Take any photo from your Mac and apply gorgeous filters to it | ShutterstockĮven though Instagram still doesn’t let users post photos from a computer, several apps exist that not only attempt to duplicate Instagram’s filters, but add others into the mix. Often, I have a photo on my computer that isn’t on my iPhone, and I want to be able to add nice filters and make tweaks on a bigger screen before posting it on Instagram. Despite Apple and Google’s best efforts to seamlessly keep all photos synced across all devices, sometimes it just doesn’t work out that way.
