The X2D II's screen shows a clean capture: highlights intact, histogram comfortable. Then you open the same file in Phocus 4.2 and it renders darker, with a different histogram and cyan clipping warnings that don't line up with what the camera showed you. The first instinct is that something broke: the metering, the file, or Phocus itself. Nothing broke. A reader (who had posted the same findings in a DPReview thread¹) wrote to me with exactly this, and his framing was better than most: he'd stopped trusting Smart Metering because record mode, playback, and Phocus all showed him something different, and with the camera in HDR mode he couldn't spot-meter his way out. Both observations are correct. The fix isn't a setting; it's knowing which of the three pictures is the file. 💡 ****A note on support:** This post represents my personal exploration and testing, not official technical support or guidance from Hasselblad. If you need assistance with your Hasselblad equipment, please contact Hasselblad directly: [customersupport@hasselblad.com](mailto:customersupport@hasselblad.com) for global support, [support.us@hasselblad.com](mailto:support.us@hasselblad.com) for the Americas, or visit hasselblad.com/support for regional options. > **Key finding:** The X2D II's live view, in-camera playback, and Phocus 4.2 are three different renders of one RAW, and only Phocus renders the actual file. HDR mode's forced Smart Metering deliberately holds exposure back by up to \~2.5 stops to protect highlights, so Phocus's darker render is the real, intended exposure. ## Why do record mode, playback, and Phocus all disagree? Because you are not looking at one image three times. You are looking at three renders built for three different jobs: - **Record mode (live view)** is built for composing and focusing. It doesn't always track your exposure. - **Playback** shows the camera's processed preview, tone-mapped to look good on the built-in screen. Its blinking clip warning reads from that preview too, which is why it can disagree with Phocus about what clipped. - **Phocus** renders the RAW itself through Hasselblad's color pipeline. This is the only one of the three that shows you the file. ![Diagram: one RAW file feeding three different renders, the X2D II record-mode live view, the in-camera playback preview, and Phocus 4.2, with only the Phocus render labelled as the file](https://storage.ghost.io/c/f5/ac/f5aca107-db6c-464b-b8b7-7b834c3c955f/content/images/2026/08/x2d-ii-clipping-three-renders.png) The same capture, rendered three ways. Only the Phocus render is the file. When my reader took the question to Hasselblad support, their answer (posted in full in the thread¹) was a compressed version of the same point: "The camera renders a preview as opposed to displaying the full RAW file which you will see in Phocus." That's correct, but it leaves out the two mechanisms that make the previews diverge, and those mechanisms are where the confusion actually lives. ## What record mode is really showing you The live view image is governed by a setting you may never have opened: **Exposure Simulation**, under Main Menu > Exposure Settings, not under Display where you'd expect it (X2D II manual, section 3.2). When simulation is active for your shooting mode, live view tracks the exposure you've dialed. When it isn't, the screen shows a brightness-optimized preview instead, built so you can compose and focus, not so you can judge exposure. Two behaviors compound this. The manual states that Exposure Simulation is automatically deactivated while autofocus is analyzing the subject, then reactivated after focus completes. In practice: the display brightens during your half-press, exactly when you're looking hardest at it. And the setting is scoped by exposure mode (the manual's options are "A/S/P/Auto" or "A/S/P/Auto/M"), so depending on how it's configured, an entire mode's live view may never reflect your dialed exposure at all. So record mode can genuinely look brighter than the exposure being set. Playback then shows the captured result without the composition aid, which reads as "the image got darker between record and play." No metering changed. Only the rendering did. Have you seen the guide? I've published Essential Phocus 4.x for Mac - 85 topics across 8 sections and 246 pages covering everything from HNCS color science to HDR workflows. It's the reference manual Hasselblad hasn't updated since 3.8\. It's $49, and updates are included. [Get it here ](https://payhip.com/b/6pqAt?ref=blog.tonalphoto.com) ## Phocus is darker because the metering did its job With HDR output enabled, the X2D II locks metering to Smart Metering and removes Spot, Centre Spot, and Centre Weighted entirely. That's not a bug my reader hit; it's how the camera works, and it's documented behavior (manual sections 2.4 and 2.7). In high-contrast scenes, HDR Smart Metering pulls exposure back from a neutral reading by up to about 2.5 stops, specifically to keep highlights from clipping. I covered why that trade is the right one for this sensor in [the highlight-metering post](https://blog.tonalphoto.com/hasselblad-x2d-ii-highlight-weighted-metering/): shadow recovery on a 15.3-stop sensor is essentially free, and clipped highlights are gone for good. The camera's playback preview is built to look pleasant on the 1400-nit screen, so you never really see that deliberate underexposure in the field. Phocus doesn't extend the same courtesy. It renders the RAW as metered, which means the darker image in Phocus is not a rendering error. It's the first honest look at the exposure the camera chose on purpose. The cyan marks are Phocus's Highlight Warning tool (a toggle, ⌃⇧H, light cyan by default) flagging what its current render treats as clipped, and that brings us to the checkbox. ## Unchecking HDR in Phocus doesn't remove clipping. It hides headroom. My reader noticed that turning