If you have the time and patience to keep moving the umbrella stand, then it would be good. I guess it depends on how many photos you plan to take in a day. There are times I wish I had a stand because I need to get in an awkward position to take the photo and having the umbrella in one hand or held with my elbow just doesn't work.
The white one I have is a 33" photography umbrella. It works but I want a larger one with a handle like my black one. I'm assuming it is what is considered the golf umbrellas; you can fit 3 people under it.
I do try and make sure that the area around/behind the daylilies don't have a lot of stuff in it like old mushy blooms or someone's feet
or what have you. In the hybridizing area it can get tricky not having the plant markers in the photos since they are the PVC pipes.
If I didn't have all the other daylily chores to do I could spend more time on the photos, but I mainly take the photos so I can have one for my files and of course now so I can add them to the database on here. Never enough hours in a day.
One thing that is helpful is to take several photos of the same bloom just in case one is blurry. Sometimes in my screen on the camera it looks in focus and my in focus green box is there, but it may not be when I put it on the computer. I used to only take one then have to run back out to take another if it wasn't too late
