RAW photography on a Samsung Galaxy Ultra is most useful when you expect to edit the photograph afterward. Samsung’s Expert RAW app captures images as 16-bit Linear DNG files alongside JPEG versions and gives you direct control over settings such as ISO, shutter speed, white balance, exposure and focus. That extra information and control can give you considerably more latitude when correcting exposure, recovering highlights, shaping shadows or changing color—but it also produces a less finished file that generally needs editing.
The key is knowing when that flexibility is worth the extra storage and editing work. RAW makes the most sense for landscapes, difficult lighting, night scenes, architecture, deliberate long exposures and photographs you intend to print or substantially edit. It is usually unnecessary for quick snapshots, social-media posts, rapidly moving subjects or images you want to share immediately. On the Galaxy S26 Ultra, Expert RAW is supported, but the exact features available can vary by device and software version.
What RAW Actually Changes
A normal smartphone photograph is already heavily processed before you see it.
The phone may combine multiple exposures, reduce noise, sharpen details, adjust white balance, map highlights and shadows, increase local contrast and apply color processing. The result is convenient: you press the shutter and receive an image that is generally ready to view and share.
RAW takes a different approach.
Instead of relying entirely on the phone’s finished rendering, Expert RAW saves a Linear DNG 16-bit RAW file that retains substantially more image information for subsequent editing. Samsung says Expert RAW saves both JPEG and RAW files, allowing you to use the JPEG immediately while retaining the DNG for more extensive editing.
That does not mean RAW is an untouched copy of exactly what a conventional camera sensor sees. Smartphone cameras still involve computational imaging, and Expert RAW itself is part of Samsung’s camera pipeline.
The important distinction is that the DNG gives you considerably more control over the final rendering.
RAW vs JPEG: The Practical Difference
| Characteristic | Galaxy JPEG/HEIF-style finished image | Expert RAW DNG |
|---|---|---|
| Ready to share | Yes | Usually needs editing |
| File size | Generally smaller | Generally larger |
| Exposure adjustment after capture | More limited | More flexible |
| White-balance adjustment | Possible, but constrained by the rendered file | Much greater flexibility |
| Highlight/shadow recovery | Limited by the processed image | Greater editing latitude |
| Color grading | Possible | Better suited to substantial adjustments |
| Storage requirements | Lower | Higher |
| Editing workflow | Optional | Usually worthwhile |
| Best suited to | Everyday photography | Deliberate, editable photographs |
The exact result depends on the scene, camera, exposure and software used to process the DNG. RAW is not a guarantee that an image will contain more recoverable information in every situation.
When RAW Is Worth Using
1. High-contrast landscapes
Landscapes are one of the clearest cases for RAW.
Imagine a bright sky above a darker foreground. The phone’s normal processing may produce a pleasing result immediately, but you may want a different balance between the two.
RAW gives you more room to make that decision yourself during editing.
For example, you might:
- Lower highlights in the sky.
- Open shadows in the foreground.
- Adjust the overall white balance.
- Reduce excessive saturation.
- Apply local contrast selectively.
- Create a warmer or cooler interpretation.
Samsung specifically promotes Expert RAW for situations where photographers want greater control over highlights, shadows and color during post-processing.
The important qualification is that RAW cannot recover information that was never captured. If the brightest part of the sky is completely clipped, editing cannot recreate its missing detail.
2. Sunrise and sunset
Sunrise and sunset scenes frequently contain extreme brightness differences.
The sky may be bright while buildings, trees or people in the foreground are much darker.
This is exactly the type of situation where having additional editing latitude can be valuable.
RAW is particularly useful if you want to make the photograph match what you remember seeing rather than accepting the phone’s automatic interpretation.
3. Difficult artificial lighting
Mixed lighting can produce difficult color casts.
A photograph may contain:
- Warm indoor lamps
- Cool daylight
- Colored LEDs
- Street lighting
- Reflections from nearby surfaces
The phone has to decide what the scene’s white balance should be.
With a JPEG, you can still make substantial color corrections, but you are working with an already rendered image.
Expert RAW gives you much more control over white balance and other image characteristics. Samsung specifically identifies white balance as one of the controls available in Expert RAW.
This can make RAW particularly useful for interiors, architecture and evening street photography.
4. Night Photography
Night scenes are another good candidate—but with an important caveat.
RAW gives you more control over the final image, but it does not eliminate the fundamental difficulties of smartphone night photography.
Low light means:
- Less available light
- Higher potential noise
- Greater risk of motion blur
- More challenging autofocus
- Greater exposure differences between artificial lights and dark areas
Expert RAW can be useful when you want to control the resulting image yourself, particularly for static scenes.
Samsung also provides specialized astrophotography functionality in Expert RAW on supported Galaxy devices. The current Samsung documentation describes controls for focus, white balance and exposure time, along with a Sky Guide for supported astrophotography features.
That is a different use case from simply switching on RAW for a normal nighttime snapshot.
5. Astrophotography
If you are deliberately photographing the night sky, Expert RAW can become substantially more useful.
