As you well know, different news readers treat them in different ways.
What it might look like to him need not be the same as the way it
looks to you.

nospam ... *my* delimited posts of the OP's URL post and read fine, this
doesn't give me any inkling of how it reads and reposts on *other* software

as I mentioned before there is no configuration of some text editors to
see LF and/or CR and/or EOL and/or other formatting ... so why should I
be able to know the difference in a newsreader, *unless* you let me know
how my editor's posts reads on your reader

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.

That assumes he knows how to use that kit (I don't).

it's never too late to learn. read the instructions

No such instructions on mine. They say to bring the camera to the
service shop.

what cleaning kit did you buy that did not include instructions??

I bought a camera.


or do a search on
how. there are plenty of detailed explanations and even videos. it's
not difficult. even just one squeeze of a rocket blower would make a
dramatic improvement.

Maybe he takes the
camera to a shop to be cleaned by a professional back home that knows
how to do it, and he wouldn't dare try to do it himself, even less on a
trip.

or maybe he doesn't care.

You do not know that.

it's quite clear he doesn't care, else he wouldn't have posted a photo
full of dust spots which looks like utter ****.

Not to me.


Now there’s your problem. ;-)

I don't have a problem :-D

(and no, there is no dust visible on my photos)


Maybe he posted the photos for his family and friends to see his trip,
not for Internet at large to see. It happened to me, I posted some
photos for the family on G+, and after some months I started getting
comments from unknown people. I promptly removed the photos.

excellent, except that the topic is cleaning kits.

No, it is "bad sensor dust". I never bought or implied I had bought a
cleaning kit.

did you buy anything else?

Whatever was in the box :-)

seriously? that photo was overwhelmed with dust spots.

So? Maybe you were not the intended target.

If he does not know how to go about cleaning the sensor on a DSLR, or MILC,
he, and anybody who owns one should invest in the basic tools, correct size
swabs, PEC pad, a Giottos Rocket, a bottle of Eclipse Fluid, and a
magnifier with some sort of illuminator.

I don't have any of that, nor my friends. I don't even know what they are.

All it takes to find out what 'they are' is to search, and then buy. Amazon
should lead you right to those items. Then you will have more knowledge
than your friends.

I'll wait till I can see someone doing it.



Then make the effort to learn how to go about cleaning a sensor, even on
the road away from home. Especially if one is in an environment where dust
contamination is likely.

I had no idea about dust, and sensor cleaning until I got my first DSLR, a
Nikon D70. I learned very quickly.


Also, I believe the evidence that he is either oblivious to the problem, or
just doesn't care is demonstrated by his posting of all those contaminated
photographs to Flickr with no effort to fix anything.

Well, maybe the photos themselves are important (to him) and he can not
go back to repeat them. I have photos like that, with errors, but they
are important to me.

If they were important to him he should have taken care when producing
them. He could certainly have cleaned up the spots on the images with post
processing before publishing them in Flickr.

I wouldn't know how.

Are you reluctant to learn anything?

Certainly not :-)


But I don't go criticizing somebody which posts some far from perfect
photos, for reasons we don't know about. I only try to point out, as he
is not here to defend himself, that there may be reasons.

Maybe he did not intend you to see them, LOL! :-D

Maybe he doesn't know how to clean them, and there are no cleaning
services in Algeria.

If you look at the end of his album, there is no dust:

https://www.flickr.com/photos/marcodileo/6680221601/

If you go to page 20, I can see just one big speckle on the left on some
photos. Maybe by that time he had found out how to clean the sensor or
took the camera to some place.

People take time to learn, after all.


Me, I would not have posted with that defect without an explanation.




Cleaning up unwanted dust spots or other blemishes is a feature of most
photo editing software, even some of the free software.


Sure, but those are huge. Anyway, what that software does is some kind
of interpolation, because the data of those pixels under the dust is
lost forever.




What camera do you shoot?

...and which camera was it that you use?

Oh, a Nikon D3200. What I could afford. I'm not a professional.


If you have photos that are important to you, but have "errors", do
whatever you can to fix those errors in post. That is why editing tools
exist.

You can not correct focus on post.


That is a whole different problem.

It is. But it is the one I might want to correct, I don't have dust.

false.

photoshop and several other tools, such as focus magic can help fix out
of focus images:

I have my doubts, even after seeing the samples. It will be expensive,
out of my bracket.

Maybe he did not see the defect till back home because he did not have a
computer on the trip. That is what happens to me, I did not see the out
of focus defect on some important (to me) photos because it is not
visible in the camera display. I did not see it till days later on the
computer, too late to repeat them.

maybe he belongs to a school of thought that does no postprocessing. I
don't, I consider postprocessing cheating. :-P

Maybe he simply posted the entire repertoire as is, before
postprocessing, and only a few photos were treated somewhere else.

:-P
