Are ISF Day & Night base profiles the same?

3217 Views 8 Replies 5 Participants Last post by  turbe
Meaning to say, if all the settings on both ISF Day and Night are zeroed out would the underlying profile be identical (on a 9G Elite)? I ask because I'd like to try and experiment with two differnet ISF Day calibrations that I've done for a given input, and it would seem the easiest way to do this would be to leave one in ISF Day and put the other in Night. But this would only work if the base profiles are the same between the two.

We have to ask D-Nice for sure, but I think so.
Yes, with the same numbers they act the same.
Yes, Chad posted the answer

There is absolutely NO SENSE in spending a whole lot of time trying to find an "ideal" "Day" mode - everytime the light changes, your image will change. 10am will look different than noon or 2pm or 5pm. Clouds will make the images look different than a clear day. The paint on the walls, carpet/floor color, and ceiling color will all change what you see and those change also depending on the temp of the light entering the room. Get something you like, make it bright enough to see, and forget about it. In general, using your dark room calibration and simply making it brighter works as well or better than any other Day mode you will be able to come up with. Frankly, if you could adjust Optimum mode a bit (you can't), that would be an ideal Day mode because the panel would adjust up and down depending on the amount (and color would adjust also in Elites with the extra sensor installed) - but the factory Optimum settings are just a bit over the top - not too much, but it would be nice if you could tweak the grayscale and decrease color saturation a little.

That's what isf Auto is used for, adjust per sensor from your base calibrated/adjusted settings.



Anyways, back to the question, the ISFccc Memory labels isf Night and isf Day are meaningless label names.. they could be A and B, His and Hers.. too bad we can't change the name(s)....

That's not what I'm trying to do. In my case I have two Chroma5s, and they each read just a bit differently, even though both were calibrated by X-Rite on the same day. What I'm planning to do is use ISF Day for one, Night for the other. I'm hoping that at that point using grayscale ramps, test scenes, anything, will help me tell if one is inducing anything on the display that the other is not. I don't have a multi-thousand dollar control meter for quantitative comparison.

Can you use ISF AUTO as if it were a normal ISF day or Night mode if you don't have the external sensor connected.



AKA: if I copy the settings over from my night or day would it look just like the mode I copied?
It uses the sensor regardless...
