Leaning images have plagued photographers for years. The camera can be tilted very easily if the eye is not positioned correctly relative to the viewfinder, the shutter is depressed too forcibly and the camera tilted during the exposure and so on.

A tripod is no guarantee of straight images, depending on the various angles in the shot compared to the viewpoint. Buildings usually cause lots of problems.

Before blaming a camera I think some careful testing with suitable test targets would be a good idea.

I've done a fair bit of this sort of work and once it's set up it's not too much of a chore. Basically, the magazine page needs to be flat on a level surface and the camera back parallel to it. I achieve this by placing the lenshood flat against the page and then raising the tripod column so it stays straight. Then check the viewfinder carefully for precise alignment.

A 50mm macro lens is very useful in that straight edges remain straight and the focusing distance is not too great.

Lighting is usually by one very large window, but 2 lights at 45 degrees works well.

Focusing is manual and aperture at an optimum f8 or so.

If the paper is white, then in Photoshop the white point can be set in Levels with a very high degree of consistency resulting.

Careful and consistent working should deliver excellent results.

Thanks, you may well be right, but the point is made that it wasn't clear. This would probably have needed a quote to make it absolutely clear, and on forums it's a constant challenge not to be misunderstood.

I don't believe in hauling people up for judgement for some spelling and grammatical errors, but it is indeed helpful if some care is taken.

Personally, I write e-mails with proper structure, more like a letter, but that's just my preference.

Sarcasm is another one.
You could mean many things by saying this and I wonder what you actually did mean?

Who is being sarcastic and in what context?

Language is a powerful tool, but to make sure what we say is properly understood it needs to be clear and concise.

As we cannot see the expression of the writer it is even more important that the meaning is unambiguous. To assist with this, we have Smilies!

First load and unload the camera in total darkness. If you don't, light will pipe down the film and fog your images.

400 ASA (ISO) and a red filter will give excellent results, but bracket as the amount of IR light around will vary and there is no way of measuring it.

The 400 ASA setting assumes you are using a TTL meter. A sparate meter will have to be set at 50 ASA to compensate for the red filter.

An orange filter is not strong enough. Red will give the effect you probably seek. The opaque R72 IR filter gives the ultimate result.

If you are making a record shot and you remove things, add things, etc., then there is a potential for it becoming dishonest. Hence troubled times recently for several press photographers who went too far.

If you are creating an image and want it to look a particular way, want to clean it up, remove cables and cars, etc., then it is an artistic decision and anything goes as there is no misrepresentation.

This applies as much to film as digital. Manipulation has always been with us. It all depends on the purpose and intent and whether or not there is an attempt to mislead.

Adjusting contrast and brightness levels and cropping is a very minor thing and is certainly not cheating at all.

It seems, though, that you may not have noticed that my camera is now out of warranty.
Even if out of warranty, sometimes warranty repairs can be achieved. It depends what is wrong and whether you can successfully argue the point.

Worth a try?
