The only thing I can imagine they could do is take a shit ton of pictures, but unless you have a lot of memory cards and way too much time in your hands, it's going to be pretty difficult to make a "video" with that method.
Another option would be something like an animatic but I personally think that is too simple.
it's the most likely to be the only worth option for them. doing a classic filmatography doesn't seem like it'll work with the kind of people in the group.
I can only see them going with the thorny high road than the hole filled short down route...
Wait, is DSLR can't record video in early 2006? I only began to know DSLR after graduated from high school around 2011 so I don't really know much about it.
And also, I kinda thought the loli that Hikawa brings (from ch.7) before will joining this production. the loli really looks like Nanako in terms of their gal attire. and if somehow their hair color are similar, then it's really gets far more than I hoped for.
@Akxera DSLRs of that era didn't come standard with video recording. In fact Nikon's first DSLR with video recording would not come until 2008 (Canon following not long after).
