I don’t think I’m obsessed by grids but I am using the 3 across grid format as an integral part of my Instagram post lately. Sometimes is just posting three similar items but I do has several 1by3 or 2by3 panel mosaics in my post recently. I wonder of they confuse by viewers, (I have had a bit of a drop in followers) or is it a bit of a hassle to find the grid display.
There are actually many tools and apps like Instagrids that can help prepare the grids but they all suffer from the instagram restricted api and fact that images have to be uploaded individually from a phone or mobile device.
There are many others doing great work with grids on their instagram profiles. The biggest issue being right now. there is no common hastag or icon to indicate a picture is part of a series so the casual browser needs to recognize the photo being display may be part of a grid series and click on their user icon to get to their profile. This is not a natural action for those thumb scrollers that I notice everywhere these days. Still those in the know with a bit of time to stop and appreciate the grids there is some wonderful creativity going on
I’ve settled for the hashtags
#1by3grid #2by3grid &/or #triptych
When an image spread across several adjacent squares
See you on the grid some time soon.
