Professional Tip

When shooting in situations with challenging light, consider using the histogram display (toggle in settings or assign to a custom button). That gives you a real-time view of your exposure distribution.

RAW+JPEG Capture

Pearla’s RAW+JPEG capture system is essential for photographers who want to maximise image quality while maintaining flexibility in post-processing. This powerful feature lets you capture both formats simultaneously, giving you the best of both worlds.

Understanding RAW+JPEG in Pearla

When shooting in RAW+JPEG mode, Pearla captures two versions of each image. The first is a RAW file, which gives you maximum editing flexibility. The second is a processed JPEG with your selected film profile and recipe settings applied. On supported devices, Pearla automatically uses Apple ProRAW format, providing additional computational photography benefits while maintaining the flexibility of RAW. Pearla captures standard RAW files on other devices, ensuring you still have complete post-processing control. Both raw formats are processed using Apple’s default image development pipeline. JPEG images bypass Apple’s pipeline and are developed using Pearla’s pipeline and your image processing settings.

RAW+JPEG Workflow

Remember that film profiles and recipes apply to JPEG only, leaving your RAW files untouched during capture. The JPEG preview allows you to monitor your creative decisions in real-time while maintaining the security of an unprocessed RAW file.

The dual-format capture opens up unique creative workflows. You can use JPEG files with your chosen film profile for quick sharing or when you’re satisfied with in-camera processing. Meanwhile, your RAW files remain available for images that need more extensive editing. This approach lets you compare processed and unprocessed versions to refine your recipes or maintain an unprocessed archive while delivering stylised JPEGs.

Your captured images appear as a single asset in the Photos app but contain both formats. This intelligent handling means you don’t need to manage separate files but retain all the benefits of both formats. You’ll have immediately shareable JPEGs with your chosen look alongside full-quality RAW files for professional editing, all while maintaining efficient storage management and simple image organisation.

You can access the raw files in two ways:

  1. Via the Photos app on a Mac.
  1. Import the image from the Photos library on iOS or iPadOS into an app that supports raw image processing.

Storage and Professional Considerations

While RAW+JPEG capture requires more storage than JPEG alone, the benefits may outweigh the storage cost.

Consider using RAW+JPEG for important shoots. The JPEGs provide immediate results with your chosen look, while the RAW files serve as digital negatives. That allows you to revisit and reprocess images as your creative vision evolves or when new processing tools become available. Think of it as having both a finished print and the original negative, but in digital form.

Film Emulation Profiles

Pearla’s film emulation system provides nine distinct profiles, each carefully crafted to deliver specific aesthetic qualities. These profiles allow photographers to achieve classic film looks directly in the camera.

There are two ways to change film emulation profiles:

  1. On the settings screen, you’ll find a list of all available profiles under ‘Image Processing’ -> ‘Film Emulation’. Tapping the empty circle on the left will enable the profile. Tapping on the title will open a screen with additional details about the profile and a preview image.
  2. Using the Film Emulation context, the control dial allows you to swipe through all available profiles. The viewfinder preview image will update in real time, and an overlay will show a preview of the selected profile.

Log Photography and Video

Pearla’s Log capture system, Pearl-Log, brings professional colour grading flexibility to both stills and video. By capturing images and video with expanded dynamic range and neutral colour reproduction, Pearl-Log gives you maximum control over your final look in post-production.

Understanding Pearl-Log

Pearl-Log captures images and video with a mathematically precise tone curve that preserves maximum detail in highlights and shadows. This approach differs from standard capture by postponing creative decisions about contrast and colour until post-processing. This flexibility empowers photographers and cinematographers with enhanced control over their final images.

Working with Log

When you enable Log mode in settings, Pearla shifts into a specialised capture state optimised for post-production flexibility. All film profiles and recipes are bypassed in this mode, ensuring clean, gradable footage. Log mode applies only to JPEG photos and video files, leaving RAW files unaffected.

