Hello fishbio. That's a neat setting. Respectfully, I think this photo is just fine for bringing back memories of your trip (I am jealous), but I don't think it's going to make it technically. The focus is on the tree trunk, bottom right, leaving the rest in a blur (I realize that the original slide must look some better). I think you would be hard pressed to recover this one. A crop and some work on shading help (more could be done than my quick and very dirty edit - which didn't transfer with quite as much brightness as it should have...), but progress is severely limited by the original information available in the photo. Keep it as a memory - it's a good one.
Best Regards,
Mark
