Interesting scan expereince today

If you lost the greys it is most likely a calibration problem.
What you should ask your scanner place is how is the scanner calibrated? Also, How often is it calibrated? Is the computer monitor calibrated? How often is it calibrated? Then if that setip is connected to a printer the same questions should be asked.
Scanners have to be calibrated daily for high end work and often will have different curved depending on the media being scanned.
Some info on calibration is here http://www.silverfast.com/highlights/printer-calibration/en.htmlSome media is problematic with scanning and some colors are out of gamut for scanning/reproduction.

Outside in the shade on a sunny day you have the perfect light for repro work.
If you want a corresponding indoor light obtain a flourescent light with a color temp of 5000k or D50. That's the temp bulb used to match colors and simulates outdoor light.

@smceccarelli Thanks! I usually use my cell phone by the window and sometimes outside. I can see how working in the shade would help. I don't have a camera other than my phone.

@withlinesofink My scanner is a HPG4050 ,when i scan it seems to be showing the grain of the paper/canvas and every single line mistake rather than the whole picture,when I use markers every blotch shows and the colours are muted ,when I use metallics paints they look dirty and biege instead of gold and sparkly.

@dottyp Ah yes. A high quality scanner will pick up on the paper texture and all of the little mistakes. You can always tweak the white balance a bit to blow out some of the smudges and erased lines, or amp up the saturation. I personally do all of that clean-up in Photoshop after scanning.
Transparent mediums like markers and watercolor can sometimes be difficult with the harsh light of a scan because every overlap and difference in layer depth is emphasized as the light blows through it. I always recommend those be photographed instead.
Metallic paints will NEVER scan metallic. In fact, it's difficult to even photograph them in a nice way. They're one of the mediums that really just needs to be seen in person, but you can play with lighting in a photograph to get a bit of that sparkle to show up.

@withlinesofink Oh I see! it was meant to be a really good scanner when I bought it.(of course it is probably outdated now) I will try to adjust my white balance.This is very interesting information as I always thought my shading and lines were ok until I scanned them.Thanks this really explains a lot.

@withlinesofink Really interesting. I used watercolor so that could be a reason for the crazy scans too.

Sorry if I'm high-jacking, but are you scanning in TIFF or JPG? If you are scanning in JPG, scanning in TIFF might help.

@tessw I have tried jpeg and tiff it does not seem to make any difference I think it is just hard to scan work done with markers .Thanks for the help anyway.

A tif file is a lossless which retains all the file information everytime you open and close the file. The files are larger with tif.
A JPG file is a lossy format which removes information from the file everytime it is saved and resaved. It is a smaller file format than tif.
A PNG is a lossless format which retains the quality and compresses the file. If you want tp use this for production you should check with your printer as some RIPs can have problems rasterizing this format.
