the norm is the basic value without artificialization like the eye exposure which you just mentioned. if i put in the sky and the sun into corona, it looks overbright and needs to be adjusted which means its bad.

i dont own a camera nor do i care about cameras. rendering shouldnt be focused on cameras but on a universal standart, a "norm".

yes i do refuse a hdri because im not going for archviz nor still images. with hdri's you cant change the time of the day and it blocks one off. And yes it would be highly possible and easier to just have one basic "exposure" (one button solution) which would be the standart, like i wrote it is in some other render engines and game engines. otherwise its not physically accurate and is just playing around with the settings trying to use special tricks to make something look how it should be but thats not what a renderer should do. dont corona aims for realism? if yes then why it uses camera settings when the real world has no exposure but a constant physical lightning approach. exposure will never be physically correct because its not real and thus you cant have like you said "a one button solution" but with a "standart" you would have it.

thanks for the answer but no. dont you see that it looks just plain unrealistic? i thought corona is made for realism but its all fake. i want to make grass that looks golden when the sun is low and shines on it, bright green when the sun shines through at midday and "muddy" when its not in the sun, like in real life. but all i see is one angel one daytime solutions which is weak. And the sky is already at 0.2 and it was so dark that i had to add a brighter color to it just to make it look not dark grey-blueish but white-blueish. Its all a mess, it seems that corona isnt good in a sense of good for anything else beside still images and archviz. i couldnt imagine an animation with corona where the time of day changes, there is no universal solution. even games have universal solutions, there is no need to adjust the exposure (btw its the most stupid thing ive ever heard, in the real world is also no exposure so why in diverse render engines? makes no sense at all) and the grass fits to the time of the day because its made physically right. i guess i just switch to mental ray, i hope its better implemented.

I didnt saw any tutorial on how to make really realistic grass, all i found didnt satisfied me. Ive been trying to working since around 4 days on a decent grass material but cannot do it and when im almost there then everything else (contrasts, colors and exposure) are unbalanced which applies especially to the skies because for normal dark shadows i need to but the sky on a level of like 0.2 but the sun on full 1.0 which gives very strange results (i will never use a HDRi, so keep that in mind). So to the point, the grass never seems real enough, especially when i try the tutorials. (btw this are more or less the foliage tutorial settings with slightly changed colors, the material just dont work)

for the attachments, here are some pictures on how i would like the grass and sky to look (note that the grass differs from sun and viewing angle and strenght very much which i would also like to "simulate") plus my hopeless try to create grass with the provided foliage settings..
