  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

Red & Dslr...

Hey Jim, to do special characters such as: ü

hold down alt and on the NUMBERPAD punch in a 4 digit number.


You can look it up in word by inserting a symbol, scroll down untill you see the character you want, highlight it, and make sure in the lower right corner, it's not hex, but ASCII. It'll then give you a code like 253 or something - just put a 0 in front.

ü = 0252

Cheers
 
blue channel noise differences

blue channel noise differences

The blue channel noise certainly looks different, also the sharpening artifacts, compare the 1:1 crops of the same area on the color chart. I'm suspecting the Canon may have more blue noise, especially since Jim made a point of mentioning noise. The colors are slightly different, more obvious in the blue-only chart than to my eye. I guess "A" is Canon and "B" is Red based only on blue channel noise. But certainly, both of them are good quality images.

B looks like wavelet compression to me.....I can see it in the blue channel image on left is A right is B
 
... guess in the end Jim's point is that making people scratching their heads so long to tell a RED frame from a DSLR frame is already an achievement.
If this is the case i can say that the trick is made easier by our b16 inexperience ... wonder what Shawn could say about this little game :biggrin:
 
this is REALLY simple

this is REALLY simple

just forget about all things connected with resolution, color etc.

if you have TWO different cameras with one sensor size SMALLER and second one BIGGER - and you use same framing (almost) and same f stop (5.6) (iso is also same - as stated before - 320 asa, but this is not important here.)
the question is - where you will see shallower DOF? on smaller or bigger sensor size?

the answer is really simple... just look closer at DOF on color tubes...(if the word "tube" is correct in english)

i am betting 100$ that the picture with the shallower DOF is NOT RED.

who wants to bet?

Are those white lines around the boxes sharpening artifacts or CA? Image A may have more blue noise but it's a nice noise. Image B looks like it's been denoised which on the one hand makes me think it's the Red since I've seen Red grabs with that "median filter" look. But on the other hand, if the Canon image has been scaled up slightly it might have that blurry, loss of detail look.
 
I would be happy with build 15 image quality not sure what the big deal is. It's a compressed camera that looks fantastic. Lets move on and get the bugs and post worked out.
 
My initial guess was that the bottom image was RED and the top the Canon. I have no idea whether that's correct, but my preference for overall image appeal (which is influenced by the different gamma in the two images) is definitely the top. If the top is RED, I am overjoyed.
 
It's all about B16.

RED with B16 makes even better still picture than Canon 1D MKIII.

That is exactly what Jim wanted to show us.

Top RED.

Bottom Canon.

Take it or leave it.
 
Looking at the blacks in the handle portion of both i see more artifacting that
I attribute to the smaller bandwidth of the Red image in Frame A

But again we must remind ourselves, these frames are wizzing by at 24 per second, cleaner than anyone will possibly see, and I doubt any would be able to tell the difference even if you did a side by side, motion flip book style
test.

Congratulations Guys my jaw droppith in your honor
 
The images look so similar to me that I'll try to use logic instead to figure this one out...

If you were to do a test such as this. I'd imagine that you'd take the shot first with the RED and then try to match framing/settings with the second camera afterwards. The second image is a little bit wider... Jim had to crop and scale the DSLR pic to match the RED one, but he cannot crop and scale to much to fit the original first image, otherwise we'll be affecting the resolution too greatly. So you get it close enough and call it a day...

Secondly, the top image is in better focus...which camera does Jim shoot with more often? I think Jim is more likely to nail focus on a RED shot than a DSLR shot.

I say Top image :)
 
there is no clear answer...period
when pixelpeepers got problems to tell the difference using photoshop, 200 %crops,bluechannel analysis, histograms etc...

i can cleary say that no one ever will be able to tell the difference in a
suspense scene, where the tension almost breaks your neck...

i am talking for myself, but hey who cares which one is red or canon?
i am really happy today...

This is very true, If its this hard to tell the difference on a still wait till
you see it in action
 
My guess is that the top is RED and the bottom is Canon. I did some color checking in PS and the top pic seems to lean more to the blue side.

My conclusion is based on the fact that RED is daylight balanced therefore it must be the top pic.

Hell, i just sold myself on it ...... anyone else?
 
Hate to be a spoil sport but if you really want to go head to head with an SLR you really need to shoot a wide shot exterior at dusk.

I have just travelled for a month shooting paris and venice on BOTH red - a nikon d3 and a canon 1DmkII.

On build 15 the red does not come close to the dslrs. Sorry.

I am very hopeful that build 16 has huge advances in lowlight but in saying that - I still am deliriously happy with my red.

Personally I think is an unfair comparison considering red has to shoot 25 frames per second and a top end slr does a max of 1 a second without buffering.

Just trying to be honest and not a fanboy.....
