A Simple Workflow for RAW Processing
- By: Luis Argerich
In a previous article I discussed 7 reasons to shoot RAW. If you are looking for the most flexibility and the best image quality you can squeeze from your camera, RAW is the way to go. In this post I’m going to discuss a simple workflow for RAW that will produce a nice final result. You can adapt this workflow to suit your own style.
The Basic Recipe
Camera => RAW => 16 bits TIFF => JPG
The RAW file is processed by your favorite RAW developer, producing as the result a 16 bit TIFF file, that is the master-file that will be processed/edited and saved with the final result. From the master TIFF file you can then extract JPGs for the web or for printing resizing and sharpening as needed.
Choosing a RAW Developer
There are a lot of good options for good software out there to process RAW files. As a basic start, if you are new to RAW shooting, RAW Therapee is free and quite capable. I shoot Canon and my favourite RAW developer is DXO optics. DPP free from Canon is also good. I evaluate RAW developers only by image quality, I don’t really care about features as they are all very similar I just want the best result possible. Everyone has their own preference.
What to do with the RAW file
When you process the RAW file the following are recommended:
- Choose the White Balance
- Adjust Exposure (a must if you expose to the right to avoid noise)
- Apply noise reduction
- Correct Lens defects such as chromatic aberration, distortion and softness
- Adjust saturation
- Fix dust spots (optional)
The following processes are NOT recommended:
- Sharpness and unsharp mask
You must avoid the temptation to apply sharpness besides correcting the lens softness. Sometimes the result of a RAW developer looks better than a 2nd program but only because the first piece of software is applying some aggressive sharpening. That’s cheating. Sharpening is always the final step before publishing or printing your file as it depends on the size of your file.
The most important adjustments are exposure, white balance and saturation. By definition most RAW files are uncontrasted and unsaturated so unless in special cases there’s always a need to boost the saturation.
After applying these adjustments save the result as a 16 bit TIFF file using Adobe RGB as the color space. This is to make sure you don’t lose information and you have all the room you need to edit the file as needed.
Editing the Master TIFF file
Once you develop your RAW file you get a 16 bit TIFF. From here you can do whatever you want with your photo, that’s part of your processing.
What to edit in the TIFF file
- 2nd noise reduction (if needed)
- contrast & curves
- fix dust spots
- cloning & patching
- cropping to taste
- selective editing, layers, etc
- dodge & burning
In short: Do whatever you need to do with your photo except resizing and sharpening.
What NOT to edit in the TIFF file
The final step: creating a JPG output
From your saved edited master TIFF file you will create the JPGs you need to publish and/or print your photo. The process is simple:
- Convert the color space to sRGB
- Resize (use a good interpolator)
- Apply sharpening to taste
- Save as JPG
There are a zillion variations to this workflow, I tried to keep it simple and flexible. The editing process with the master Tiff file can involve layers, plugins, tools and many different things depending on how you process your files. Once again, this is my process and you can take what you want from this article.
I hope this will help you get started with RAW, it can be very simple or very complex depending on your needs but it will produce better results than shooting JPGs from the camera. At least until the camera software gets smarter than us!