the HDR checkbox off in Phocus made the clipping warnings shrink, which made HDR mode look like the culprit, as if the HDR render were boosting highlights into clipping. It's the other way around. With HDR unchecked, Phocus maps the whole file into the standard SDR range. The brightest tones get compressed toward white, the histogram fits neatly inside the familiar 0-255 view, and values that actually extend beyond SDR white get squeezed together at the right edge, where the clip indicator treats them as one undifferentiated "clipped" mass. With HDR checked, those same tones spread out into the extended range above SDR white, where the histogram's gray capability zone shows them as what they are: recorded highlight data your display may or may not be able to preview. The RAW held that range the whole time. The checkbox only decides whether Phocus shows it to you. ![Diagram comparing the Phocus histogram with HDR unchecked, where highlights pile against the right edge and read as clipped, and with HDR checked, where the same tones spread into the gray extended-range capability zone](https://storage.ghost.io/c/f5/ac/f5aca107-db6c-464b-b8b7-7b834c3c955f/content/images/2026/08/phocus-hdr-checkbox-histogram.png) Unchecking HDR does not remove clipping. It compresses the highlights into the standard range, where the clip indicator counts them as one mass. Phocus also has a second, separate highlight tool worth keeping distinct here: the **HDR Warning overlay** (View > HDR Warning). Its yellow and red regions map your display's headroom, not the file's data. Red means "your screen can't preview this tone right now," not "this tone is clipped in the file." Treating that overlay as a clipping indicator is the fastest way to talk yourself into pulling down highlights that were fine. ## The Mac brightness trap One more layer catches people who check their files on an HDR-capable Mac and still see more clipping than the camera showed: a Mac's HDR headroom is not fixed. macOS adapts it to display brightness and ambient light, so at normal working brightness you are usually not getting the display's full HDR range. Hasselblad's own advice is to lower monitor brightness for HDR work, and you can watch the mechanism directly: with the Phocus histogram open on an HDR file, drop your display brightness a few notches and the gray HDR capability zone expands to the right. Highlights that looked clipped at full brightness start showing recoverable detail. I walked through the full histogram workflow, including this behavior, in [Part 3 of the HDR series](https://blog.tonalphoto.com/phocus-4-hdr-workflow-histogram-levels/), and [Part 4](https://blog.tonalphoto.com/hasselblad-hdr-display-requirements/) covers which displays have meaningful headroom to give. ## How do you expose for HDR when you can't spot meter? That's the mechanics. Here is the practical answer to my reader's direct question, "how do you adjust exposure in HDR mode," in the two workflows that actually work. **Option 1: let Smart Metering do the job it already does.** HDR mode's forced metering is doing precisely what you would reach for spot metering to do: holding the histogram off the right wall. In high-contrast scenes it protects highlights by design, and the RAW almost always carries more highlight detail than the camera preview suggests. Shoot, then treat the Phocus render as ground truth and lift shadows there. On this sensor, that lift is clean. **Option 2: take manual control back by leaving HDR mode off at capture.** Turn HDR output off and Spot metering returns. Meter the highlight you care about, lock it with AE-L, recompose, shoot. Then enable HDR in Phocus afterward. The in-camera HDR toggle changes the preview, the metering, and the JPEG sidecar, and it never touches the RAW, so you lose exactly nothing by metering in SDR and going HDR in post. I covered the toggle's real scope in [the RAW+JPG post](https://blog.tonalphoto.com/x2d-ii-hdr-raw-jpg-capture-mode/). The four combinations of camera HDR mode and the Phocus HDR checkbox reduce to a simpler table than the menus suggest: | Camera HDR | Phocus HDR checkbox | What you get | | ---------- | ------------------- | ----------------------------------------------------------------------------------------------- | | On | Checked | Smart Metering's highlight-protective exposure; extended-range render showing the full headroom | | On | Unchecked | Same protective exposure; SDR render that compresses highlights and over-reports clipping | | Off | Checked | Your own metering (Spot available); extended-range render of the same full RAW | | Off | Unchecked | Your own metering; SDR render | The RAW in every row is a complete, full-range capture. The camera setting changes how the exposure gets metered and what preview you see; the Phocus checkbox changes how much of the captured range the render shows you. One precondition the table leaves implicit: the two camera-HDR-on rows require a mode where the toggle exists at all, meaning a JPEG- or HEIF-inclusive image format, single-shot drive, and a non-Manual exposure mode. The full grayed-out list is in the RAW+JPG post linked above. ## What to change in practice Treat the camera's screen as a framing tool and the Phocus render as the exposure reference. The preview is built to look clean, not to report the data. Before judging highlights in Phocus on a Mac, drop your display brightness and watch the histogram's gray zone open up. Full working brightness silently costs you HDR preview range. And when a scene demands precise highlight placement, don't fight Smart Metering for control it won't give you. Switch HDR off, spot meter, lock, shoot. Check the HDR box in Phocus when you get home. The only way to lose that headroom is to forget the checkbox. ## Sign up for The Tech Behind the Frame - Hasselblad edition Practical Hasselblad knowledge the official docs don't cover.
