And 1,000 other variables. Your "disagreement" just shows your lack of understanding of the situation. That of course is understandable and the reason I posted in the first place.
Advertising companies, movie studios, TV production houses, etc., all use state of the art color profiling equipment and spend countless hours and dollars trying to at least RECORD color correctly. Go into your local "Best Buy" or other TV store and stand in front of the wall full of TV's. EVERY ONE will render colors differently. Which one is correct JNB???
I have top of the line calibration equipment and can still only get a display device close. The greens may be perfect, but the reds will be out. Getting the red reigned in will push the blue out. And that my friend IS JUST THE DISPLAY and does nothing to correct the color errors introduced in the other stages of production!
Now how can a novice can take a snapshot on their digital camera, "fix it" in their $29 software package and post it on a forum and ensure that the REST OF US all see the same thing that the human eye sees when looking at their tank.
Take (3) 12xp rolls of 35mm negative film and (2) rolls of 35mm slide film expose each roll the same way (use a tripod and the same lighting and scene). Now drop those 5 rolls of film off at (5) different processors. You will get five DIFFERENT SETS of prints back. That is using the SAME camera and lens and FILM. Now do the experiment again and use (5) different brands and speeds of film. Your results will be even more varied. That is without the problems introduced by software on digital cameras, computers, video cards and monitors. That is without the problems introduced by display device sensors, phosphors, and all the other crap listed above.
I suggest looking into COLOR and how it relates to FILM and DIGITAL mediums. I tis a very interesting subject and an eye opener (no pun) if subjects like that interest you.
