The blobs at the top left are the most visible ones, but
there actually are dust blobs across the entire frame.
And apparently the photographer wasan't even aware of
the dust, as the blobs are on all or almost all images.

Yup!
The dust is very conspicuous, and is going to need some major fixing in
post. That sensor is in dire need of cleaning, and the photographer should
have taken an emergency cleaning kit with him on that trip. When you know
that you are going to be in an environment with wind, dust, and sand, there
is no excuse for not being prepared. At a minimum a lot of care should be
taken with lens changes.

The camera is a DSLR with an optical viewfinder and I#m
guessing that the images were not inspected during the
trip to Algeria, otherwise the photographer would have
noticed the dust on the sensor.

Given the camera, I suspect that the photographer is oblivious of the
potential dust problem with all ILCs, DSLR, or MILC. It is probably his
first DSLR.

Actually, looking at the photos of previous trips (the
Namibia one of last summer for instance) the dust on the
sensor was already there, so it seems that the
photographer doesn't even know that the problem exists,
or simply doesn't care. or maybe likes that 'blobby'
look ;-)

If he is that oblivious to the potential dust problem, it is inexcusable,
and he should stick to using a compact.


At least one photographer made a great effort to breed and photograph dust.
