When your client asks for a portrait shot it is important to capture those special moments that your client will cherish for years to come.
How to get the High Speed Drool shot: simply shove a bunch of cookies into the horse, (I prefer the organic apple and oats flavor) then set your camera on speed priority and have your assistant flail around to get the ears forward. (An irish jig from River-dance works well)
Then wait for 10 to 20 minutes and you should be able to capture wonderful moments like this. (Now that I think of it, they are not big sellers, so maybe don’t put this on the cover of your portfolio)
