			# Invertiere die Diagonale in der Registerkarte ''Tone Curve'' so, dass sie von links oben nach rechts unten geht.
			# Auch noch in ''Tone Curve'' gibt es die Wahl zwischen drei ''Base Tone Curves''. "Base Profile" und "Camera Raw Default" sind für gewöhnlich identisch und liefern mehr Kontrast, während "Linear" das Bild flacher wirken lässt. Zu empfehlen ist, ein DCP mit "Base Profile" und eins mit "Linear" abzuspeichern und in RawTherapee zu entscheiden, welche Variante dir besser geeignet scheint. Beide DCPs benötigen eine Überarbeitung mit RawTherapee, aber "Linear" benötigt eher mehr davon als "Base Curve". Wobei mit "Base Curve" die Farben auch schnell mal übersättigen könen. Also aufpassen.
			# Um das DCP zu erstellen, klicke auf "File > Export ''<your camera model>'' profile...". Zu empfehlen ist, wie im vorhergehenden Schritt angesprochen, zwei Versionen zu speichern.

			Um nun dieses DCP für Negative zu verwenden, öffne das Negativ im Editor von RawTherapee, gehe zu ''Registerkarte Farbe > Farbmanagement > Eingangsfarbprofil'', wähle ''DCP/ICP-Profil'' und suche dazu das neue DCP-File heraus. Selektiere noch ''DCP > Tonwertkurve''.

			Wenn du in RawTherapee Bilder unter Verwendung von DCPs bearbeitest, denke daran, dass bei der Verwendung von Tonwertkurven, die mit den RGB-Kanälen arbeiten (Tonwertkurve 1 und 2 im Werkzeug ''Belichtung''), nicht nur die Helligkeiten verändert werden, sondern auch die Farbsättigung. Steuere entweder die Farbsättigung unter Verwendung der Tonwertkurven-Modes "Gewichteter Standard" und "Sättigung und Überlagerung" oder du vermeidest das Problem ganz, wenn du im Lab-Farbraum arbeitest. Der Vorteil hierbei ist, dass die L-Kurve zur Korrektur der Helligkeit nicht die Farben ändert. Korrigiere also zuerst im Helligkeitsbereich mit der L-Kurve und danach die Farbsättigung mit z.B. der CC-Kurve.
	~~# In the Tone Curve tab invert the diagonal so that it goes from top-left to bottom-right (move the top point to the bottom).~~
	# Still in the Tone Curve tab, there are three "Base Tone Curves" for you to choose from. "Base Profile" and "Camera Raw Default" are usually identical and have more contrast, while "Linear" makes the image look flat. We recommend you save one DCP which uses "Base Profile" and another which uses "Linear", and see for yourself which one better suits your needs in RawTherapee~~. Both~~ DCPs ~~will require further image tweaking in RawTherapee~~, ~~but the "Linear" one will require more tweaking than the "Base Curve" one~~, ~~though the latter might over~~-~~saturate colors - keep an eye on that.~~
	~~# To create the DCP, click "File > Export~~ ''~~<your camera model>~~'' ~~profile...". As recommended in the previous step, save two versions.~~

	~~To use this new DCP for negatives~~, ~~once you have your negative raw opened in RawTherapee go to the Color tab > Color Management section > Input Profile~~, ~~and select Custom, then find this new DCP file~~. ~~Enable "Use DCP's tone curve".~~

	When tweaking images in RawTherapee using these DCPs, remember that using tone curves which operate on RGB channels (Tone Curve 1 and 2 in the Exposure tool) will change not only the lightness but also the color saturation the stronger your curves. You can control color saturation by using the "~~Weighted~~ Standard" ~~and~~ "~~Saturation and Value Blending~~" ~~modes~~, ~~or you can avoid the problem by working in~~ Lab* space. ~~The advantage of working in~~ L~~ab* space as the~~ L* curve does is that colors are not changed while you modify the lightness, so you can fix the lightness first using as strong an L* curve as you need, and then fix the color saturation using for example the CC ~~curve~~.

