The read-me is dated June 2, but the installer only landed on Hasselblad's download servers on June 3 (the dmg's last-modified timestamp). The notes lead with new features, but if you read this blog you already know the only question that mattered going in: are the two regressions that made 4.1.2 a version to avoid actually gone? They are. I tested both on an X2D II 100C, and 4.2 clears the pair that had this blog telling Hasselblad shooters to stay on 4.1.1 since April. Phocus 4.2 is available now: [download Phocus\_4.2\_Mac.dmg directly](https://cdn.hasselblad.com/software/Phocus%5Ffor%5FMac/4.2/Phocus%5F4.2%5FMac.dmg?ref=blog.tonalphoto.com) (746 MB), or get it from [Hasselblad's Phocus page](https://www.hasselblad.com/phocus/phocus-for-pc-mac/?ref=blog.tonalphoto.com). 💡 ****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:** Phocus 4.2 fixes both 4.1.2 regressions: the default color preview now renders correctly and matches the export, and a full-size JPEG from an X2D II 100C exports at native 11656×8742, not the silent 7000×5250 downscale. New in 4.2: redesigned SDR/HDR export presets, a brush eraser, and bidirectional highlight and shadow sliders. ## Are the two 4.1.2 regressions fixed? Yes, both. I reopened the same X2D II 100C raw I used to document the [color preview regression](https://blog.tonalphoto.com/phocus-4-1-2-color-preview-regression/) and ran the same checks. The color preview path is fixed. In 4.1.2, every Hasselblad raw opened with a flat, desaturated default preview, and the correct rendering only appeared when you switched the hidden Reproduction tool's Working Space from Hasselblad RGB to Hasselblad L\* RGB. In 4.2 the default preview is already correct. Toggling Working Space barely changes the image, and a 16-bit TIFF export matches what the viewer shows. The split between a wrong preview path and a correct export path is closed. The export-size bug is fixed too. In 4.1.2, every export capped at 7000×5250 regardless of preset, a uniform 0.6005 downscale that hit [JPEG, TIFF, and HEIF alike](https://blog.tonalphoto.com/phocus-4-1-2-jpeg-export-size/). In 4.2 a full-size JPEG of the same 100-megapixel raw comes out at 11656×8742, the body's native output resolution. I confirmed full size specifically and did not re-test every Restrict Pixels value, but the Dimensions code path is honoring the preset again. For the record, Hasselblad engineering reproduced the color preview bug back in April and committed a fix for a later release. Phocus 4.2 is that release. Researching and writing the blog and page posts I produce takes up a lot of my time and costs me money for software subscriptions, tooling, and other incidentals related to running a business.

The biggest change is export. **Redesigned export presets.** The Output Presets dialog has been rebuilt around SDR and HDR color profiles. New in 4.2, it splits presets into two labeled groups: a built-in Hasselblad Presets list and a separate Custom list. Each preset now carries its own SDR Output Profile and HDR Output Profile, so a built-in preset like JPEG Full Size ships with sRGB for SDR and Display P3 for HDR, and your custom presets hold their own pair. A mixed batch then exports predictably instead of forcing one profile onto everything. The original Ultra HDR JPEG preset is gone from the built-in list, so if you had a workflow pointed at that named preset, you will rebuild it around the new dialog. Update: testing shows there is nothing to rebuild. Exporting an HDR-mode image with any plain JPEG preset now produces an Ultra HDR JPEG automatically; the evidence is in [Where the Ultra HDR JPEG Preset Went in Phocus 4.2](https://blog.tonalphoto.com/phocus-4-2-ultra-hdr-jpeg-preset/). **Brush mask eraser and invert.** The Brush Mask tool gains an eraser and one-tap selection inversion, the same two refinements that [came to Phocus Mobile 2 in v4.3.0](https://blog.tonalphoto.com/phocus-mobile-2-v4-3-portrait-mask/). Overpaint a mask, erase the excess. Brush the subject, invert to work the background. **Negative highlight recovery and shadow fill.** Highlight Recovery and Shadow Fill now accept negative values, so each slider works in both directions for finer control at the bright and dark ends. I have not tested how far the negative range extends in practice, so treat that as documented behavior until I confirm it. **In-app update notifications.** Phocus now tells you when a new version is available. Until now there was no signal inside the app, and you found out a release had shipped by checking Hasselblad's website. A built-in notification is small, but it is overdue for software that ships meaningful point releases. **Two more from the read-me:** improved highlight rendering for exported HDR HEIF and Ultra HDR JPEG images, and improved EXIF data embedded in exported files. The import-preset fix gets its own write-up, including how to tell which preset is actually active: [Phocus 4.2 Fixed Import Presets but Won't Tell You Which One.](https://blog.tonalphoto.com/phocus-4-2-import-presets/) ## Should you upgrade? For most users, yes. The two regressions that made 4.1.2 a version to avoid are both fixed, which removes the reason this blog spent the last two months telling Hasselblad shooters to hold on 4.1.1\. The export-profile work is a real improvement for anyone juggling SDR and HDR output, and the brush eraser is the kind of small change you feel every editing session. One caveat. I have verified the two known regressions and exercised the headline features, not every code path in the release. A point update can introduce new issues as easily as it resolves old ones, and I will report anything I turn up. If you upgrade and run into trouble, Hasselblad keeps the 4.1.1 installer on their support site, so the fallback is still there.
