Right here we're going to use the first Retinex idea (dependant on Ipol study). It absolutely was made from the seventies and was initially made for this sort of software rather than for the way it has been subsequently Employed in Rawtherapee and somewhere else. We are going to:
To overcome this problem keep away from combining a number of mask settings, regardless of whether or not they use Blend or not.
Use "Stay clear of shade change", which by default will Management the gamut and implement Munsell correction, then use an Excluding location on the spots with reconstructed highlights that you simply desire to protect.
Produce an Rt-location that extends the TBLR factors outside of the boundaries in the picture both by using the Full-impression selection, or by utilizing a Normal location and lengthening the points manually.
The issue launched by logarithmic conversion to compress the data (Log two) is that it's not linear.
Gamma & Slope: Gamma and Slope are according to the exact same basic principle as sRGB gamma. The purpose functions on the Luminance L* channel using a linear part for your darkish spots and also a parabolic curve thereafter. The curve is continual without any discontinuties.
In a very tricky image it will more info most likely be required to activate all 5 ways to attempt to uncover the right harmony. The end result is often a make a difference of specific taste and is fairly subjective.
Be certain that the mask is enabled in "Mask and modifications" and which the "Permit mask" box is checked.
Set "Restoration threshold". The closer the slider should be to "2", the greater the dark and really brilliant parts of the mask might be taken into account and restored to the first image values.
Once the user has utilized a black and white module or perhaps a black and white film simulation ahead of implementing any regional adjustments, this Check out box will be certain that colour won't reappear when local adjustment configurations are utilized. Recursive references
Calculates the ΔE (perceived distinction between two colors considering hue, chroma and luminance) between the central zone and the current pixel.
Contrast threshold: lets you choose the portions of the graphic which will be influenced dependant on the texture.
Initially, a little background. A raw Photograph has a dump of sensor info, that makes up the bulk of your Uncooked file. This sensor facts won't appear to be a fairly graphic, in fact it doesn't seem like something - it is actually "raw" facts, ergo the identify. It should be "cooked" to seem like the picture you noticed from the viewfinder. Your digital camera cooks the raw info into a fairly picture, which it merchants for a JPEG file Within the raw file (Indeed, even when you are capturing in only "RAW" mode as opposed to "Uncooked+JPEG" method).
You may additionally ought to load the appropriate calibration curves into your graphics card for those who constructed your keep track of color profile in addition to them, though the way you do which is outdoors the scope of RawTherapee.
