OK using photoshop Elements 2 (never needed to upgrade) for some strange reason in the last couple of days when i save for web or save as jpeg and then upload the images to my website the images are oversaturated and slightly darker in the shadows.
When using the save for web i look at the preview on the right and this looks OK but on the left window in the "original" image window this looks over saturated
Why has this just started to happen, i recall this happening to me a few years ago and there was some really simple fix which ive forgot.
Another way to improve your colours is to calibrate your monitor, there are two ways of doing this, by far the best costs money buying such as Colourvisions Spyder or the Pantone huey. There is another way that will give resonable results and this is free. click here
