Extract the green channel, because it has more contrast between the rust and the non-rusted areas. Get a nice texture and saturate it a bit.ī. One 100 % synthetic Paint.NET image, where all presented is in use:Ī. With the magic wand all black were selected, the selection was inverted and in the green layer DEL was pressed. The green got the holes and the white layer is the background that makes the holes well visible. You see the tresholding dialog:Ī solid green and a solid white layer were added. In the left there's the noise, in the middle it's blurred and in the right it's tresholded. The levels tool is used as treshold effect. Then convert it to BW with the levels tool. You can start from maximum strength grey noise, which is blurred. The upper part uses the embossed cloud to add the brightness. The lower part has the cloud with emboss (Effects > Stylize > Emboss) and some contrast boost. Embossing is the effect which creates an illusion of depth. TR's Alpha mapper can help the lack of layer masks. Weird effects result if the Cloud isn't black and white.ģrd party filters such as Recolour Choice and TR's ColorizerHMS can make the BW cloud colored. Here we add the brightness with blending mode ADD:īlack affects nothing and white makes the color washed. If we put the "Cloud" over a solid color layer and use reduced opacity + some blending mode other than normal, we can modulate the underlying color. We have black foreground color, but other colors work, too: With no softness it makes something which resembles worn surfaces. Paint.NET has cloud synthesizer filter like Photoshop or GIMP. The letters are selected by clicking them one by one: See the tool options panel: The Magic Wand is in union mode with 3% tolerance. Now in Grey+noise layer select the grey letters with the magic wand. Insert a new bottom layer and fill it with a solid color. inset to "Grey+noise" layer colorless noise with max intensity and coverage.Select with magic wand the black part with low selection tolerance in the tool options panel, say =1% for sharp result We use the text for making selections in other layers to keep it available in case of errors and other reasons to make multiple selections. We have not vector texts, so we need good contrast. Detoriated text hole in a colored layerĪt first we make a white text on a solid black layer. Paint.NET has still a good set of basic tools and filters, plenty of them as standard and much more as downloads.ġ. For it make spare duplicate layers and intermediate savings. If you make an error, you cannot readjust like in Photoshop, you must go back. It hasnt layer masks, adjustment layers, smart objects, smart filters, layer styles, vector shapes nor vector texts, which in Photoshop make non-destructive work possible. Paint.NET has noise and texture synthesizing filters. The washing effect can be reduced in black areas by moving the posterized BW layer on top: NOTE: The difference between this and the original is obvious only when zoomed in. With reduced opacity(and the black layer removed) the result is: Against solid black the added layers are these: I painted some white, blurred it with gaussian blur, inserted greyscale noise and added another layer with blurred white without noise. It's useful to add a layer which adds some grain (=noise) and washes the colors. Its contrast and brightness is adjusted separately to prevent it to become black in posterization. NOTE: Your image had a large red area which is quite dark. With reduced opacity the BW layer appears as sharp details. I have done them in Paint.NET (= freeware, quite capable photo end bitmap image editor): Increasing the contrast is useful to do before posterization. One possiblity to add the sharpness is to make a black and white copy of the image, posterize it to few greyshades and adjust the contrast with levels or curves tool. Otherwise the texts seem inserted afterwards. They should have also some sharp details. Your problem: Your texts are razor sharp, but the surface textures are not. Obviously you have still not tried to erode text RESTRICTED AREA, which is a hole in the red paint. If that's wanted, washing the colors by painting over is already presented in another answer. Also the knackered black text is quite plausible except its paint is not at all washed out during the years. I see you have found some plausible images of detoriated painted surfaces.
