How much would a widescreen HDR+ picture taken with the Nexus 5 measure? topic

Since Google won't update the awful stock camera app and the quality of the pictures taken with the third party apps on the play store is garbage, I will crop my pictures using a Photoshop Script until we get a new app or I get the HTC One+/ One 2014 , to which size should I crop my pictures to get the maximum resolution posible of photos taken with HDR+ on? The Nexus 5 camera takes pictures with 3264x2448 and when you use HDR+ it takes slightly smaller pictures (3200x2368) native 8 MP cameras take pictures with 3008 x 2000 resolution, using my 3200x2368 pictures and cropping them to 3008 x 2000 won't slightly distort the picture? :confused:
