In this article we're going to use the initial Retinex concept (based upon Ipol exploration). It had been designed during the seventies and was at first made for this kind of application and never for your way it's been subsequently Utilized in Rawtherapee and somewhere else. We are going to:

Open the raw Photograph. RawTherapee routinely makes it appear like your camera's output. In case you are happy with The end result, you happen to be completed. Else Continue reading.

Both of these features consider the ΔE of the graphic in order to avoid modifying the selection place protected because of the RT-place:

Established the "Scope (color applications)" slider to fifty (this worth will probably be employed by the Shadows/Highlights Resource when it truly is additional and we will utilize the individual Scope sliders for each of your Log Encoding and Exposure tools).

If you need to do use Publicity, then it is suggested (although not necessary) to alter the parameters of "Form detection" in Configurations as follows:

Be aware that the option "Normalize luminance" is checked. This makes sure that the average and variance with the luminance values are the same as in the initial impression.

You can see the impression now features a dominant shade. This is due to utilizing the Blend operate Using the LC(H) curve.

Change the "Laplacian threshold deltaE" slider (which requires into consideration the deltaE with the graphic to act with a next Laplacian operator). This processing is upstream of your Scope algorithms and will take note of differences inside the track record.

A wavelet-degree selector with threshold which allows you to pick out An array of levels as opposed to just deciding on a most number of ranges. The algorithm routinely lessens the number of levels if the selected space (in pixels) is inadequate: for amount nine a minimum of 1024 pixels is required.

Alter the white equilibrium (Color tab). With no understanding of the one that took this picture we do not know everything concerning the lights disorders. Are they LED or incandescent lamps? How was the foreground lit? In cases like this:

It should be mentioned that there are correctly only two choices for Dehaze & Retinex, Simple and Superior (the Basic and Conventional selections are similar). Modifying the GUI to reflect this is apparently hard at this stage. Hue, chroma, luminance references plus the principle of your algorithm

The purpose of this tutorial is not to display the 'ideal' method of processing this graphic, but to indicate that by integrating a pre-processing module upstream of Ciecam, you'll be able to course of action illustrations or photos with an incredibly large dynamic variety so which they can then be very easily processed by Ciecam (Cam16).

A Centre C consisting of the adjustable circle whose size (diameter) and placement is often diversified utilizing the mouse or cursors.

This mask are going to be used to differentiate the denoise amongst the history and the rest of get more info the impression i.e. the harvest mouse plus the vegetation.
