daddyDave- so sorry about your health concerns- it certainly does bring perspective and focus, much like a camera can/did!
Is the MarkIII still available for sale?

I know I am behind the posting on this and you may have found what you need however, I am also very proficient in editing as well as family/wedding portraiture.
You can see my work (which includes what you asked) at: www.maurakphotography.smugmug.com

I have been using smugmug and it is simple to navigate and you can set your own prices, lock down folders, preview orders etc. I googled "smugmug discounts" and found a $75 off coupon when I began. Check it out!

if you have photoshop you can create a layer and copy and area and try to faze it in over the post.
