Bigger IS Better

I don't see the point of other people posting "sharp eyes" photos. One major problem with the comparison set is we don't know if the original images were accurately shot to the same scale - relationship of the subject size to each format. Thus we don't know if the images that are cropped to the eye really compares anything.

You all have to wait to see the pictures

when there is a sensor for this camera :D:D:D

if you want to see skin detail

Im not at all sure it needs to be bigger, from Sigma's SD14 foveon dSLR

If you are going to bother with a comparison make sure the exposure and color balance is properly adjusted. You put up an M8 photo that is underexposed, flat and color shifted a nasty green compared to a balanced, properly exposed 5D image and then say can't you believe your own eyes? Here is a one 1:1 crop of the original jpegs with the M8 adjusted so it has a full contrast range and a similar color balance to the 5D. I also posted a reduced file so you can compare the flesh tones and modeling. This should have been done in raw conversion and if done properly the M8 file would look better then just adjusting an improperly processed jpeg.

If you compare 100% crops they cannot be the same size at a given resolution if the files are not the same size either. Is this what you mean when you say that the original M8 jpeg is adjusted or are your M8 and 5D files the same size actually? Just curious.

The eye on the 5D file is bigger because it is 12MP not 10MP. The 1:1 crops are just that - showing the full pixel detail. No adjustment for size has been made.

 

The adjustment to the M8 file was to color balance it more neutral (like the 5D) and increase the contrast as the histogram of the M8 file showed underexposure and an improperly set raw conversion. The way the files where originally presented sdai might as well have taken a piss on the M8 file and posted it and said -O look the M8 looks worse! You would want to compare two neutral color balanced, properly exposed full range files if you expect to make any useful comparison. As these were taken in a studio with strobes there is no excuse for the state of the M8 file. The color balance could have been set and the histogram checked during image capture.

I'd add one more thing. You really have to know the respective cameras to be able to compare them. I would not use the same lighting to get the same result with an M8 and a Canon 1 series camera. I'd use a reflector that had more specularity for the Canon and a little softer light for the M8.

 

The Canon tends to fill the tiny highlights on the texture of the skin smoothing it out. This can be a good thing or it can make the skin look like plastic or like its been smoothed with retouching. With the M8, maybe because of it's lack of AA filter you must be careful of these tiny borderline specular highlights. A bit more matte powder and a less specular light might be needed -depending on the look you want. You can also fill these tiny highlights on the texture of the skin in post.

Perhaps next time when I post something like this, I should label it as "for entertainment only". :D

 

But seriously, if I post some lab test numbers it would be a crushing blow to your mind ... if my memory serves correctly, the M8 resolves about 1300 line pairs per picture height, the 1Ds Mark II can do about 1600 lp/ph ... the H3D-31? man, you'd wish I were wrong, that number is about 2300 lp/ph. LOL

I've said (I think) 3 times in this thread already ... these pictures were not shot for comparison purposes, it was me who put them together.

 

But, let's put it this way, if you take two identical shots using two different cameras ... at the same view angle both pictures will cover the same stuff, same information, right? the same image projected on a larger sensor will no doubt have more line pairs resolution than on the smaller one. Easy math.
