    Re: Colour accuracy

    Hi Jono,

    the DP1 is definitely worth adding to your arsenal in due course - when 3rd party RAW support arrives (nope, no .dng conversion available) and the price drops below £350

    In the meantime, I'm happy to be the crash test dummy for you, this time

    By the way, I *very* nearly bought a D3 + 14-24mm f2.8 a couple of days ago (saw the dpreview 30% discount tip) - but pulled back from the brink, when I considered the long term view... it would be just as much of a niche camera as the DP1 for me.

    There's just nothing to compete with 4/3rds for the long term serious photographer imho... when you consider the time & expense of collecting the right glass - the sensors will catch up with FF performance (but with dust protection that works!)

    I didn't really feel like lugging something the size of a car battery around again either!

    On the bright side, I felt great - saved myself a £3000 expense

    Kind Regards

    Brian

    Well - I've 'standardised' on Aperture now - having spent the last two years fiddling about. Which means no Aperture, no Camera as far as I'm concerned. Actually, I don't mind as long as the RAW files can be converted to DNG as Aperture now does a grand job with standard dng files.

    I'm still smarting a little from that offer - did anyone actually get one from them? (that price was far below cost). It would have been worth my while driving there - but I'd already shelled out.

    What tipped me over the edge was the D3x prospect and those two new lenses - the lenses really are very good. I have some wedding stuff to do this summer, and the low light capabilities will do that well. Assuming there is a D3x in the autumn (or even better, a D10 with the same sensor as the D3x in a case the size of the D300); then I'll sell the D3 and get that.

    I was going to get a Mamiya AF with a ZD back (like Guy), but I realised that although I'd like MF resolution, it just wouldn't suit my style of shooting.

    Well, if Olympus can make 4/3 sensors work like FF, then I'd guess that Nikon will be able to make dust protection that works

    Still, I take your point and don't disagree (My Olympus stuff isn't going anywhere).

    Actually, I don't mind that so much - what I DO mind is how people respond when you point a car battery at them - we had a dinner party the other night, and as usual I was allowed the camera for 1 minute and 15 seconds. I grabbed the D3 first, and everyone basically hid under the table . . . took the M8 and everyone relaxed and forgot about me.

    Now you can afford an M8

    Just this guy you know

    Hmmm... I'm not sure that I could get used to the rangefinder - I do like TTL OVF, and AF being available - even if I don't always use them!

    Has your E-420 arrived yet Jono? I'm keen to see some shots from the funkmaster(tm)

    Kind Regards

    Does anyone know if there is an advantage to upgrading Sigma Photo pro to 3.2 on a Mac, or are there still problems with it?

    Hi Will, Carl Rytterfalk has a fantastic Sigma promotional site here :
    http://www.rytterfalk.com/2008/04/07...view/#more-410

    If he can't convince you to upgrade, there's no hope! lol

    Kind Regards

    Cam, while you're waiting for the sun, would you mind if I sent you the X3F file... having a go at bringing these reds under control? I'd love to see what you can do?

    Re: Colour accuracy

    two quick notes before i dash off (the rain has let up a bit): first, it seems you shot this Shade rather than Sunlight (at least the file i got). secondly, a quick change to Auto WB (yes, using it after) (on Auto setting for base) without doing much else brings it damned close to the Oly colours. (sending this FYI for you try in case i'm longer than expected).

    ta.

    Re: Colour accuracy

    Hi cam,

    I took the shot in Sunlight white balance... the file I sent you had been set to shade as I wrestled to get something like the red tulips which came straight out of Auto white balance on the Oly cams.

    Please post some red tulips from the DP1, and the settings you used! I'm eager to get to the bottom of this!

    Kind Regards

    Brian

    Re: Colour accuracy

    in my brief play with the file, this was my conclusion.

    it leaned toward cyan at the expense of the reds.
    it leaned toward magenta at the expense of the greens.
    and it slightly leaned toward blue at the expense of the yellows

    there was a bit of this in everything, to a varying degree -- shadows, midtones, and highlights.. this can NOT be fixed in SPP. it needs Photoshop or the like for more advanced colour balance capabilities than what SPP can give you.

    that's not to say that i couldn't make a perfectly lovely image out of what you gave me. but if the Oly was spot on and you're after what you saw, it will take more than a little bit of grunt work.

    i will try again tomorrow to get it close (i had an emotional day today). i am speaking as an anal graphic designer here, not as a photographer, in the above comments. in many ways, i preferred what i was getting from the file vs. you Oly example. but that's a personal preference, not what the client wanted

    Re: Colour accuracy

    Hi cam,

    thanks for taking a look, and if you're busy please don't spend any more time on it... the point is that the colours were leaning all over the place!

    Strange thing is, the studio shots Sean took for his review demonstrated excellent colour accuracy - it's when you get out of the lab and into the real world that these things trip you up.

    I can only hope that Sigma can continue to improve their raw conversion algorithms for colour accuracy under wider lighting conditions - or perhaps it's simply a colour management bug?

    Kind Regards

    Brian

    Re: Colour accuracy

    played with it this morning using WB as shot. not nearly as off, but definitely different balance than the Oly (Auto anything gave it the shifts i mentioned above). the colours were more saturated on the DP1 naturally. not a bad thing, IMO. it gives you more information to work with...

    in the hands of a colour master, this could be a piece of cake, but i am definitely not that. it was a joy going back to my usual b/w, so so civilised