Samsung’s astrophotography mode allows supported Galaxy devices to adjust the shooting duration and use a sky guide to identify celestial objects.
For serious night-sky photography, stability becomes critical. A tripod or similarly stable support is far more important than simply selecting a RAW format.
RAW can then give you more freedom to control:
- Overall exposure
- White balance
- Contrast
- Shadow brightness
- Color
- Noise reduction during editing
There is also an important distinction between capturing more data and capturing better data. A poorly exposed, shaky RAW photograph is still a poor photograph.
6. Architecture and Interiors
Architecture is another strong RAW use case because interiors often combine dark areas with bright windows and artificial lighting.
Suppose you photograph a room containing a large window.
The phone may have to balance:
Dark interior + bright exterior + mixed artificial lighting.
RAW gives you greater freedom to decide how that balance should look later.
It also makes deliberate color correction easier when walls, flooring and furniture need to appear neutral.
7. Photographs You Intend to Print
If you are taking a photograph specifically for a large print, preserving editing latitude becomes more valuable.
You may want to:
- Adjust color precisely.
- Reduce distracting highlights.
- Recover darker areas.
- Apply selective sharpening.
- Produce a specific crop.
- Match the photograph to a printer or paper.
That does not mean every printable photograph must be RAW.
A well-exposed JPEG from the Galaxy Ultra can still produce an excellent print.
RAW becomes more useful when you care about controlling the final interpretation of the image rather than simply obtaining a technically good snapshot.
When You Probably Shouldn’t Use RAW
RAW is not a universal upgrade.
Everyday snapshots
If you’re photographing lunch, a receipt, your friends or a quick family moment, the standard Camera app is usually more convenient.
You probably do not need to spend time editing a DNG afterward.
Social-media photography
If your workflow is:
Take photo → post photo
RAW adds an unnecessary step.
The standard camera’s processed output is designed precisely for this kind of use.
Fast-moving subjects
RAW can be particularly inconvenient when photographing unpredictable movement.
If the subject is moving quickly, capturing the moment is more important than maximizing editing latitude.
Children, pets and sports are good examples.
The phone’s computational processing in the normal camera can be more useful than having a DNG that you never have time to edit.
Large batches of photographs
RAW becomes less attractive when you are taking hundreds of images.
Samsung notes that shooting more than 10 photographs continuously in Expert RAW can result in longer intervals because of high-resolution image processing.
That matters when you are photographing an event or trying to capture a rapidly changing scene.
RAW Does Not Mean “More Megapixels”
This is one of the most important distinctions.
RAW and resolution are different concepts.
RAW describes how image data is stored and how much control you retain during processing.
Resolution describes the number of pixels.
A higher-resolution JPEG can contain more pixels than a lower-resolution RAW file, while the RAW file may still provide substantially more flexibility during editing.
The Galaxy Ultra’s multiple cameras add another layer to this.
Choosing Expert RAW does not mean that every photograph is automatically captured with the main 200MP sensor. The camera and mode determine which hardware and resolution are being used.
The practical question is therefore:
Which camera and resolution are appropriate for the scene, and do I need RAW editing latitude?
Use the Main Camera for the Most Demanding RAW Work
When image quality and editing flexibility are the priority, the main camera is generally the most useful starting point.
The Ultra’s primary camera has the largest and most capable imaging hardware in the system, while the telephoto cameras are optimized for their specific focal lengths.
That means RAW does not eliminate the importance of lens choice.
A RAW file from the wrong camera for the scene is still the wrong photograph.
If you are photographing a distant subject, the telephoto perspective may be more valuable than moving closer and cropping the main camera.
If you are photographing a landscape, the main camera may provide a more useful balance of detail and light-gathering capability.
Learn the Manual Controls
Expert RAW becomes much more valuable when you understand what its controls are doing.
Samsung identifies several direct controls, including:
- ISO
- Shutter speed
- White balance
- Exposure
- Focus
You do not need to use all of them manually.
In fact, changing everything at once can make photography harder.
Start with one control.
ISO
ISO affects the camera’s sensitivity/exposure behavior and has an important relationship with image noise.
As a general principle, avoid increasing ISO unnecessarily.
If the phone is securely supported and the subject is stationary, a longer shutter can sometimes allow a lower ISO.
Shutter speed
Shutter speed determines how long the camera gathers light and strongly affects motion.
A slower shutter can brighten a dark scene but increases the risk of blur from subject movement or camera movement.
White balance
White balance controls the color temperature of the photograph.
You might deliberately make an evening photograph warmer or correct an unwanted yellow cast from artificial lighting.
Focus
Manual focus can be useful for controlled scenes, particularly when autofocus is repeatedly selecting the wrong subject.
It is less useful when the subject is moving unpredictably.
RAW Gives You Control—Not Immunity From Bad Exposure
One of the biggest misconceptions about RAW is that almost anything can be fixed afterward.
It cannot.
RAW gives you more latitude, but there are limits.
