Union sphere

At the Union Square, San Francisco.

After a few days' stay at Colorado, the weather of SF is too cold for me.

Madoka180で手持ち全周パノラマ撮影を開始した。前のレンズよりも視野が広いので、philopod撮影術での上下のあおりはあまり要らないと思っていたが、実際にはやはり水平に回しただけでは天頂や底の解像度が悪くなる。

よく考えてみれば、4つの魚眼で正四面体をまんべんなくカバーするなら、水平に90度ずつ回りながら、上下に(180-110)/2=35度ぐらい(つまり8mmの対角魚眼の場合よりも大きめ、45度よりは若干浅めに)あおるのがベストなはず。今後はそれでしばらく試してみる。

vitroid posted a photo:

At San Francisco International Airport, on the way to the Salt Lake City.

入国手続きの遅さ、煩雑さにはうんざり。全身スキャナーも撮られたし。

エアコンの効きすぎか、寒かった。SLCに着いたら気温37℃だったが、日本人にとってはたぶんこれぐらいの暑さのほうが快適だと思う。(湿気は全くないし)

写真はNEX-5NのHDRモード(+/- 5EV)で撮影してつないだもの。過剰なトーンマッピングもなく、いい感じ。
カメラ内で合成したHDR写真とは別に、適正露出での写真をメモリに残してくれるのもありがたい。
このおかげで、これまでと同じように、HDR版と通常露出版のパノラマを見比べて、良いほうを採用できる。

フルマニュアル魚眼+NEX 5Nでの撮影手順がやっと固まりつつある。2つ設定できるカスタムボタン(ホイールの右ボタンと中央ボタン)を駆使すれば、WBをその場で変更し、AELで露出を固定して、HDR撮影がストレスなくできるようになった。たぶんNEX-5NじゃなくてC3でも機能的には十分だと思う。ただ、今の重量級レンズを使う場合には、5Nぐらいしっかりしたグリップがないとつらい。
