I would like to understand how PhotoProof handles the retina images under its bonnet.
I’ve already read the great article in the Apollo13 blog written by Daniel, but it doesn’t answer all question. As a conclusion his recommendation was resolutions bigger than 1920px make no sense. Well, but what’s then with Macbook Pros or iMacs, which are able to display 2880px and more?
At this point there is always mainly one plugin mentioned called "Retina 2x“. Based on my current understanding of how things work under the bonnet, that doesn’t add any value, as PhotoProof already automatically sends the full size image responsive, e.g. where the visitor display is able to display this. Or does it make sense to install such plugin anyway, as it enhances the PhotoProof handling, e.g. as it sends 2880px resolution just to large retina Macs, while FullHD folks will get a 1920px and all others what is set in WordPress stock image settings?
It’s not that there is a problem. I just would like to understand what is done under the bonnet (e.g. who get’s what resolution) and if there is a need or value to use "Retina 2x" plugin (e.g. by making site faster by more specific provision of the right resolution to the right device). :-)
Thanks very much in advance for some background on this.
