On average how long do they take you to produce?
Good question.
Taking photos probably adds up to half an hour to game time.
Editing the photos on my phone (simply cropping, sometimes partially rotating and then auto-balancing) takes about another half hour I suppose.
Inserting them into Wordpress is easy now as it can be done with multi-selection and one click. Say another ten minutes.
Writing up the report is maybe an hour or an hour an a half (they're not long word-wise but I tend to do them in a few sections).
Note all my times are conservative. They are not typical male 'It'll only take me ten minutes to put up a shelf' times (when actually it ends up taking three hours).
So actual working time not including taking the photos in-game, maybe around 2 hours, give or take 15 mins.
Actual time taken to do that probably nearer 3-4 hours allowing for cups of tea, accidental fuck-ups, being distracted, etc. But it's something I like doing as it's a permanent record of the games for me. And hopefully some other people find them of amusement/interest/possibly even inspiration also.
It beats painting, putting up shelves or staring at the walls, drooling . . .