The Log Settings screen provides essential controls for your workflow. Here, you can select your target colour space matching and upload custom 33-point LUTs. Your uploaded LUTs can be applied during image processing, streamlining your workflow while maintaining the benefits of Log capture.

Professional Colour Space Matching

We carefully crafted Pearl-Log’s colour science to integrate with professional workflows through precise colour space matching. When working with Pearl-Log, you can match your footage to Sony S-Log3 or Nikon N-Log colour spaces, ensuring seamless integration with footage from professional cameras.

This compatibility serves several crucial purposes. For cinematographers, it means Pearl-Log footage can be cut seamlessly with footage from professional cinema cameras. For photographers, it ensures colour accuracy when matching Pearla’s photos with photos and videos from professional cameras. The colour space matching system also means you can use industry-standard LUTs and grading presets designed for S-Log3 or N-Log, simplifying your post-production workflow.

Monitoring Your Image

Viewing Log footage can be challenging due to its intentionally flat appearance. Pearla addresses this through its Gamma Assist feature, which provides a corrected preview while maintaining Log recording. That makes composition and exposure evaluation more intuitive without compromising the benefits of Log capture.

Protect your highlight detail whenever possible for precise exposure control. Log capture provides extensive dynamic range, but maintaining clean highlights ensures maximum flexibility in post-production. The same monitoring tools in standard capture, including the histogram, remain in Log mode.

Professional Integration

Pearl-Log works consistently across all supported frame rates, resolutions, and codecs. The Log implementation remains consistent whether you’re capturing stills or video, working in standard or Open Gate format, or using different frame rates. This uniformity simplifies post-production and ensures predictable results.

Colour Grading Workflow

When working with Pearl-Log footage in post-production, treat it like any professional Log-encoded material. Begin by applying a technical LUT to convert from Log to your working colour space, then proceed with creative grading or follow a CST workflow in a colour grading software like Davinci Resolve.

Shutter Angle Control

Overview

Shutter angle control provides professional cinema-style motion rendering in video mode, offering precise control over motion blur and exposure.

Understanding Shutter Angle

Shutter angle is a traditional cinema concept that defines the relationship between motion blur and exposure in moving images. In film cameras, it refers to the angle of the rotating shutter disc that determines how long light hits the film. In Pearla, this concept is digitally implemented to give you precise control over motion rendering in your videos.

Shutter Angle Lock Feature

When to Use

Film Recipes

Creating and using custom recipes in Pearla extends your creative possibilities beyond the standard film profiles. A recipe allows you to craft and save your unique look, combining multiple adjustments into a single, reusable preset.

Understanding Recipes

A recipe begins with your choice of film profile as a foundation. From there, you can fine-tune numerous parameters to achieve your desired look. Think of recipes as your personal film stocks.

Creating Your First Recipe

Begin by accessing the recipe creation tool in Pearla’s settings screen. Select a film profile that closely matches your intended look—this becomes your starting point. From here, you can adjust:

The tonal characteristics, through shadow and highlight controls, allow you to shape the overall contrast of your image. Colour rendition can be refined through multiple tools: colour balance for overall shifts, colour chrome effect for subtle enhancements, and separate control over the blue channel.

Fine-tune the image’s appearance with saturation and vibrance controls. Midtone detail control lets you enhance or soften the rendering of textures and fine details.

For a finishing touch, add character through grain and bloom effects. Grain can be adjusted in size and intensity, creating anything from subtle texture to pronounced film-like grain. The five-level bloom effect can add ethereal highlights or a dreamy atmosphere to your images.

Working with Recipes

Your saved recipes appear in a dedicated list within the settings screen. Each recipe enhances Pearla’s core capabilities, but remember that recipes don’t affect images captured in Log Mode. This separation ensures that when you need a clean, gradable image, Log mode provides an unmodified starting point.

Tip

Consider creating specific recipes for different scenarios: one for portraits that emphasise clean skin tones, another for landscapes that enhance natural colours, or perhaps a high-contrast recipe for street photography. By building a collection of recipes tailored to your needs, you can quickly adapt to different shooting situations while maintaining consistency in your work.
