Silly little photos, but what the heck, huh?? But back to the question: How have they performed?? The horizontal version has 6 sales (at SS), the vertical has 5. Looking at a more popular photo shows similar results:
In this case, the horizontal version has 13 sales (at SS), the vertical has 15... So it would seem to pay to do both versions. I've not done so well at that, it'll be something I need to remember.UPDATED: I checked my numbers more closely. I only have 5 sets of images at Shutterstock where I included both Horizontal and Vertical layouts. The sales breakdown remains pretty close. How close????
So, the logical conclusion is that we can double our sales potential by shooting both formats. While I'm sure life doesn't work quite that simply, it is clear that providing more options to our customers is smart!
