Capturing The Dome – Editing a Panorama Inside St Peter’s Basilica

Photographing Saint Peter’s Basilica: Why I Shot a Four-Frame Panorama

What do you do when your lens isn’t wide enough? Make a panorama.

This week we’re inside one of the world’s most iconic churches—Saint Peter’s Basilica in Rome. I’ve visited several times over the years, and the experience has changed dramatically. My first visit, about 30 years ago, was remarkably simple: you could just walk through the open doors. These days it’s a bit more complicated—while entry to the basilica itself remains free, you’ll need to pass through airport-style security queues outside. Want to climb the dome? That’s ticketed separately, running around €22 as of 2025.

The basilica took over 120 years to complete, with construction beginning in 1506 and finishing in 1626. Michelangelo took over as chief architect at age 71 and designed the magnificent dome, though he died before seeing it completed. Multiple architects and artists contributed over those decades, including Bramante, Raphael, and Bernini, making it one of the most collaborative architectural achievements in history.

But once you’re inside, all the logistics fade away. The interior is simply magnificent—an architectural photographer’s dream. I’m not a religious person myself, but I’ve always been fascinated by the history and architecture of places of worship. Saint Peter’s stands out even among the world’s great religious buildings. The scale, the craftsmanship, the light—it’s all designed to inspire awe.

Standing beneath the papal altar (officially called the Altar of the Confession), your eyes are naturally drawn upward into Michelangelo’s magnificent cupola. The ceiling was designed with this exact intention—to lift your gaze toward the heavens. The scale is genuinely overwhelming, and the detail is stunning even from this distance below.

Here’s the problem I faced: no single frame with the lenses I had with me could truly capture the full scope of this view. The cupola alone is enormous, and I wanted to include the ornate underside of the papal altar as well—the bronze baldachin with its twisted columns designed by Bernini. Using my Canon 17mm tilt-shift lens and its shift capabilities, I captured a four-frame panorama to encompass this breathtaking scene in a single image.

In this tutorial, I’ll walk you through my complete workflow—from the initial captures through Lightroom stitching and masking, all the way to fixing stitching anomalies in Photoshop. Let’s assemble this panoramic view from scratch.


THE PROCESSING WORKFLOW

The Challenge: Looking Up

From the thousands of images I captured in Saint Peter’s, I selected four specific frames shot from directly underneath the Altar of the Confession (also known as the papal altar). I was as close as I could physically get to it.

The Setup:

  • Looking straight up, elbows locked in to create a stable “human tripod”
  • Using the 17mm tilt-shift lens, I shifted down with each exposure to encompass both the ceiling and the underside of the papal altar
  • By stitching these together, I created an image I simply couldn’t achieve with a single frame

Step 1: Global Adjustments (Before Stitching)

After syncing all four images, begin with basic overall adjustments

Before merging the panorama, I apply overall adjustments so the stitched image already looks reasonable:

Exposure & Contrast:

  • Increased exposure slightly
  • Dropped highlights to preserve the wonderful light in the cupola
  • Increased contrast
  • Lifted shadows marginally
  • Dropped blacks and pushed whites (this push-pull increases both saturation and contrast)

Clarity & Sharpening:

  • Added 5-10 points of midtone contrast (clarity) for that “crunch” I like, especially when printing

Noise Consideration: Shot at ISO 1600, but the noise wasn’t that prevalent. I could denoise later using Topaz or DxO PureRAW if needed, but for now, left it alone.


Step 2: Understanding Panorama Projections

Determining the ideal projection for the 4 image panoramic stitch

Before stitching, Lightroom offers three projection modes. Here’s what they actually mean:

Spherical: Like pasting photographs onto a globe—good for really wide-angle shots or looking up

Cylindrical: Like wrapping photographs around a cylinder—vertical lines stay straight, but top and bottom may bend

Perspective: Like pinning photographs flat onto a wall—looks natural in the center, but edges can stretch

My choice: Cylindrical worked best for this image, keeping the vertical lines straight while encompassing the full scene. I unchecked “auto crop” to see all my options, then manually cropped after stitching.


