Introduction
One of the most discussed parts of Gary McKinnon’s UFO story is not the alleged object itself but the labels attached to NASA image files. McKinnon has repeatedly said that he found image folders containing versions described as “filtered and unfiltered” or “processed and unprocessed”, and that one image appeared to show a cigar-shaped craft. Because the underlying files were never preserved or released, sceptical analysis focuses on what those labels could realistically have meant inside a NASA imaging environment.

The key point is simple: in scientific and aerospace imaging, terms such as “raw”, “processed”, “filtered”, “unprocessed”, and similar labels are common parts of routine image workflows. On their own, they do not imply that an object was removed from a photograph, nor do they demonstrate a UFO cover-up. Without the original files, metadata, software environment and surrounding documentation, the labels are open to multiple interpretations.

When NASA labels look more alien than they are
McKinnon’s account has often been summarised as a discovery of NASA images in which UFOs were supposedly edited out. The evidential problem is that the public has never seen the files he described. What survives are recollections of folder names and image categories.

That distinction matters because image-processing terminology can sound far more dramatic than it is. NASA missions routinely work with multiple versions of the same image. Engineers, scientists and public-affairs teams may handle raw sensor data, calibrated images, noise-reduced versions, colour composites, contrast-enhanced copies and publication-ready products. Different labels can simply indicate different stages in that workflow. [NASA Earthdata+2NASA Science]earthdata.nasa.govAt higher levels, the data are converted into more useful parameters and formats. Standard Data…Read more…
A folder labelled “processed” does not automatically mean that content has been removed. More commonly, it indicates that data have been corrected, calibrated, colour-balanced, compressed or otherwise prepared for analysis or presentation. Likewise, “unprocessed” often refers to data closer to the original sensor output.

What filtered and unfiltered image labels might mean
The strongest sceptical response to McKinnon’s description is that the terminology itself is ordinary.
NASA’s own public explanations of image handling describe distinctions between raw and processed imagery, noting that processing may involve enhancing details, adjusting contrast, applying calibrations or converting instrument data into forms useful for scientific work. Raw images may also lack context, validation and calibration. [NASA Science+2NASA Science]solarsystem.nasa.govScience Raw images faqNASA ScienceRaw images faq - Solar System Exploration - NASAJun 22, 2022 — Processing images – that is, using software to enhance details…
Within such environments, “filtered” can refer to several routine operations:
- Noise reduction to remove sensor artefacts.
- Contrast enhancement to reveal faint features.
- Removal of cosmic-ray strikes or imaging defects.
- Selection of particular wavelength bands.
- Compression and optimisation for storage or distribution.
- Application of analytical filters used in scientific image processing. [NASA Earthdata+2NASA Science]earthdata.nasa.govAt higher levels, the data are converted into more useful parameters and formats. Standard Data…Read more…
Importantly, none of these uses requires the presence of a UFO. Scientific imaging systems often generate multiple versions of a file automatically, producing side-by-side datasets that may be labelled according to processing state. NASA’s published descriptions of image pipelines and data levels show that maintaining different stages of image processing is standard practice. [NASA Earthdata+2NASA Science]earthdata.nasa.govAt higher levels, the data are converted into more useful parameters and formats. Standard Data…Read more…
This does not prove that McKinnon misread the labels. It simply means that the labels themselves cannot carry the weight of the extraordinary conclusion sometimes attached to them.
Why image context changes interpretation
A recurring problem in UFO investigations is that isolated images often look more compelling than they do once their context is restored.
An image file sitting inside a directory tells investigators very little on its own. Analysts would normally want to know:
- Which instrument captured the image.
- When and where it was taken.
- Whether it was part of a calibration sequence.
- What processing software created each version.
- Whether the object appeared in multiple frames.
- Whether accompanying technical notes explained the feature.
Without that information, even genuine differences between two versions of an image can be misleading.
NASA’s publicly documented imaging systems routinely move data through multiple processing levels before they become scientifically useful or publicly distributed. A feature that appears in one stage but not another may reflect calibration, noise removal or artefact correction rather than deliberate concealment. [NASA Earthdata+2NASA Science]earthdata.nasa.govAt higher levels, the data are converted into more useful parameters and formats. Standard Data…Read more…
This is one reason why image specialists tend to focus less on dramatic folder names and more on provenance. The context surrounding an image usually carries more evidential value than the image label itself.
How sceptics test a dramatic label
Sceptics do not necessarily argue that McKinnon invented what he saw. Instead, they ask whether the interpretation follows from the available evidence.
A typical evaluation proceeds through several questions:
- Is the label independently verified?
In this case, no publicly available file system, screenshot or forensic copy has confirmed the exact naming convention beyond McKinnon’s account.

- Does the terminology have ordinary technical uses?
Yes. NASA and other scientific organisations routinely distinguish between raw, processed, calibrated and filtered imagery.

- Can the underlying files be examined?
No. The alleged images were never released for independent analysis. [WIRED]wired.comufo hacker tells what he foundWIRED'UFO Hacker' Tells What He Found21 Jun 2006 — 'UFO Hacker' Tells What He Found. The search for proof of the existence of UFOs landed…
- Are there alternative explanations requiring fewer assumptions?
Yes. Standard image-processing workflows account for the labels without requiring a UFO-removal programme. [NASA Earthdata+2NASA Science]earthdata.nasa.govAt higher levels, the data are converted into more useful parameters and formats. Standard Data…Read more…
From a sceptical perspective, the decisive issue is not whether NASA uses processed and unprocessed imagery—it unquestionably does. The issue is whether the specific image McKinnon described can be examined and shown to contain something extraordinary. Since the image has never been produced, the labels remain suggestive but unverified evidence.

The evidence value of the labels today
The image-label aspect of McKinnon’s story illustrates a broader problem in UFO controversies: technical language can appear revelatory when detached from its operational setting.
“Filtered”, “unfiltered”, “processed” and “unprocessed” sound significant because they imply that different versions of the same image existed. Yet in aerospace imaging, multiple versions are expected. NASA’s public documentation shows that raw and processed image products are a normal part of mission operations, data archiving and scientific analysis. [NASA Science+2NASA Earthdata]science.nasa.govNASA ScienceRaw Images FAQImaging scientists on NASA missions have access to original, uncompressed, science-quality images as soon as th…
As a result, the labels themselves neither prove nor disprove McKinnon’s wider UFO claims. Their evidential value is limited by the absence of the original files. For sceptics, that absence is the central fact: a potentially dramatic interpretation rests on terminology that can be explained by routine image-processing practices, while the underlying image remains unavailable for independent scrutiny.