If you severely overexpose a bright sign, sunlight reflection or the sky, the brightest areas can lose information.
Likewise, extremely dark areas can contain so much noise that opening them aggressively produces an unattractive result.
The best workflow is still:
Expose carefully → capture stable image → edit deliberately.
RAW is the safety margin, not a replacement for good exposure.
RAW Files Need an Editing Workflow
Before using Expert RAW regularly, decide where the DNG files will go.
A typical workflow might look like:
Galaxy Ultra → Expert RAW → DNG → Lightroom or another RAW editor → export JPEG/HEIF
Samsung specifically promotes Expert RAW’s compatibility with editing workflows such as Adobe Lightroom and provides a Samsung Expert RAW profile for post-processing.
The exact software you use matters less than understanding the workflow.
You need somewhere to:
- Store the original DNG.
- Edit the photograph.
- Export a finished version.
- Back up the original if the photograph matters.
If you do not intend to perform those steps, RAW may not provide much practical benefit.
Don’t Delete the JPEG
One of Expert RAW’s useful characteristics is that Samsung saves both the JPEG and RAW file when shooting.
That gives you a convenient fallback.
The JPEG may already look exactly how you want it.
The DNG remains available if you later decide that you want to change the exposure, color or tonal balance.
This is one reason Expert RAW can be more practical than treating every photograph as an either-or choice between “automatic” and “professional.”
RAW vs Samsung’s Normal Camera Processing
The choice is really between two philosophies.
Normal Camera
The phone asks:
“What finished photograph should this scene look like?”
It then applies computational processing to produce an immediately usable image.
Expert RAW
The workflow asks:
“How much information and control can I retain so I can decide what the finished photograph should look like?”
Neither approach is inherently superior.
The normal camera is optimized for convenience and computational processing.
RAW is optimized for control and post-processing.
A Useful RAW Workflow for Galaxy Ultra Owners
If you are new to RAW, avoid changing everything at once.
Try this:
1. Choose a static subject.
A landscape, building or still-life scene is easier to learn with than a moving person.
2. Open Expert RAW.
Samsung makes the app available through the Galaxy Store on supported devices.
3. Start with automatic exposure.
Learn what the RAW file gives you before introducing manual exposure.
4. Capture the same scene in normal Photo mode and Expert RAW.
This is more educational than comparing RAW to a theoretical specification.
5. Edit the DNG.
Adjust exposure, highlights, shadows and white balance.
6. Compare the result with the normal JPEG.
Ask whether the RAW version actually gave you something useful.
7. Use RAW selectively.
Once you understand where it helps, reserve it for those situations.
That last step is important.
How Much Storage Does RAW Need?
RAW files are substantially less convenient from a storage perspective than ordinary finished photographs.
Samsung does not specify one universal file size because it varies according to the camera, resolution and scene.
But the practical difference is obvious: if you photograph everything in RAW, your storage and backup requirements rise quickly.
This is especially relevant on a phone because photographs compete for storage with:
- 4K and 8K video
- Apps
- Downloads
- Offline media
- Documents
- Messaging attachments
RAW therefore has an ownership cost even when there is no separate monetary purchase.
The Best Reasons to Shoot RAW
Use Expert RAW when at least one of these is true:
- The lighting is difficult and you expect to edit.
- The photograph is important enough to justify post-processing.
- You need precise white-balance control.
- You want to recover or reshape highlights and shadows.
- You plan to make a substantial crop or print.
- You are photographing landscapes or architecture deliberately.
- You are experimenting with long exposures or astrophotography.
- You want manual control over exposure, focus or shutter speed.
If none of these apply, the normal camera is often the more efficient choice.
The Biggest RAW Mistake to Avoid
The biggest mistake is assuming that RAW automatically means better-looking photographs.
It doesn’t.
RAW generally looks less finished because it is intended to give you more control.
A normal Samsung photograph may initially look more impressive because the phone has already applied substantial computational processing.
The RAW file’s advantage becomes apparent when you take control of the image yourself.
That means RAW photography is partly a technical decision and partly a commitment to a workflow.
The Right Question Is Whether You Will Edit
The Galaxy Ultra’s RAW capability is most valuable when you think of the phone as a capture device rather than a complete imaging pipeline.
For everyday photography, Samsung’s conventional camera does the work of turning a scene into a finished photograph. That convenience is difficult to beat.
For important photographs, difficult lighting, deliberate compositions and creative work, Expert RAW gives you another option: capture the scene with greater control and make more of the final decisions later. Samsung currently supports Expert RAW on the S26 Ultra and saves Linear DNG 16-bit RAW alongside JPEG output, while also providing manual controls and specialized features on supported devices.
The most useful rule is therefore simple: shoot RAW when you have a reason to edit, not merely because the phone can shoot RAW. If the photograph needs to be captured quickly and shared immediately, use the normal camera. If the photograph matters enough that you want control over how its light, color and detail are ultimately rendered, that is when the extra information in a RAW workflow starts earning its place.
