A little Nikon. D3500 or D5600. Fill in lenses. 10-20mm. 35mm. 70-300mm.

General: using too wide open an f-stop when several people appear in the frame (so only one face is truly in focus).

Film: leaving a yellow filter on a lens when using a roll of color film.

Digital: wrongly thinking I was shooting a RAW file (when I somehow had a JPEG only setting).

I try now to go through a pre-shoot check list.

D850; D500. Minimum effective focal length 450mm (ie 300mm shot as a crop sensor). Consider a back up B700 Nikon superzoom for extreme longshots. Or something similar. I have shot in Namibia, Zambia, Botswana and Zimbabwe. 16-80mm or 18-140mm Nikon on a crop body. 150-600mm Tamron on a crop or full frame body. An F1.8 prime for low light. 24, 35 or 50mm. Plus the superzoom backup. In a pinch for weight or space, you might use a 70-300mm on the crop if you had the superzoom (and skip the 150-600mm). You really need to get recommendations from your guide about whether your vehicle can go off road or trail and expected distances to animals.

You could probably get by with the D850 and a super zoom. Depends on how much your trip is weight and space constrained. Spend some time pre trip practicing with the super zoom. I find them tricky to shoot properly.

Where are you going in Africa?

Nao bar upstairs in Havana for lunch or dinner. A wider lens than 24mm for the narrow street scenes.

As to operating systems and processing software, here is a link to a write up I did on Darktable. It runs on Linux. https://www.uglyhedgehog.com/t-491823-1.html

Just fyi, here is a link to a post I did of a b&w conversion of a file shot at ISO 28,000.

My understanding is that digital noise is of two types: chroma or color noise and luminence noise. In a b & w conversion, only luminence noise is an issue. This may be why b& w looks relatively better at a high iso.

I exhibit my work for public viewing at the University of Miami, generally on the floor where I keep an office at the school of law. I have become by default the "curator" of art on various sectors of the floor. I have kept the presentation simple based on cost and volume of rotating work. Large prints on canvas, simple gallery wrap with black edges. Usually 24 x 36. Photos, black aluminum gallery frames--currently color, no mat. No spacers. These are up for less than 12 months and I change out photos, so nothing fancy. For black and white, 16 x 20 frame, archival methods mat and backing with opening a bit over 10x 15 in so I can reveal edge of film as a border.

I use the black & white presentation showing film border, plus the simple black aluminum frame (white mats) for three reasons: to imitate the majority of presentations of professional displays at the Leica store exhibits I have visited; as a bit of vanity to show off when I am shooting and developing real film; and for cost reasons-the frame size and mats I use are archival and a bargain for what they are. By keeping it simple, I not only keep costs down, but spend little time worrying over anything other than the photographs.

If I saw trends in galleries moving to silver frames (some do still) I might change that one variable. My personal experience is that, at one time simple silver frames we're more dominant. Now, I see more black. When I travel I always pay attention to the presentation in museums and galleries. I want to present simply, but in sync with current professional practices.

I often do not use the Ciesta--but it makes the bags even more flexible. I also do not mind the original clips--but for the lack of a quick release. Glad this is useful to you!

Look at Domke. An F6 should be long enough. I use a D7500 but with the shorter 70-300. The 70-200mm is almost 8 in long. The internal F6 is over 11. If not, an F2. See my link for a clip modification. The F6 is nice for it's front zipper pouch. https://www.uglyhedgehog.com/t-493653-1.html

I like that crop. I have had luck with a 10x15 print in a 16 x 20 frame if you do not mind a mat.

This may fit with the sub culture of dark tourism. It is a thing now to visit places of tragedy, pain, etc. I suppose different sites serve different purposes. Some are natural disasters, some cruelty by man against man ( whether due to ignorance or design), some related to war, etc. But if you think about it, many tourist sites qualify.

When I went to Zagreb I took a 28, 50 and 90mm. In a few cases, I wished for a wider lens in narrow street areas. The 24mm would be close. I now take a wider lens with me as well. A 21mm typically. I would take the 24-105 and a fast prime-35 or 50mm. I do not know the Canon system, but if you are looking to make a lens purchase, maybe a manual focus 15, 18 or similar ultrawide. I would skip the tripod.

Exactly my inclination. D5600 is a great travel size. I do better and have a better time when I use what I am used to, and do not mix cameras and systems. Maybe a wide and a normal. Or an 18-140mm and a 35mm 1.8 dx. Add a 10-20mm if you like Ulta wide.
