1D vs 7D colors

After buying a Canon 1D, I've tried to compare how an 8 year old pro camera compares to a modern pro-sumer one... namely my 7D.

My first "challenge" was just a flower shot in the yard. The surprise was in the colors:

1D, Av mode, ISO 200, f/5.6, 1/160s
flower%201D.jpg


7D, Av mode, ISO 200, f/5.6, 1/160s
flower%207D%200.3ev.jpg


As you can see, the purples have a distinct hue difference (at least on my iMac hehe)

Btw, I had to add +1/3 stop exposure in Aperture to the 7D image to get the pictures to a visually similar brightness.. No other processing done. But since both cameras chose the same exposure time and the ISO + aperture were the same, it's a little perplexing.

Any ideas what is causing the difference in hues? I tried to tune the white balance as well but it seems to persist.. Btw, the 1D one is more faithful to the actual flower (confirmed by my wife).

Edit: Oops forgot to mention.. EF 70-200/2.8L IS II lens, handheld, from same position (marked on the ground), and zoomed in appropriately to compensate for APS-C vs APS-H and frame subject in a similar way.
 
Did you shoot in RAW format? If the answer is no, the camera's software will be responsible for processing the colours, amongst other things.
 
Yes, they were both shot in RAW. Of course Aperture probably has different default profiles for different bodies, so it might be the culprit..
 
I've found the same thing shooting with a 7D side by side with a 1DsII. The 7D had more saturation as standard from the files.
 
He explained in his OP.
 
Yep, if they're JPEGs, the Canon Standard Picture Style will add a bit of punch and saturation compared to the 1D.

Try setting the 7D on 'Faithful' or 'Neutral' and I reckon they'll be a lot closer.

edit: post already superseded by the time I made it.
 
Thanks for the comments, I should've mentioned they were shot in RAW in the original post.. as such I don't think any camera settings should affect the RAW file except the exposure parameters?

Could it be the CCD sensor being sensitive to colors differently from the CMOS?

Different sensors / hardware / software, the only way Canon could get it exactly the same would be to do a full spectral calibration on each camera.

I used to design RF power meters, they worked by measuring the effect of the RF power on a diode. Even though all the diodes were identical they all required calibration & a 5th order polynomial to map them to the meters response. ie there is no such thing as identical :thumbs:
 
Why not use Canon Picture Style Editor to set your own custom style and upload to the camera, then every shot will be how you want it with no need to faff around in LR or Aperture
 
Thanks again for the comments and suggestions, I'm not looking to make both cameras equal, just intrigued by the differences and trying to understand the reasons. It might not make me a better snapper but it satisfies my inner übernerd..

I'll probably try to do more comparison shots in the weekend, will post if anything striking pops up. But I'm liking the sweet & mellow 1D colors a lot..

Oh and I don't think Picture Styles has any effect on RAW images. At least I've never even touched that setting since I started shooting RAW.
 
Different cameras render different scenes differently. :)

I've seen a fair bit of discussion (I think on this forum amongst other places, but I can't find the thread) about the differences between the 5D and the 5DII, particularly with handling of reds. Some people prefer the 'look' of one over the other.

It's not unthinkable that you might find some variation between two copies of the same camera model, although they should be minimal if the manufacturers are doing their job properly.

It doesn't if you're using Aperture for your RAW processing.

If you were to do your RAW conversions with Canon DPP, though, then the Style set in camera is honoured by the software, using the same algorithms that the camera does to generate a JPEG. Of course, you can still change the picture style to something else in DPP if you like.

Lightroom allows you to select Adobe's emulations of Canon's Picture Styles in the Calibration setup, but it doesn't pick them up automatically from the EXIF data.
 
Bit like tryin a Ferrari 355 against a 430 different era's and what really is the point?

This is imo quite interesting:geek:. Perhaps you should photograph a kodak colour chart under a constant light source. i dont think focal length used plays a great role in the colour repro of a camera. but i suspect the low pass filter does and i am sure they are different in the 2 cam's.

If you are really keen you'll have to standardize the 2 camera as much as possible i.e custom WB for the lighting, colour profile will have to be the same in the 2 cam's.

let us know how u get on...
