I will be going to Tokyo this coming June and would really love to take such dreamy washed-out photos while I'm there. Please let me know what technique, camera, film/slide or accessories I would require in order to achieve such an effect!
Ermm... The photos aren't exactly what I would call great or high quality.
In any case, you can always use Photoshop to get that effect. Else, it's really a matter of deliberately degrading your image quality.
