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.

I was referring to the first half of my own post.

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.
Who is being sarcastic and in what context?

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!

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 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.

If you don't believe me, ask John Riley. Few people on the planet have bought more lenses on Ebay than JR. Choose your seller with care, and the chance of a dud buy is almost infinitessimally low.

It seems, though, that you may not have noticed that my camera is now out of warranty.
Worth a try?

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.
