first off, sorry if this question has been asked before, but I have no idea how to even formulate this question properly.
Anyways, it's regarding this image. Originally it was very dirty in the background (still is if you look at the striped mountains and cottage), and I've tried making it white by playing around a bit with the curve adjustments. Obviously the results weren't as white as I wanted them to be, so I decided to dodge some areas (on the other parts of this picture which I didn't include). Later on I decided to pick up the bucket tool. It works very well, but now I'm having this problem. If you look at the red ground, it's all dotted. However, the bucket tool filled up some of these dots too, making the ground very thin.
Any idea what I can do about this? And also, if you have any better suggestions how I can make the background white (the quicker the method the better!) in case the curve adjustment settings doesn't properly work?
I'm using Photoshop CS6.
Thank you in advance!
Here's a section of a quick edit I tried. I looked at the channels, and copied the red one (as it had the least background noise), and pasted it into a greyscale document. I then used the white point and black point eyedroppers in the curves pallet to remove the grey in the background and somehwhat darken the remaining lines.
Try making a new layer over the backgroun layer or a copy of the background layer, click on new layer icon at the bottom of the layers palette, change the blend mode to color, choose white as your foreground color and paint with white on the empty layer where you want it to be white. This is probably one of many ways of doing it but seemed to be a simple way.
Wait, I'm a bit confused. So make a new layer, and then right-click, blending options. I don't have just a "color" mode, I only have Darker Color, Ligher Color, Color Dodge...
Which one of these should I use?
