Brighten shadows and the fuselage underside, recover highlights

The Airbus comes in clean on approach, the focus is sharp, the registration is legible – and yet something is off. The top of the fuselage glows almost white, while engines, landing gear and belly sink into a dark gray. Everyone who shoots landings in sunshine knows exactly this problem. In this guide you will learn how to brighten shadows and the fuselage underside while recovering the highlights, in which order to use the sliders and where the line runs between clean processing and an artificial HDR look.

Brightening shadows and recovering highlights: the short answer

You work from top to bottom: first you set the overall brightness, then you pull back highlights and whites until the bright fuselage shows structure again. Only after that do you open the shadows – globally only moderately, and for the fuselage underside selectively with a mask or a brush. Finally you reset the black point so the image does not look flat, and check the edges for halos. The basis for all of this is a RAW file, because only it has enough headroom in bright and dark tones.

Why the order matters so much: every shadow correction also changes the midtones and so indirectly the look of the highlights. If you rip open the shadows first and then rescue the highlights, you go around in circles and almost always end up with a flat, gray image.

Why aircraft are so difficult

An airliner is a stress test for your sensor’s tonal range. Many airlines fly with mostly white fuselages – the article Why aircraft are painted white explains why. White reflects the sun strongly, and the curved top of the fuselage sits in direct light when the sun is high. The underside, on the other hand, turns away from the light and only gets scattered light from the ground and the sky.

Then there is the perspective. On a landing you often shoot from below at an angle, straight at the shaded side. On taxi shots and takeoffs you see more of the side, but there too the engine inlets, gear bays and the area under the wings sit in shadow. The differences between approach and takeoff shots are described in more detail in the guide Landings or takeoffs?.

The result is a dynamic range that the eye handles effortlessly but the photo does not. If you expose so that the white fuselage still has detail, the underside sinks into black. If you expose for the underside, the fuselage blows out. Editing has to solve this balancing act after the fact.

When the problem is biggest

How strong the effect is depends mainly on the sun position. When the sun is high, the belly is completely in shadow. With low sun in the morning and evening, the light still hits the underside from the side. How to choose spot and time accordingly is covered in the guide Planning around the sun position; why the edges of the day are so popular is explained in Golden hour and blue hour.

What “recovering highlights” really means

Before you touch any sliders, it is worth looking at what is still in the file at all. Every pixel of a color image consists of three channels: red, green and blue. An area can look white on screen even though only one or two channels hit their upper limit. Then information is still there, and processing software can reconstruct brightness and color from the remaining channels and neighboring pixels.

If, on the other hand, all three channels are clipped, there is nothing left to rescue. The documentation of the free RAW converter darktable explicitly describes its reconstruction methods as only plausibly masking large, fully clipped areas, not truly repairing them. For you this means: a completely blown-out fuselage stays a structureless area, even if it is gray instead of white after the correction.

State in the image	What is still possible	What you can do
Fuselage very bright, histogram just barely not touching the right edge	full detail present	lower highlights and whites slightly
individual channels clipped (often a slight color shift)	structure partly reconstructable	lower highlights noticeably, use the program’s reconstruction
all channels clipped, large area	no real structure left	keep the area neutral, cull the image if necessary
underside dark but not black	detail present in the RAW	open the shadows, plan for noise reduction
underside pure black	hardly any usable data	can only be brightened very little, quickly looks noisy

This is exactly where the advantage of RAW shows. The JPEG your camera shows on the display has already been processed with contrast and a tone curve and has less room to work with. The RAW file often still holds detail in areas the camera preview already marks as white. You can find more on this basic question in the comparison RAW or JPEG for plane spotting?.

The order in practice

The following steps work in Lightroom, Capture One, darktable and most other RAW converters – the sliders are just named slightly differently. An overview of the programs is given in the comparison Capture One, Lightroom and DxO, and the article Free photo editing for spotters collects free alternatives.

How these steps fit into the complete workflow from import to export is shown in the guide Editing aircraft photos. For Lightroom users there is a dedicated tutorial, the Lightroom workflow for aircraft photos, including syncing across whole series.

Brightening the fuselage underside selectively

The global shadows slider affects all dark areas in the image: trees, fence, cloud shadows, the apron. For the fuselage underside you usually need more effect than you want to inflict on the rest of the image. That is why the local correction is the real tool.

Subject mask: the quick way

Modern programs detect the main subject automatically. With aircraft this usually works well, because the fuselage stands out clearly from the sky. On this mask you apply a slight lift of shadows or exposure. Advantage: the sky stays unchanged and the brightening affects only the aircraft. But check the mask edge – on taxi shots with a busy background or heat shimmer, the detection occasionally misses.

