IAPLC Prep Week 4: Lighting & Photography Tips

Welcome to Week 4! As we approach May, it's time to optimize your lighting for both plant health and photography. Your contest photo will be judged, not your actual tank, so photography matters as much as the aquascape itself.

Lighting for Plant Growth vs. Photography

These two goals require different approaches:

Growth Phase Lighting (Weeks 1-10)

• Intensity: High PAR (50-80 at substrate) for dense growth
• Duration: 8-10 hours daily
• Spectrum: Full spectrum with emphasis on red/blue for photosynthesis

Photography Lighting (Contest Photo Day)

• Intensity: Reduce by 20-30% to avoid hotspots and blown highlights
• Duration: Turn on 2-3 hours before shooting for natural plant orientation
• Spectrum: 6500-7000K for accurate color representation

Camera Settings for Aquarium Photography

Most IAPLC winners use DSLR or mirrorless cameras. Here are optimal settings:

Essential Settings

• ISO: 100-400 (lower is better for clarity)
• Aperture: f/8 to f/11 (ensures entire tank is in focus)
• Shutter Speed: 1/60 to 1/125 (use tripod for stability)
• White Balance: Custom or daylight (5500-6500K)
• Format: RAW for maximum editing flexibility

Composition Tips

• Position camera at tank's vertical center
• Ensure camera is perfectly level (use tripod with level)
• Fill frame with tank, minimize surrounding area
• Shoot straight-on, avoid angles

Water Clarity Techniques

Crystal-clear water is non-negotiable for IAPLC. Achieve it through:

One Week Before Photo Session

1. Activated Carbon: Add to filter to remove tannins and discoloration
2. Reduce Feeding: Minimize waste and cloudiness
3. Increase Water Changes: 30-40% every other day
4. Clean Filter Media: Remove debris without destroying beneficial bacteria

Day Before Photo Session

1. Final Water Change: 50% with temperature-matched water
2. Remove Surface Film: Use paper towel to absorb oil film
3. Clean Glass: Inside and outside, use aquarium-safe cleaner
4. Remove Debris: Turkey baster to remove particles from substrate

Photo Day Morning

1. Final Glass Cleaning: Ensure zero smudges or algae
2. Remove Equipment: Hide or remove heaters, CO2 diffusers if possible
3. Check for Floaters: Remove any plant debris or bubbles

Timing Your Photo Session

Plant Maturity Sweet Spot: 6-8 weeks after planting

Why this timing?

• Plants are established and healthy
• Carpets are filled in but not overgrown
• Stem plants are bushy but manageable
• Algae is under control (if maintained properly)

Time of Day: Shoot 2-3 hours after lights turn on when plants are fully oriented and pearling (releasing oxygen bubbles).

Post-Processing Guidelines

IAPLC allows basic editing but prohibits heavy manipulation:

Allowed

• Exposure adjustment (±1 stop)
• White balance correction
• Contrast and saturation tweaks (subtle)
• Cropping to improve composition
• Sharpening (moderate)

Not Allowed

• Adding or removing elements
• Cloning or healing tools
• Dramatic color shifts
• Compositing multiple photos
• Heavy filters or effects

Golden Rule: Your photo should accurately represent what judges would see if viewing your tank in person.

Common Photography Mistakes

• Shooting too early: Plants not mature enough
• Shooting too late: Overgrowth and algae issues
• Poor water clarity: Hazy or tinted water
• Visible equipment: Heaters, diffusers in frame
• Uneven lighting: Hotspots or dark corners
• Camera not level: Tilted perspective
• Over-editing: Unnatural colors or contrast

This Week's Action Items

1. Optimize lighting settings for photography
2. Practice camera settings and composition
3. Begin water clarity protocol (activated carbon, water changes)
4. Clean all glass surfaces thoroughly
5. Schedule your photo session for optimal plant maturity
6. Test shoot and evaluate results
