And even if you don’t have massive amounts of time to devote “in the field”, spend the time that you have away from the field educating yourself about what the preferred food sources are of what you want to photograph and do your best to find those food sources in wildlife management areas, federal land, parks, etc. Get on Google Earth and look at these management or other areas and look for wildlife openings, food plots, etc so you have an idea of where to go to not waste untold hours. There can be acorns all over the ground in the fall but even if there are acorns everywhere, find a good White Oak that is dropping and that's where the deer or other critters for that matter will be that like acorns. Why?? Less tannic acid in a White Oak than a Red or Pin Oak, less bitterness, better tasting acorn. Deer will walk past every acorn on the ground to get to a White Oak. This is just one isolated example but there is a lot you can learn about what animals prefer to eat to help maximize the time you do have when you head out! And educate yourself about how topography affects animal movement and identify ideal topography on Google Earth or a phone app.
Hunting, fishing, wildlife photography, it's always about finding the food to maximize your chances of success. Have fun and keep at it!