Brush or gradient: the precise variant

If you really want to brighten only the belly, not the already bright top, a brush with a soft edge or a graduated filter from bottom to top is the more exact solution. On an approach shot you place the gradient so that it is at full strength at the bottom edge of the fuselage and fades out at about the height of the window belt. Many programs let you combine a mask with a luminance range selection. That way the correction inside the gradient affects only the dark tones.

Tone equalizer instead of brute force

Some converters offer tools that distribute brightness by tonal zones. The tone equalizer in darktable, for example, works with an edge-preserving mask that divides the image into areas of similar brightness, and changes the exposure per brightness zone. According to the documentation, local contrast is largely preserved. For aircraft this is appealing: you can lift the deep zones selectively without flattening the fuselage structure.

The three typical side effects

Every brightening has its price. If you know the side effects, you recognize sooner when enough is enough.

Halos at the fuselage edges

A bright fringe above the top of the fuselage or a dark edge below the belly are the classics. They occur with tools that work with blurring and local contrast when they are set too strongly. The darktable documentation names exactly these dangers for its shadows and highlights module: halos, exaggerated local contrast in the highlights and a blue shift in the shadows at strong settings. Remedies: back off the sliders, set mask edges softer or more precisely, and always check the result at full resolution.

Noise and color casts in the shadows

In dark areas of the image the signal-to-noise ratio is unfavorable. If you brighten them heavily, the noise becomes visible – often as colored speckle in gear bays and under the wings. Shadows also like to take on a bluish tone, because they are lit mainly by the sky. With heavily opened shadows, targeted noise reduction is therefore part of the job; the article Noise reduction with AI denoise introduces modern AI methods for this. You fix the color cast locally with a slightly warmer color temperature in the mask – more on this in the guide White balance and correcting colors.

The flat HDR look

When highlights are pulled down to the maximum and shadows pushed up to the maximum, the image loses its depth. An aircraft lives from light and shadow on the curve of the fuselage. If everything becomes equally bright, it looks cut out and pasted onto the sky. A bit of shadow under the fuselage is not a flaw but shows that the sun was shining.

Special cases at the airport

Big aircraft with long sides

On an Airbus A380 or a Boeing 747-8, every unevenness stands out because the side is so large. A subject mask that brightens the entire fuselage often looks more natural here than a brush that catches only the belly and leaves a visible boundary on the side.

Dark liveries and special liveries

Not every aircraft is white. On dark blue or black fuselages the problem partly reverses: the side is already dark, and the underside is barely distinguishable from it. Here the shadows slider helps less than a slight lift of the midtones via the tone curve. On colorful special liveries you should also make sure that brightened color areas do not tip over in saturation.

Backlight

When the sun is behind the aircraft, the whole side facing you is in shadow. Then every shadow correction quickly hits its limits. It is often more honest to accept the mood or to deliberately create a silhouette – the article Backlight in aircraft photography offers ideas for that.

Photo databases and screening

If you submit your images to platforms like JetPhotos, you quickly run into this topic during screening. Both areas of the image that are too dark and visible traces of editing such as halos or heavy noise can lead to a rejection there. The exact criteria differ by platform; you will find an overview in the articles Common rejection reasons in photo screening and Editing photos for JetPhotos and others. As a rule of thumb: the underside has to be recognizable, but the image still has to look like sunlight.

Reduce the problem at the shot

The most effective shadow correction is the one you don’t need. Three things help right at the fence:

• Shoot RAW: Only then do you have the headroom this guide assumes.
• Expose for the highlights: Better to expose a little tighter so the white fuselage doesn’t clip. Dark areas are easier to open in RAW than blown-out ones are to recover. Which camera settings have proven themselves is covered in the guide Camera settings for plane spotting.
• Choose light and spot: Low sun and a spot with the sun at your back noticeably tame the contrast. At the Munich Airport visitors’ hill (Besucherhügel) or the Hamburg Airport “Affenfelsen” viewing mound it pays to match the time of day to the direction of the light.

With light cloud cover, the sky also acts like a big diffuser that brightens the underside too. Gray days are therefore often more forgiving for this problem than brilliant sunshine.

If you are editing whole approach series with the same lighting, you develop one image carefully and transfer the settings to the others. How to do that efficiently is shown in Editing series photos efficiently. But always check local masks after transferring, because the aircraft sits slightly differently in every image.

Conclusion

An aircraft in the sun demands a balancing act from editing: the white fuselage needs restraint in the highlights, the shaded underside needs brightening. If you protect the highlights first, open the shadows only moderately globally and selectively locally, and then reset the black point, you get images with detail on top and underneath without looking flat. Halos, noise and a blue cast are the warning signs that you have gone too far. And most of it can be defused right at the fence: RAW, tight exposure and the right light.
