Mrs LD and I went to see the Hoppe and Ida Kar exhibitions at the National Portrait Gallery in London today. Both are very good. I preferred Ida Kar but Lara was more impressed by Hoppe's work.
Hoppe's exhibition was a mixture of archive silver-gelatin prints and what were referred to as "modern prints". The "modern prints" were good but they were very starkly black and white (some were a bit too soot and whitewash, IMO) compared to the older silver-gelatin prints - which had a warmer and fuller range of tones and a fair bit less contrast.
It's a good way to spend a couple of hours but it's not cheap, though. If you volunteer the discretionary 10% surcharge so that the gallery can get the gift-aid tax back off the government, it's just over £12 ($20) per adult.
The only disappointment is that we forgot to go to see the Jason Bell "Englishman in New York" exhibition (same venue as the others) - which is free but finishes on 17 April.
