HD For Indies

Looks absolutely spectacular. I can't wait for the full-rez version in RAW, to really put it through its color grading paces.
 

jup, that looks nice, but how you can say something about highlight detail on a scene shot on an overcast day with no sky or reflective objects in the picture beats me.

chris -

good point, but milk bottle. Look at the big version, and note there's a highlight on the milk BOTTLE separate from the highlight of the milk.

A good sign.
 

This image is more worrying to me than impressive. It's cloudy. Take that thing into the woods on a sunny day and lets see what it can do!
 

mike,

i dont doubt the red camera will rock and i fully support your enthousiasm, the overall look of the image confirms that they are on the right track.

*however*:

- the milk highlights actually *do* blow out in the small reflections (ok, the area is so small that it doesnt look bad, but still)
- the milk bottle has weird color artifacts (and no, i dont accept "this is a low res jpeg image as an excuse.. a 2K png file would hardly tax their server)
- the whole picture has weird edge artifacts, like it would have been oversharpened and then jpeg compressed (see above)

btw, to see the real colors you'll have to open it in photoshop and assign the (not convert to) Adobe RGB profile. while i understand that jim jannard is an experienced photographer, preping a jpeg for web viewing in Adobe RGB is not a terribly clever idea as 99% of the people will see moted colors.

still, all this technical quibbles aside i'm really lookinq forward to an affordable indy camera with full size sensor and raw workflow (did the last shot on a Z1).

Chris - there's no clipping in the image - try the following in photoshop - do a levels adjustment and set the input levels to 229/0.78/255

You can see under this stupidly extreme colour adjustment that there is some colour information in even the hottest white areas - it looks like crap doing this on an 8 bit compressed jpg, but the fact is, there is tone there, and this is a MUCH narrower colour space than you will be working with in redcine.

I see some odd colour fringing artifacts, but there's no point in trying to judge this stuff from a jpg.

good luck,

ruari,

not sure how you can say there is no clipping as there definitely are some pixels hitting 255 in the red and the blue channel in the lower left part of the milk bottle, the collar, the bus bumper and the hat. yeah, it's only a few pixels in a highlight reflection but this is exactly where you'd expect them to be (and this was shot on a low contrast light situation).

could well be that this was due to post corrrections (you'll want some hot highlights for a picture to be good), it's justthat i'm weary to claim something about latitude from this image.

++ chris, who still doesn understand why someone would want to post a crappy jpeg with wrong color space if he wants to show what a great product he has.
 

tell you what, have a look at the gallery images at http://www.dalsa.com/dc/dcc/news/4k4real.asp

in particular http://www.dalsa.com/dc/documents/dead_in_street.zip

Now put that 4k rez 16 bit tiff file showing off the 4k dalsa camera through the same colour correction. Hows that for clipping in a low contrast situation on showcase images? Now compare and contrast the price.
 

I posted a screen grab from Photoshop with color channels histogram dispay. You can see pretty serious clipping in the highlights in the blue channel:

if this was a film camera, you would be using extremely HIGH contrast film, since this is very LOW contrast situation...
take it to new york on a sunny day and shoot people walking in and out of shadows of high rise buildings!
then i will believe it...
these studio and very limited outdoor "stagings" make me a bit worried...
ALL chip based cameras seem to get stuck on high contrast scenes... not just red... only film so far can handle that kind of 14 stop contrast
But i really would like to see someone do it!!

speaking of high contrast scenes... check out this show if you can

very cool
