Online Lighting Diagram Creator and Strobox Community
After meeting up in a pub in London the OLDC and Strobox have decided to collaborate in order to offer the photography community the best of both tools.
Online Lighting Diagram Creator Lite
This is the original version of the Online Diagram Creator.

This is the version you need if you just want to create a diagram and generate a JPEG or PNG file. You can then use that image to upload it onto your blog or any other website. The full version allows you to link to the image or the detailed version from your profile on lightingdiagrams.com.
