My last submission of Straight and Twisted to the IPA won an Honorable Mention in the Professional Category - Trees. I remember agonizing over what category to use, Professional or Non-professional. I figured I'm a professional now so I went for it. This is a huge competition with hundreds of awards, so I'm careful not to be too excited about this, but it's good for the ego to be selected once in a while. I have my share of rejections for sure! The exercise of submitting and keeping your work in a form where you can efficiently submit is a good practice. I'll do 3-4 submissions a year if I feel my work fits well in the call. IPA is great in that there are categories for everything, and you can spend a fair amount of time looking at some great photography from previous winners.
