Post-Processing and Workflow flashcards for Photography

25 of 50 cards from the Post-Processing and Workflow deck — real questions with worked answers.

1. What is a RAW file in digital photography?

   A file containing the unprocessed (or minimally processed) data captured directly from the camera sensor, with no in-camera white balance, sharpening, or compression baked in. It must be 'developed' in software such as Lightroom or Capture One before final output.

2. Compare the bit depth of RAW and JPEG files and the number of tonal levels per channel each provides.

   RAW files are typically 12- or 14-bit, giving $2^{12} = 4096$ to $2^{14} = 16384$ tonal levels per channel; JPEG is 8-bit, giving only $2^{8} = 256$ levels per channel. The extra depth in RAW allows far more aggressive editing before banding appears.

3. What are the three main advantages of shooting RAW over JPEG?

   1) Greater dynamic range and highlight/shadow recovery; 2) White balance and other settings can be changed losslessly after capture; 3) Higher bit depth (more tonal data) for smoother edits. Trade-offs: larger files and mandatory post-processing.

4. What type of compression does JPEG use, and what is its main consequence for editing?

   JPEG uses lossy compression: image data is permanently discarded to reduce file size. Repeated saving and heavy editing introduce compression artifacts and banding, so JPEG offers little latitude for correction.

5. What does 'non-destructive editing' mean in a RAW workflow?

   The original RAW data is never altered; edits are stored as a set of instructions (in a catalog or XMP sidecar file) applied on export. You can revert or change any adjustment at any time without quality loss.

6. What is the sRGB color space and when should it be used?

   sRGB is the smallest standard color space and the default for the web, most monitors, and consumer printing. Use it for any image destined for online display or unmanaged devices to ensure consistent color.

7. How does Adobe RGB differ from sRGB, and what is its typical use case?

   Adobe RGB has a wider gamut than sRGB, especially in greens and cyans (covering roughly 50% of visible colors vs. about 35% for sRGB). It is used for professional printing workflows, but images must be converted to sRGB before web display or colors will look dull.

8. What is ProPhoto RGB and what precaution must be taken when editing in it?

   ProPhoto RGB is an extremely wide-gamut working space that exceeds even most printable colors (parts of it fall outside human vision). Because the gamut is so large, you must edit in 16-bit; in 8-bit the widely spaced tonal steps cause banding/posterization.

9. Rank sRGB, Adobe RGB, and ProPhoto RGB from smallest to largest gamut.

   sRGB $<$ Adobe RGB $<$ ProPhoto RGB. Rule of thumb: sRGB for web output, Adobe RGB for print output, ProPhoto RGB as a wide working space during editing (in 16-bit).

10. Why is monitor calibration essential in a post-processing workflow?

    Uncalibrated monitors display inaccurate color, brightness, and contrast, so edits made on them will not match prints or other screens. Calibration measures the display with a hardware device and builds an ICC profile so colors are rendered accurately and consistently.

11. What hardware device is used to calibrate a monitor, and how does it work?

    A colorimeter (e.g., Calibrite/X-Rite, Datacolor Spyder) is placed on the screen while software displays known color patches; the device measures the actual output and generates a correction ICC profile for the display.

12. State the standard target values for white point, gamma, and luminance when calibrating a photo-editing monitor.

    White point D65 ($6500\ \text{K}$), gamma $2.2$, and luminance around $100\text{–}120\ \text{cd/m}^{2}$. Monitors should be recalibrated regularly (roughly every 2–4 weeks) because output drifts over time.

13. What is 'culling' in a photography workflow?

    The process of reviewing all imported images and selecting the keepers while rejecting duplicates, misfires, and technically flawed shots (missed focus, bad exposure, closed eyes) before any editing begins. It should be fast and decisive to save editing time.

14. Describe a best-practice import routine for new photos.

    Copy cards to a consistent, dated folder structure (e.g., Year/Date-Event), apply a batch rename, add copyright metadata and base keywords on import, generate previews, and make a second backup copy of the originals before formatting the memory card.

15. What three marking systems do programs like Lightroom provide for culling and organizing?

    Flags (pick/reject), star ratings (1–5), and color labels. A common workflow: first pass with pick/reject flags, second pass adding stars to ranked keepers, color labels for workflow status (e.g., to retouch, delivered).

16. Differentiate EXIF and IPTC metadata.

    EXIF is technical data written automatically by the camera (shutter speed, aperture, ISO, lens, date, GPS). IPTC is descriptive data added by the photographer (creator, copyright, caption, keywords, location names) for identification and licensing.

17. What is the purpose of keywording, and what is a hierarchical keyword?

    Keywords are searchable descriptive tags that make images findable in large libraries. Hierarchical keywords nest terms (e.g., Animal > Bird > Eagle) so tagging the child automatically implies the parents, keeping catalogs organized and searches powerful.

18. What is an XMP sidecar file?

    A small companion file stored next to a proprietary RAW file that holds metadata and edit instructions (keywords, ratings, develop settings) without modifying the original RAW. It lets edits and metadata travel between applications.

19. State the 3-2-1 backup rule.

    Keep 3 copies of your data, on 2 different types of media (e.g., internal drive + external drive), with 1 copy stored off-site (or in the cloud). This protects against drive failure, theft, and local disasters like fire.

20. Why is RAID not a substitute for a backup?

    RAID provides redundancy against a single drive's hardware failure, but all copies live in one device: accidental deletion, file corruption, ransomware, theft, or fire destroys everything simultaneously. True backups are separate, ideally versioned and off-site copies.

21. Distinguish 'backup' from 'archiving' in a photography workflow.

    Backup is an ongoing, synced copy of active working files for disaster recovery. Archiving is the long-term storage of completed/finalized work moved off the working system, organized for future retrieval, typically on redundant drives or cloud cold storage and refreshed periodically as media ages.

22. What does the Exposure slider in a RAW editor primarily affect, and what does a change of $+1$ corresponds to?

    It shifts overall image brightness with the strongest effect on midtones. Each $\pm 1$ adjustment equals $\pm 1$ stop (EV), i.e., a doubling or halving of brightness: a change of $n$ stops multiplies light by $2^{n}$.

23. What does an S-curve on the tone curve do to an image?

    It raises the highlights (upper-right of the curve) and lowers the shadows (lower-left), increasing midtone contrast and color saturation. An inverted S-curve does the opposite, flattening contrast for a matte look.

24. How do you read a histogram to check exposure, and what does 'clipping' mean?

    The histogram plots pixel counts from pure black (left) to pure white (right). Data pushed against either edge is 'clipped'—detail irrecoverably crushed to black (left) or blown to white (right). Aim to retain data within both ends unless clipping is a deliberate choice.

25. What is white balance, and how does the Kelvin scale relate to warm and cool light?

    White balance neutralizes the color cast of the light source so whites appear white. Color temperature is measured in Kelvin: low values (e.g., $\approx 2700\text{–}3200\ \text{K}$, tungsten) are warm/orange light; high values (e.g., $\approx 7000\text{–}10000\ \text{K}$, shade) are cool/blue. Daylight is around $5500\ \text{K}$.
