User ManualIntroductionTopaz DeJPEGJPEG ArtifactsWhat Are JPEG Compression Artifacts?JPEG compression artifacts are random and unwantedimage distortions that appear in JPEG images. Most often,JPEG artifacts appear in photos as blocks, dots andfringes. These artifacts are also referred to as: Checkerboarding,and mosquito noise.To see if your images are being affected by JPEG artifactsbecause of compression, zoom in on the imageand look for areas with checkerboard patterns, mosquitonoise, fuzziness, reduced detail, reduced clarityor uneven color.What Causes JPEG Compression Artifacts?JPEG compression artifacts are caused by the compressionthat occurs when you save an image in the jpegformat. JPEG images can be saved at different levels ofcompression and quality. Using a higher compressionproduces a lower-quality image and a smaller imagesize. Using a lower compression produces a higherqualityimage and a larger file size.Benefits and Consequences of the JPEG FormatUsing the JPEG image format is popular because it reducesfile sizes and allows for increased storage. Mostweb images are JPEGs for this very reason. Howeverusing the JPEG format also comes with unwanted andtypically irreversible side effects. The JPEG format is alossy form of compression, and as a result, image qualityis lost and artifacts are introduced. Rhe quality thatis lost from compression cannot be restored andwill continue to diminish in quality every time you editand save the image in the JPEG format.Why can’t I use a Noise Reduction Program to RemoveJPEG Compression Artifacts?Noise reduction algorithms are not effective at removingJPEG artifacts caused by lossy compression methodsbecause images noise is not the same as compressionartifacts. Programs specialized in JPEG artifactelimination can easily target artifacts, successfullyremove them and drastically improve your image withprecision.For more information and to see examples visit:www.topazlabs.com/dejpeg8

User ManualSettings & ParametersTopaz DeJPEGParametersTopaz DeJPEG has two settings tabs and a total of 10parameters plus 3 display modes to help you achieveoptimal image results.MainThe Exposure tab includes the basic and most essentialartifact removal tools. These tools are the main onesthat you will use, and they will resolve most of yourjpeg artifact issues.25DeJPEG Usage Tips:For most users, “Reduce Artifacts” is the only feature youwill need to use when editing images that have minor JPEGartifact issues.Be sure not to overuse the “Reduce Artifacts” slider or thismay cause your image to lose edge sharpness.More advanced users, or images suffering from seriousartifacts, may require additional use the of the sliders inthe Advanced tab.Reduce ArtifactsRemoves the artifacts in your image. A higher value removesmore JPEG artifacts but may also over-soften theimage. A good rule of thumb is to start with a smallervalue and slowly increase this parameter to strike theperfect balance artifact removal and edge integrity.Smooth ColorSmooths out the color in the image. A higher valueprovides a smoother color, but you may loose detail ifyou set this value too high.

User ManualSettings & ParametersTopaz DeJPEGSharpenSharpens the image’s edges in order to compensate forthe image softening that occurs from the JPEG artifactremoval process. This parameter works in conjunctionwith the Sharpen Radius Parameter.Sharpen RadiusThis changes the edge size of sharpening, which ismeasured in pixels. This value adjusts how large theedges to be sharpened are. Use a larger value for moreblurred areas, and a smaller area for less blurred areas.AdvancedThe Advanced tab offers additional tools that can helpcreate a well-balanced image.Luma NoiseReduces noise in the luminance (black-and-white) channel.Color NoiseReduces noise in the color channels.Color Edge RadiusIncreases the sharpness of the color edge. The parameteris ideal for recovering lost color detail.Edge ThresholdSets the threshold above which the color edge will beenhanced. Use it to change the strength of the edgedefinition.SaturationIncreases saturation and evens out image color to compensatefor color loss due to artifact reduction.26Add GrainAdds monochrome grain to the image in order to makeit look more nature.DeJPEG offers 3 differentColor Viewing Modes thatyou can use to help withartifact removal and imageenhancement while usingTopaz DeJPEG.Enable the “Auto-Brightness” feature to brighten theimage for better viewing of artifacts in dark areas. Auto-Brightness is for previewing only, your image will notstay brightened once you process your adjustments.

In the following steps, we will showyou how to achieve optimal results with your ownphotos, following this model. Let’s get started.1. Open an image file.2. Create a duplicate layer of your image. Right-clickon your image layer in your layers and select “DuplicateLayer”. You can also achieve this by selectingyour image layer and dragging it down to the newlayer icon.35Before Topaz DeJPEGAfter Topaz DeJPEGDon’t forget that you can use the shortcut keys inTopaz DeJPEG 4 to speed up your workflow.

If you want to choose a default preset, scrollthrough the panel on the left side of the screen. Toselect it, just click on it and the sliders will automaticallyadjust to the pre-defined settings and parameters.For this example we will be using the HighlyCompressed JPEG preset.36

User ManualWorkflowTopaz DeJPEGWith a variety of presets you will often find that asingle selection will give you optimal image results.If you are satisfied with the preset adjustments thenyou can click “OK” to process your image and save itback to Photoshop.Incorporating Manual Adjustments:Start in the Main tab. It is a good idea to begin here,starting with the Reduce Artifacts slider and thenprogress to the Sharp Radius slider in order to see theeffects of your adjustments easily.If you would like to make some additional adjustmentsto your enhancement settings then you can doso by adjusting any of the sliders in the two tabs manuallyuntil you achieve your preferred image results.1. You should already be in the “Normal” color mode.Switch to the “Luma” color mode. This is the blackand-whitemode which enables you to see the imagewithout color artifacts.37

User ManualWorkflowTopaz DeJPEG2. In “Luma” mode, go to the “Reduce Artifacts”sliderunder the Main tab and adjust it to a level where youare satisfied. Since a higher value may soften theedges, it’s a good idea to start with a small value andslowly increase it. That way, you can be sure that yousufficiently remove artifacts while preserving edgeintegrity.4. Switch to the “Color” mode. If you find that thecolor in your image is a little uneven, adjust the“Smooth Color” slider to clean these areas.The Main tab will generally be all you need to usewhen making adjustments. However if you feel yourimage needs additional work then continue on to theAdvanced tab.5. If you find that there is noise in your image, you canreduce it by using the “Luma Noise” and “Color Noise”sliders. First, switch back to “Luma” mode and apply the“Luma Noise” adjustment. Then, return to “Color” andapply the “Color Noise” adjustment until you are satisfied.This will help clear up a noisy image.6. Now, still in “Color” mode, you can improve coloredge detail, by going to “Clr Edge Radius” and raising thevalue of that slider. Use it along with “Edge Threshold”to set the strength of the edge definition.383. Then move to “Sharpen.” If you find that you havelost some edge detail by reducing blockiness, you canmove this slider up to recover it. Use it with “SharpenRadius” to control edge harshness. Higher levels aregood especially for blurred areas.Your image should now be free of JPEG artifacts. Tomodify any additional aspects of the image, proceedwith the next steps.Need to reset your slider values?Simply double-click on the slider name above the slidercontrol to instantly reset the slider value to 0.7. Color can also sometimes be weakened in the artifactreduction process. You can fix this by going to “Saturation”and raising the value of this slider to recover somecolor and balance out the saturation in the image.8. Finally, you can add in some grain to make the finalimage look a little bit more natural with the “Add Grain”slider. This is set at a default value of 0.05.The best way to get great-looking images is to experiment withthe filter until you’re satisfied. Despite the number of sliders andsettings, getting a great result is easier than you might think!
