Some information on places to send your film for development in Singapore. It is really a compilation of information from members of the groups as I do not have personal experience of using all of them.
Analog Film Lab
http://www.analogfilmlab.com/
The only lab that processes E-6 (positive slides) in Singapore. They are also the only option if you are shooting 4×5 large format film. They do C41 and B&W development too.
They do mail order service so download the order form from their website and mail in your orders. Once processed, they will mail it back to you.
Black and White Reversal
https://www.facebook.com/bwreversal/
The only place in Singapore to get your normal black & white film to be processed as slides. Only mail in service and check out the facebook page on what ISO to rate your film as.
Konota
https://www.facebook.com/konotafujifilm/ (not updated for a while)
They do C41 and B&W processing for 35mm, 110 and 120 format. For C41 processing, they offer express service (1hr) for extra fees. Their normal service is quite fast too as you can collect in the evening if you send in late morning. They do cross processing ie processing slides using C41 chemicals.
Ruby Photo
We all know Ruby Photo at Peninsula Hotel Shopping Complex. They will collect your film and send them out to other labs for processing and collect it back.
Ruby is now known as Ruby Ye Photo and has relocated to the basement (same building)
to 3 Coleman Street, # B1-20 Peninsula Shopping Centre.
