1) “Photographer,,” 8 and 9:21 p.m., National Geographic Channel. After triumphing with “Queens,” Nat Geo again shows it knows great photography. This six-part, three-Monday series starts with Cristina Mittermeier and Paul Nicklen, a married duo whose photos make them activists for the ocean. That’s followed by Anand Varma and egg embryo photos. Others will range from fashion to war.
2) “Dante,” 8-10 p.m., PBS; concludes Tuesday. For his final 20 years, Dante Alighieri was in exile, couch-surfing (well, castle-surfng) with supporters or neutral parties. In a perpetual civil war, he was told he’d be burned at the stake if he returned to Florence. On the move, he wrote epic poems that reshaped literature. It’s a big story t Ric Burns tells beautifully, but it’s also a long, grim journey.
3) “MasterChef Junior,” 8 p.m., Fox. “I’m the youngest of four kds,” says Lydia, who’s 9. “I’ve never been the boss of anyone.” Now she leads a five-kid team, cooking for Harlem Globetrotters (one of them a vegan). There’s some impressiive cooking (plus a few flaws) and a smidgen of great basketball, in a fairly fun hour.
4) “Shame, Blame and the Weight Loss Revolution,” 8 p.m., ABC. Oprah Winfrey eyes the surge in weight-loss prescriptions. That nudges tonight’s “women tell all” editiion of “Bachelor” back to 9, on a night overloaded with non-fiction. CBS bumps its comedies for a “Price is Right” special; it has reruns of “NCIS” (mourning Ducky) and “NCIS: Hawaii” (a prisoner plane crashes).
5) “Madame Blanc Mysteries” season-finale, www.acorn.tv. A weak season perks up slightly at the end, with an adequate episode. It starts with a well-made flashback to a gambling-room tragedy. Then a bar-owner faces a new worry, related to that night.. Things build, with some key moments at the end.