Step 3: Selective Masking After Stitching

Once the panorama was merged, I used Lightroom’s masking tools to fine-tune specific areas:

  • This area was quite dark, so I painted a mask underneath
  • Increased exposure significantly to bring it to life
  • Lifted shadows to reveal detail
  • Warmed it up slightly (it was reading a bit cool)
  • Softened brush edges to blend naturally

The Cupola (Radial Gradient):

  • Dropped highlights to preserve the light streaming through
  • Reduced exposure slightly
  • Increased shadows
  • Pushed blacks down and whites up for contrast and color saturation
  • That lovely ray of light really came through

Side Alcoves (Brush):

  • Dropped highlights on the brighter right side
  • Added slight warmth to balance the cool tones

Mosaic Surrounds (Brush):

  • The mosaics around the cupola were slightly cool
  • Painted warmth into these areas for a more inviting feel

Bottom Pillars (Brush):

Final Global Adjustment:

  • Increased overall exposure slightly
  • Dropped blacks a touch more for punch

Step 4: Fixing Stitching Anomalies in Photoshop

Selecting a portion of the ceiling, (Cmd + J) jumping it to a new layer, and then using free transform to fix a stitching anomaly.

Using the lasso tool to select a new ‘plug’ to fix the stitching error. After transforming, create a composite layer of all layers, then use the Clone Stamp tool to blend the plug seamlessly before merging the layer down for the final output.

Even with perfect stitching, there were a couple of areas where Lightroom didn’t align the cupola edges perfectly. Here’s how I fixed them:

  1. Identified problem areas (zoom to 100% to spot them)
  2. Used Polygon Lasso tool to select around the misaligned section
  3. Command+J to jump that selection to its own layer
  4. Command+T to transform, then dragged the corner into alignment
  5. Command+Option+Shift+E to create a composite layer
  6. Clone Stamp tool to blend and clean up any remaining seams

This takes about 5 minutes and makes the final panorama seamless.

🧳 TRAVEL NOTES — VISITING ROME & ST PETER’S

Where I Actually Stayed (And Would Again)

Residenza Delle Arti — Boutique hotel near the Trevi district. Comfortable beds, excellent breakfast, great location. This is where I stayed on my last trip and I’d return without hesitation.


Where To Eat (The Real Recommendations)

Rome is full of culinary gems—and absolute tourist ripoffs. Do your research before you go. Here’s what actually worked for me:

Vigna Allegra — Wine bar near my hotel where I had an incredible tasting platter on two separate nights. That’s how good it was.

What to order around Rome:

  • Cacio e Pepe — Simple perfection (pecorino, black pepper, pasta water)
  • Amatriciana (try it at Armando al Pantheon)
  • Fiori di Zucca — Fried stuffed zucchini flowers, a true Roman treat. So very tasty.

Five Actually Useful Tips for Visiting Rome

Yes, you’ve heard some of these before. That’s because they’re true. Ignore them at your own risk.

1. Arrive Early at St Peter’s (But Here’s Why It Actually Matters)

The basilica opens around 7am, and weekdays are quieter. I took this shot in late afternoon, which also works—the key is avoiding mid-morning when tour groups descend. The light changes throughout the day, so if you’re serious about photography, visit twice.

2. Skip-the-Line Tickets: Book Direct

Lines can stretch for hours during summer or Jubilee years. I’ve used third-party skip-the-line services like Tickitaly with mixed results—some people report issues. You can still book directly with venues (as I did with the Colosseum). It may cost a bit more but it does remove the stress.

3. Pickpockets Are Real (Here’s The Actual Technique They Use)

Rome is generally safe, but theft is common around busy sites and public transport. The classic move: someone puts a begging note in front of you while their hand goes underneath into your open bag. Keep bags zipped and in front of you. Wallets in hidden pockets. Stay alert in crowds.

4. Shoulder Season Is Ideal

Spring (mid-March to May) and autumn (mid-September to November) offer mild weather and manageable crowds. You absolutely don’t want to be walking cobbled streets in 35°C summer heat while dodging selfie sticks.

5. Wear Proper Walking Shoes (I’m Serious)

Rome is best explored on foot, and the cobbled streets, expansive ruins, and irregular surfaces demand supportive footwear. I learned this the hard way. Your feet will thank you.
