Custom Profile to Preset Resize Parameters

Software RawTherapee
#1

I am trying to create a custom profile which will preset some of the Resize parameters in RT 5.9. Specifically, I would like to preset:

  • Resize on
  • Applies to cropped area
  • Specify bounding box of 3840 x 2160

I made the following profile but it is setting

  • Resize on
  • Applies to cropped area
  • Specify height of 3244 x 2160
[Version]
AppVersion=5.9
Version=349

[Vibrance]
Enabled=true
Pastels=30
Saturated=30
PSThreshold=0;75;
ProtectSkins=false
AvoidColorShift=true
PastSatTog=true
SkinTonesCurve=0;

[Resize]
Enabled=true
AppliesTo=Cropped area
Method=Lanczos
DataSpecified=3
Width=3840
Height=2160
AllowUpscaling=false

What should I change?

What are the dimensions of the uncropped image? Is the ratio of dimensions near 1.5?

I shoot Nikon so my images are 3:2. Why?

I want to apply this profile when I am going to crop the image 16:9 and export it for display on a 3840x2160 monitor

I’ve never used custom profiles in RT, so I was guessing that maybe the aspect ratio (3:2) was being retained and the size was being reduced to fit within the dimensions of the box you defined. With your confirmation of aspect ratio, it seems that this is what happened.

i wonder, if you also activated “crop” for this. Since the original format is 3:2 but you are going to 16:9, you will need both: crop and resize.

given, the original format was 6032 to 3393 try this:

[Crop]
Enabled=true
X=0
Y=315
W=6032
H=3393
FixedRatio=true
Ratio=16:9
Orientation=As Image
Guide=Rule of thirds

Turning on both crop and resize did the trick. Thank you, @marter
