Here is a list from the newest to oldest:
Luminar Neo
Luminar AI
Luminar 4

Aurora HDR is a stand alone product that can be used as a plug-in to any of the Luminar products. You only need one of the Luminar products so I suggest using Neo. Its the most current version.

I just came back from a 13 day tour of Morocco. I travelled with Peregrine Tours, a part of the Intrepid Group. It was fantastic. We travelled in a small group of 6 couples. The tour guide was experienced and gave us plenty of time to visit sites. I took photos without ever feeling rushed. In fact I took over 1400 photos. Gate 1 and others will rush you through and normally travel in buses of 50 people. Not a good way for a photographer to travel. I felt very comfortable with Peregrine and they are extremely easy to work with. I would travel with them again. Check their website and call them. its worth it. Enjoy Morocco.

Any suggestions on what lenses to pack on a trip to Morocco. I shoot with an Olympus OMD-EM1. I will be in the cities and dessert

I use it and love it.

I travel Southwest all the time. The price is great. Plenty of storage for a 21 inch carry-on type bag in the overhead compartment plus under the seat. Enjoy the ride.

I just bought an IMac with 16 mg ram and it’s fine for still photos. You can save a bundle if you purchase a refurbished Mac from Apple

I am planning a road trip and would like to take pictures of the passing scenery. What settings would you suggest when travelling at 70mph. I am using an Olympus OM-D-EM1 camera.
