How To Clean A Scanned Image In Photoshop
Traditional sketches are often appreciated more than digital ones. They seem more lively, more "real", and they accept some kind of "soul". However, if you want to present your pencil fine art to a wider audience using the same medium equally digital art—the Net—yous stumble upon one great problem. Any tool y'all use to convert traditional fine art into digital class will have some influence (usually negative) on its quality.
Adobe Photoshop comes to your assistance! If you think that doing annihilation to a scan/photo is cheating, allow me reassure you—whether you lot desire it or not, the conversion itself changes your original picture.

Let's see how!
Digitize Your Traditional Art
I've created my movie using three tutorials:
- How to Draw Animals: Horses, Their Beefcake and Poses—horse anatomy
- Taking Flight: A Beginner's Guide Into Drawing Wings—fly anatomy
- Create a Flight Blitheness From Scratch in Adobe Photoshop—wing poses
A scanner is the all-time tool yous can utilise here. It will give you "nothing perspective", which takes away at least one problem. However, if y'all don't have 1, use a camera. The bigger the resolution, the easier it'll be to achieve a sharp picture. Both means will give yous a digital file with the content looking nothing like your sketch.
1. How to Fix the Perspective
The bigger the picture show, the harder it is to take a moving picture of it without any lens distortion. Let'southward encounter how to fix fifty-fifty the well-nigh extreme case of it.
Step 1
Place your file into Photoshop. Use the Crop Tool (C), concord Alt and Shift, and drag the borders away a fleck to make the canvass bigger. This mode we'll get more space for the transformations without scaling the picture down.
Step ii
Right click the layer and Convert to Smart Object. Information technology'll let you transform the image multiple times without losing quality. Go to Filter > Lens Correction and switch to theCustom tab.
Here you tin play with the Transform sliders to remove the baloney caused by the camera.
Step 3
The previous method has its flaws, and then nosotros need to add together ane more correction. In my case, the picture turned out likewise "squished" vertically. If that'south also your case, right click the layer, Rasterize it, and and then use the Free Transform Tool (Control-T) to stretch it to the proper proportions.
two. How to Remove the Colors
In many cases your black-and-white sketch will exist turned into a mass of random colors, usually because of incorrect white balance. Let'south fix it with one unproblematic step.
Open theWindow > Adjustments panel. Select Blackness & White.
Information technology's done!
3. How to Remove the Messy Background
Smudges, dirt, uneven lighting—the background of your sketch is something you'd gladly say goodbye to. Permit's do information technology!
Stride ane
Add the Layer Mask to the sketch. Make certain your groundwork layer is white, and if not, add it.
Pace ii
Click the white rectangle next to your sketch'south thumbnail. Employ the Soft Round brush to paint roughly the area effectually the character. Remember: black removes, white brings back.
Step 3
Brand the stroke smaller and work precisely on the edges, switching between blackness and white to get the correct event. The background is gone!
iv. How to Prepare the Dissimilarity
Contrast is ordinarily the one and only thing an creative person changes earlier posting a scanned artwork. However, it'due south a far more complicated issue than it seems, and playing with the Dissimilarity slider only may bring more impairment than good. I'll show yous how to manage it properly.
Step 1
Add the Levels adjustment.
Pace 2
This panel shows you the histogram—a distribution of blacks and whites in the moving picture. A perfect histogram looks like a mountain with gentle slopes, but "perfect" doesn't mean the most desirable. The shorter (horizontally) the histogram, the college the contrast. Drag the right slider to the left to turn light grays into white, and the left slider to the right to brand night grays blackness.
There'due south a trap hither waiting for y'all. It may be very tempting to requite rich blacks to your image, but have a look at your traditional sketch. Does it take rich, hard-edged blacks? If non, changing the histogram to get them volition deprive the motion picture of subtle changes of grays. Recall: you want to make the digital sketch await equally skilful as the original—not "meliorate"!
Footstep three
Sometimes, considering of uneven lighting or smudges, some parts of the motion-picture show are darker than the residuum. We need to pick them and change their histogram individually.
