Besser geht's nicht. Auch mit dem Fokus-Stacking.

Dieses Bild wurde aus zwei Aufnahmen erstellt, die aus unterschiedlichen Blickwinkeln, Brennweiten und Entfernungen gemacht wurden.

Die Schritte mit PTGui sind einfach:

• automatisch Kontrollpunkte erstellen lassen, und alle Kontrollpunkte außerhalb des interessanten Bereiches (Tellers) entfernen
• ohne parameter a, b und c optimieren, also nur Blickwinkel und Gier-, Nick- und Rollwinkel, damit werden die verschiedenen Brennweiten automatisch erkannt und korrekt zusammengefügt

Die Bereiche in Fokus zur Verwendung grün malen (rote Bereiche dagegen werden ausgeschlossen):

Dadurch werden nur die jeweils scharf abgebildeten Bereiche verwendet:

Vor dem Teller

Alles vorbereitet. Fast zu ordentlich für etwas, das gleich im Topf verschwindet.

Gute Zutaten, kurz umgerührt. So beginnt Minestrone.

Alles ist drin. Jetzt wird aus Arbeit langsam Geschmack.

Precise timing is critical in analog photography, especially during the development process in the darkroom. This project presents a versatile darkroom timer built around the Arduino Uno R4 and Gamepad Input Shield, designed to support key photographic development tasks with tactile control and visual feedback. It features an 8x8 LED matrix for ambient illumination and implements five distinct modes: LED brightness adjustment, manual and timed enlarger control, chemical bath sequencing, and a general-purpose timer. Navigation is intuitive via joystick or button input, making it a practical and user-friendly tool for analog photography workflows.

This project uses the Gamepad Input Shield and Arduino Uno R4. Wiring details are available in the source code. The joystick or up/down buttons are used to switch between tasks, while left/right buttons adjust the state or settings.
The first 8x8 LED block is used to illuminate the darkroom.

The timer implements five tasks:

• LEDBrightnessTask: Adjusts LED brightness from 0 to 15.
• EnlargerOnOffTask: Manual control of the enlarger.
• EnlargerTimerTask: Timed control of the enlarger.
• DevelopStopFixTask: Three timers for develop, stop bath, and fix stages.
• GeneralTimerTask: A general-purpose timer starting from 0 seconds.

LEDBrightnessTask

Sets the brightness of the 8x8 darkroom illumination LEDs from min 0 to max 15.

EnlargerOnOffTask

Manual enlarger switch switched on.

EnlargerTimerTask

Timed enlarger switch.

DevelopStopFixTask

3 timers for develop, stop bath and fix.

GeneralTimerTask

General timer starting from 0s.

Arduino Darkroom Timer Github Project

This darkroom timer project combines modern microcontroller technology with the tactile simplicity of gamepad input to support essential analog photography tasks. Whether you are timing enlarger exposures or chemical baths, this tool offers consistent performance and flexibility for both amateur and professional darkroom enthusiasts. With five dedicated modes and intuitive controls, it provides a reliable and customizable solution for anyone working in a traditional darkroom. The open-source design invites further experimentation and adaptation. Whether you are refining your workflow or building your own version.

Start of a new journey.

Lab Scans

🧪 Developed and scanned by The Darkroom ¹ using the 'Enhanced' scan option (available choices: 'Standard', 'Enhanced', 'Super Scan').

The scans are saved as sRGB JPEGs and include a standard EXIF header with the following metadata in one APP1 marker:

• Image dimensions 3089×2048
• Scan date
• Embedded thumbnail: 160×120 pixels
• Resolution marker: Standard 72 DPI
• EXIF Version 2.20
• EXIF Tag 0x0131 ('Software'): EZ Controller 6.60.031 (160615)

The JPEG quality level corresponds to luminance and chrominance settings of 97, resulting in an average file size of approximately 5 MB.

And finally, these masterpieces boldly redefined blur and questionable exposure as forms of artistic expression. Some even chose to exist only halfway, lingering at the threshold of beginning or end.
