Hobbies

I'm a man of many interests. I like to spend my free time in active and creative way. Boredom and monotony kills me.

Photography

Photography is my biggest hobby and great way to take a break from sitting in front of a PC. Going into the field with my gear and some ideas always relaxes me and stimulates my creativity. My interest in taking pictures started in high school and continues up to this moment. I always try to learn new techniques of controlling the light and frame. Currently I'm striving to give my pictures more emotional feeling. I specialize in model photography - portraits, fashion, glamour etc.

Graphic Design

Another hobby that started way back, during my early teenage. I've been manipulating pixels passionately, trying to achieve all those awesome effects I've seen on the Internet or print ads. I've started work with Jasc Paint Shop Pro (few years before it was aquired by Corel) and later I've moved to Adobe Photoshop (starting with version 7 and moving through all CS versions up to current CS6). I've also had a short episode with 3D graphics using Rhinoceros and 3ds max, but I've felt better in two dimensional world. Interest in Internet and graphics naturally led me to learning web design and aquiring my first freelance clients.

UX, Usability

Currently I'm putting more and more interest in User Interface, User Experience Design and Usability. I believe that well-designed and easy to use applications are succesful applications, that's why I always try to make front-end of my apps as pretty and usable as possible. No big successes in this field yet, but I'm learning and trying to improve with every project.