Use the Quick Mask Tool (Q) and paint over the area yous want to change.
Press Q one time once more to go dorsum into normal mode and capsize (Control-Shift-I) the selection. Then add the Levels aligning once again—it volition be applied to the option only. Play with the sliders until the chemical element matches the contrast of the rest.
You can apply the same contrast to other parts just by clicking the mask (the rectangle adjacent to the layer's thumbnail) and painting with white over them.
Footstep iv
The problem with the Levels editor is that information technology changes the shades evenly. At that place'southward a big hazard your scanner/camera lost the finest dark shades, and they're very important for the last "experience" of the motion-picture show. You lot can't bring them back with the histogram, but in that location's some other tool—the Curves editor.
This editor is a very powerful i. In fact, yous could accommodate the Levels hither! Let'south meet what it is virtually.
By default, the lower left corner represents the darkest areas of the pic, and the upper right corner represents the brightest ones. By calculation a bespeak on the line and dragging information technology downward y'all brand the expanse it represents darker; by dragging it up, you make it brighter.
If yous want to make the fine dark details darker, add together a indicate near the "black" terminate and drag it down. The line is actually a curve, so you'll need to straighten (balance) information technology with other points. Feel complimentary to play with it to become the event you want!
If you do it properly, only the finest details will get darker—non all the grays.
5. How to Crop the Picture show
This is the most intuitive role, simply let's talk near it anyway.
When drawing traditionally, you are forced to work on the dimensions of the sheet of newspaper. Digitally, you are gratis to use whatsoever. When using the Ingather Tool (C), pay attention to the "rule of thirds" filigree and brand it work for you lot.
six. How to Give It a Traditional Feel
There's i attribute of traditional-digital sketches that's mostly ignored. Newspaper has a texture—that'south why your strokes aren't smooth lines, they're always a bit ragged. Your digital background, on the other mitt, is perfectly smoothen. It doesn't justify the ragged lines, making them look only unclean instead of stylish.
Photoshop has a solution for this, too! First, right click whatever of the layers and select Flatten Paradigm. Then go to Filter > Filter Gallery. Expand theTexture list and select Texturizer. Apply the Sandstone texture with a subtle Relief and a proper Scaling.
At present the subtle texture in the background optically justifies the textured strokes. It's not only a fancy reminder that you've created it traditionally—information technology's actually a must, if you want to make information technology look as it did before digitalizing!
7. How to Prepare It for View
Last but not least, the huge file you lot've probably got after digitizing the sketch isn't what you're supposed to show to others. At that place'due south actually no need to nowadays all the 1 mm strokes in a grade of twenty px! Y'all don't look at the sketch by sticking your eye to the paper, so don't force others to do it.
The other advantage of scaling the sketch down is that the smaller the picture, the more detailed it looks (considering of small gaps between the lines). Also, if your digital original was a scrap blurry, scaling it down may help may reduce this outcome.
To scale the picture down, just go to Prototype > Epitome Size and type a width that is more appropriate. All the pictures in this tutorial are 600 px broad; 700-800 px wide may be a better option for an artwork (depending on how detailed it is). Too, cull Bilinear for the resample method. Scaling (fifty-fifty downward!) is never completely lossless, but choosing a proper method may preclude you lot from losing too much.
If the picture show is scaled and nonetheless looks a bit blurry, go to Filter > Sharpen > Smart Acuminate. Play with the sliders to get a subtle sharpening. This filter is unremarkably pretty useless when it comes to detailed, colored pieces, but information technology works miracles with pencil sketches!
There is no demand to save the motion picture in the same format as your "digitizer" tool. Go to File > Save for Spider web to choose the all-time settings for your image. Most of the time yous don't demand to care nigh the size—just make sure the quality stays intact!
We're Washed!
You can now proudly nowadays your art online! Mayhap these tricks weren't as simple as sliding the contrast up, simply the result is decidedly more attractive.
