I write here, but it x all pictures of this folder ..., the big problem of this type of photo is the focus .... which can not be anything other than manual. Once placed the hollow and mounted the mk4 connected to 400mm f2.8, I decide a point of focus that allows me to have more photos in focus as possible and then after putting the lens to f8 (the iso is 1250) point on the nest (top left edge to center) and Out autofocus and stabilization (not used on the trip), I close my eye and I get a flash 580ex to 1 \ \ 16 power. then flank attack the contact connected to a remote control and put the mk4 in continuous mode turned on (Escude the stby) and wait for the approach of the swallows to nest. To 1 \ \ 400sec. the photos are almost 2 stops underexposed but still sufficiently x public exhibition. everything else jumps out of the PP scrivo qui,ma vale x tutte le foto di questa cartella..., il grosso problema di questo tipo di foto è la messa a fuoco....che non può esser nient'altro che manuale. Una volta piazzato il cava e montata la mk4 collegata al 400mm f2.8,decido un punto di messa a fuoco che mi permetta di avere più fotografie a fuoco possibile e quindi dopo aver messo a f8 l'ottica( gli iso sono 1250),punto sul nido (bordo alto a sx-centro) e stacco l'autofocus e la stabilizzazione(non si usa sul trip),chiudo l'oculare e monto un flash 580ex ad 1\16 potenza. poi attacco sul fianco il contatto collegato ad un radiocomando e metto la mk4 in modalità accesa continua(escude il stby) e aspetto l'avvicinarsi delle rondini al nido. Ad 1\400sec. le foto sono quasi 2 stop sottoesposte ma sufficentemente ferme x l'esibizione pubblica. tutto il resto salta fuori dalla P.P.