			Vielleicht arbeitest du bei deinen Aufnahmen noch immer mit ''analogem'' Filmmaterial. Oder du möchtest ältere Filme, die du eingescannt hast, bearbeiten. Meist handelt es sich dabei um sogenannte Negative. Bedeutet, helle Stellen im Bild werden dunkel wiedergegeben und dunkle Stellen hell. Bei Farbnegativfilmen kommt noch eine zusätzliche braun-orange Maskierung dazu und die Farben erscheinen auf den ersten Blick genau so negativ gemischt.

			RawTherapee besitzt keine unmittelbare Ein-Klick-Unterstützung für Negativmaterial. Aus diesem Grund beschreibt diese Seite etwas ausführlicher, wie solche Bilder trotzdem mit RawTherapee bearbeitet werden können.

Negatives are images with reversed lightness and colors, such as those produced by film cameras. RawTherapee does not yet have a flawless single-click solution for dealing with them, so this page serves to inform you of the possible workaround solutions:
# Invert a diagonal [[Exposure#Tone_Curves|tone curve]] either in the Exposure tool, or all of the curves in the [[RGB Curves]] tool. In the Color Management tool select "[[Color_Management#No_Profile|No profile]]" as the input profile. The downside is that there are tonal shifts when doing this.
# Use a negative Hald CLUT via the [[Film Simulation]] tool. The "RawTherapee Film Simulation Collection" contains one, get it from the [[Film Simulation]] page. The downside is that some controls might operate in reverse, such as the Exposure slider, and you may experience clipping in the shadows and/or highlights as these tools are not designed to work with negatives.
# In addition to using the neutral negative Hald CLUT as described above, if you have a successful workflow of not only inverting negatives but also toning them to your liking in RawTherapee or in other software, you could [[Film_Simulation#Make_Your_Own|make your own negative Hald CLUT]] which reproduces the whole look including negative inversion. To do that, apply the same steps to the "identity Hald CLUT image" shipped with the RawTherapee Film Simulation Collection as you would to a photo negative, save it under a new name, then open a photo negative in RawTherapee and apply that new Hald CLUT image. This lets you instantly achieve not only negative inversion but also your own toning with the click of a button, leaving you only needing to expand the histogram by adjusting the Exposure slider or using curves.
# Currently the best method is to use the DCP (DNG Camera Profile) for your camera model but edited in DNG Profile Editor so that the diagonal tone curve is inverted, then manually loading this DCP in RawTherapee for all negative shots. Method outlined below.

== Creating a DCP for Negatives ==

# Convert one of your camera's or scanner's raw photos (it can be the photo of the negative) to DNG by following the guide "[[How to convert raw formats to DNG]]".

# In the Color Tables tab, see whether the Base Profile called "Adobe Standard (''<your camera model>'')" is available. If it is, then select it. If it is not, then select "Choose external profile" and find the file titled "''<your camera model>'' Adobe Standard.dcp". The guide [[How to get LCP and DCP profiles]] explains how to get them and where to find them.

Both DCPs will require further image tweaking in RawTherapee, but the "Linear" one will require more tweaking than the "Base Curve" one, though the latter might over-saturate colors - keep an eye on that.
# To create the DCP, click "File > Export ''<your camera model>'' profile...". As recommended in the previous step, save two versions.

To use this new DCP for negatives, once you have your negative raw opened in RawTherapee go to the Color tab > Color Management section > Input Profile, and select Custom, then find this new DCP file. Enable "Use DCP's tone curve".

When tweaking images in RawTherapee using these DCPs, remember that using tone curves which operate on RGB channels (Tone Curve 1 and 2 in the Exposure tool) will change not only the lightness but also the color saturation the stronger your curves. You can control color saturation by using the "Weighted Standard" and "Saturation and Value Blending" modes, or you can avoid the problem by working in L*a*b* space. The advantage of working in L*a*b* space as the L* curve does is that colors are not changed while you modify the lightness, so you can fix the lightness first using as strong an L* curve as you need, and then fix the color saturation using for example the CC curve.
