Log profiles and color grading for aircraft videos: from flat raw clip to finished look

An A350 taxis toward the runway in low evening sun, the sky behind it turns orange, the white side gleams – and in the finished clip, the fuselage is a featureless white surface while the sky breaks up into coarse color steps. Exactly for scenes like this, there are log profiles and color grading. This guide explains what log does technically, when it’s really worth it when filming aircraft, how to expose correctly and how to bring the clips step by step to a clean, consistent look in editing.

Log profiles: the short answer

A log profile is a logarithmic curve with which the camera stores brightness. Instead of preparing the image right away with high contrast and saturation, it lifts the shadows and compresses the highlights. That way, a larger part of the dynamic range the sensor captures fits into the video file. The result looks gray and flat on the camera display – and that’s exactly the intention.

Color grading is the work step that follows: you convert the flat footage to an output color space, match exposure and color and then give the clip a look. Log and grading therefore belong together. If you shoot in log and don’t grade, you simply have a worse image.

Why aircraft are such difficult subjects

At the airport, several extremes meet that push a standard profile to its limits:

• White fuselages in harsh sun. Many airlines rely on mostly white liveries, such as Lufthansa in its current design. These surfaces are among the brightest spots in the frame and are the first to clip.
• Dark details right next to them. Landing gear bays, engine inlets and the underside of the fuselage in its own shadow often sit many stops lower.
• Large, uniform sky. A gentle gradient from blue to light blue doesn’t forgive coarse jumps in tonal value. Banding is immediately visible here.
• Backlight and evening sky. Takeoffs into the sunset or approaches in front of bright clouds have enormous brightness differences. More on how to use such scenes creatively is in the guide to backlight photography.
• Brand colors. Airline liveries have clearly defined hues. If the red or blue of a livery shifts in the clip, spotters notice immediately.

A standard profile decides in the camera which details are lost. Log moves this decision into editing – provided you expose cleanly.

The manufacturers’ log profiles

Each manufacturer has its own log curves and usually its own color spaces to go with them. They’re not interchangeable: a clip in S-Log3 needs a different conversion than one in V-Log.

Manufacturer	Log profile	Typical camera families	Note for spotters
Sony	S-Log (S-Log2, S-Log3)	Alpha and Cinema Line models	widespread on mirrorless cameras with long telephoto zooms
Canon	C-Log (incl. C-Log2, C-Log3)	EOS R system cameras, Cinema EOS	different C-Log variants available depending on model
Panasonic	V-Log	Lumix system cameras, Varicam	often combined with 10-bit recording
Nikon	N-Log	Z system cameras	Nikon provides conversion LUTs
Fujifilm	F-Log	X and GFX cameras	own LUTs for the route to Rec.709
DJI	D-Log	drones and gimbal cameras	only fly legally – see the rules on drones at airports
Apple	Apple Log	newer Pro iPhones with ProRes	very large files, ideal with external storage

Which profiles your camera offers specifically and at which bit depth is in the manual. You’ll find an overview of the systems and their strengths for spotting in the comparison Canon, Nikon, Sony, Fujifilm, OM System. With drones, caution applies at airports anyway – the article on drones and airport rules summarizes the basics.

Is log worth it for you? The decision before the shoot

Log isn’t an upgrade you simply switch on. It costs storage space, processing power in the edit and above all time at the computer. So the question is: does it bring enough for your subjects?

For spontaneous clips from the fence, the normal video profile is often perfectly sufficient. How to proceed best for short formats is shown in the guide Plane spotting on YouTube Shorts, TikTok and Reels. For night shots, a look at Photographing aircraft at night is worthwhile – much of it applies equally to video.

Exposing correctly: the most important step

When grading, you can rescue a lot, but not blown-out highlights and not blacks sunk into noise. Exposure in log decides everything that’s possible afterward.

Don’t trust the display

The flat log image is deceptive. It looks darker and lower in contrast than the recording actually is. So use the camera’s aids:

• Zebras mark areas above a set brightness value. They show you immediately whether the fuselage in the sun is getting too bright.
• Waveform displays the brightness values across the width of the frame. You can see how far the brightest areas still are from the top end.
• Histogram provides a quick overview, but is less precise than the waveform.
• Log view assist (named differently depending on the manufacturer) shows you a converted preview on the display while the file continues to be recorded in log. That helps in judging contrast and color.

The fuselage is the yardstick

At the airport, a simple rule of thumb has proven itself: expose so that the brightest important surface just still has detail. That’s almost always a white fuselage side in the sun. The sky may blow out near the sun, the fuselage may not.

Many filmmakers deliberately expose log slightly generously, because the lifted shadows otherwise get noisy quickly. That makes sense – as long as the zebras on the fuselage stay calm. With a white aircraft against a dark background, there’s less room for this than with a colorful livery.

