I have been expecting it for a loooong time, as photoshop CS 5 introduced to a new era in HDR with the ability to remove ghosting and camera shake and producing sharp images from handheld brackets.
My first results show  worse ghost removal,  more noise, but much better tone maping in photomatix.

what works best for me is doing the HDR fusion in PS CS5, save a 32Bit EXR image and tonemape it with photomatix.

Note that all 3 versions have been processed with Lightroom 3. The PS CS5 version required lots more work with the sky to make it pop, while Photomatix version is almost straight from tonemaping, i only made very basic adjustments.

Made from 3 bracketed shots handheld with a 1ds3 – 24-105 lens @ 24mm f/8. 1/50 – 1/400 – 1/3200  ISO 100

we should probably wait for the final version of photomatix and test this some more before making conclusions.

I particulary like this one, you can see the bonito eggs flowing in it’s mouth while it’s feeding

Food!

Nathalie avec le Requin Baleine

Pas facile de montrer ce que l’on ressent au milieu d’un troupeau d’environ 300 requins Baleine qui nagent la bouche ouverte pour gober un maximum d’oeufs de bonite

Et une dernière silhouette du dessous juste pour le plaisir

Les meilleures images sont probablement cachées dans le disque dur de mon portable, je suis impatient de pouvoir voir tout ca tranquilement à la maison!

la semaine prochaine… photos de cenotes, prises la semaine dernière !

Very useful to see if there is dust on your sensor and if it needs cleaned
