Initially, I thought I could order colour development kits from the USA, as heaps and heaps are available. However, they are not allow to send colour chemicals outside the USA. After a bit of further hunting, I found that the chemicals could be bought from the UK at a fair rate, at least much cheap than special ordering a kit from New Zealand.
Yes, you can send your film to a lab to get developed. Yes, it is cheaper. But where is the fun in that? And what control do you have over the quality?
I developed my first batch of colour film and I was amazed at the results. Despite reading in forums how difficult it is to develop colour film, it was not difficult at all, just more quality control is involved.
Here is a great resource from Youtube that helped me develop my first rolls of colour film.
