FYI, the infared-ish pictures are made using the BW>Infared filter found on the PS Express app together with additional processing using the Snapseed app. After the Snapseed processing the pictures are then run through the Polamatic app with the Polaroid 600 film effect applied. The source pictures are made with the iPhone 7 Plus camera module.
iMo, the resultant pictures are more like high-key BW than infared in appearance. Though, without a doubt, there is a somewhat infared look to the pictures but I would place them at the extreme edge of the infared neighborhood, look wise. Hence, I call them infared-ish.
Whatever one might call them, I like the look and, while making them, I am having more fun than a barrel full of monkeys.
FYI, the infared filter in PS Express works best-for my intentions-with pictures which have a lot of green in them and not too much saturated yellows.
