eps and Inkscape svg format and printables of 12″x12” at 300dpi – and for now – free for personal use.

Happy 2010! Free set of photoshop brushes at VSD

It has been a quiet NYE. Not much happening around here – just a bbq with friends, some music and the sydney harbour fireworks on TV. We did have some “live” fireworks too, but more of the kiddy stuff – so not too many oooohs and aaaahs.

Free set of Zodiac Brushes for Photoshop
Free set of Zodiac Brushes for Photoshop

I started 2010 by uploading a nice set of photoshop brushes to

It is a free set of hand drawn zodiac sign and zodiac circle brushes for Photoshop, all as vector images.

Brush resolution for the individual zodiac signs is about 400 pixels, the zodiac circle is provided in multiple formats up to 2500 pixels.

For grabs – again.