Setting white balance and shutter speed

Even though log gives you a lot of latitude: set the white balance manually instead of letting the automatic work. An automatic white balance that jumps during a pan when the fuselage enters the frame is hardly correctable cleanly in editing. How to spot and fix color casts is explained in Correcting white balance and colors.

You choose the shutter speed as with any video, based on frame rate and desired motion blur. In sun, that often means: ND filter, so the aperture doesn’t have to be closed down too far. You’ll find the matching basic settings in the guide Video settings for aircraft footage, and notes on higher frame rates in Slow motion for aircraft footage.

From log clip to finished grade: step by step

Whether you use DaVinci Resolve, Premiere Pro or Final Cut Pro – the logic is the same everywhere. DaVinci Resolve is popular with many spotters because even the free version comes with a complete color page with nodes, scopes and color management. An introduction to editing itself is offered by the guide Video editing for spotters.

The node order in Resolve

In DaVinci Resolve, you work with nodes that pass the image along from left to right. A proven, simple structure looks like this:

Node	Task	Typical tools
1 – Input	Convert log to the working color space	color space transform or manufacturer LUT
2 – Balance	Exposure, black and white points, white balance	Lift, Gamma, Gain, Offset
3 – Contrast	Adjust overall contrast and saturation	Curves, Contrast, Saturation
4 – Corrections	targeted adjustments, such as sky or livery colors	Qualifier, Power Windows
5 – Look	consistent mood	Curves, Color Warper, creative LUT with reduced opacity

If you work consistently with color management, you can skip node 1, because the conversion happens in the project. What matters is only that conversion and look aren’t mixed in a single LUT – otherwise you can no longer correct exposure independently of style.

Aircraft-specific grading tips

The general rules apply to every video. With aircraft, though, there are a few special features to watch for.

• Keep liveries true. A well-known airline color is a recognition feature for spotters. After the look, check whether the brand color is still right and correct it specifically with a selection if needed rather than across the whole image.
• Don’t overdo the sky. More saturation in the blue quickly looks artificial and amplifies banding. Better to darken subtly than to saturate strongly.
• Don’t sharpen away heat haze. Shimmering air above the asphalt can’t be repaired in grading. Too much sharpening only makes it more visible. How to avoid it at the time of shooting is explained in Avoiding heat haze.
• Don’t neutralize evening light. A landing in the golden hour lives from its warmth. A completely neutral white balance takes away exactly what makes it special.
• Headlights and reflections. Landing lights, strobes and reflections are often the brightest points in the frame. That they clip is normal and acceptable – as long as the fuselage next to them keeps its detail.

LUTs: a tool, not a magic button

LUTs are handy but often used wrongly. Basically, there are two kinds:

• Technical LUTs convert a specific log profile into a target color space. They usually come from the camera manufacturer and only work correctly if the exposure is right and the input matches the profile.
• Creative LUTs lay a style over an already converted image. They’re built for certain starting conditions and don’t automatically look on your footage the way they do in the promo image.

A good compromise: use creative LUTs only on a layer of their own and reduce their opacity. That way, the look stays subtle and the basic correction underneath stays untouched.

Monitor, export and platforms

Your grade is only as good as the screen you judge it on. An uncalibrated monitor with a blue cast leads you to make warm clips even warmer – and you only notice that on other devices. How to get a handle on that is described in Calibrating your monitor.

On export, platforms recompress your video. Fine gradients in the sky suffer first. A higher export quality helps limit the damage. Check the result after uploading on a smartphone, because that’s where most viewers watch.

If you film with a smartphone, the same principles apply on a smaller scale. You’ll find notes specifically on that in Shooting aircraft videos with your smartphone. And think about the amount of data: log footage at high bit depth fills memory cards and hard drives quickly. A well-thought-out backup strategy protects your raw data.

Common mistakes in color grading aircraft videos

• Publishing log without conversion. Gray, flat clips are not a style but unfinished footage.
• Choosing the wrong conversion. An S-Log3 clip with a V-Log LUT gets wrong contrast and colors.
• Exposing by the display. The flat log preview image invites misexposure – zebras and waveform are more reliable.
• Look before correction. If you put the creative LUT on first and then correct, you fight against it.
• Styling every clip individually. A video with five different looks feels restless. Better a consistent line across all scenes.
• Too much saturation. Strongly saturated skies and liveries quickly look garish on a smartphone.

If you’re starting out with log, you should also keep composition in mind: a perfectly graded clip with a tilted horizon or a cropped tail still won’t convince. The guide Composition in aircraft videos fits here, and the fundamentals overview is offered by Shooting plane spotting videos. For planning the light in advance, Planning the sun position helps.

Conclusion

Log profiles are a powerful tool for aircraft videos because they make manageable exactly the extremes that constantly occur at the airport: white fuselages in the sun, dark landing gear, large areas of sky and backlight. The gain only comes with 10-bit, clean exposure on the brightest part of the fuselage and a clear workflow in editing: first convert correctly, then balance, then match and finally set the look. For night clips, flat light or quick short videos, the standard profile remains a fully valid alternative.
