Image tracing is a technique used in graphic design to convert a raster image (such as a photograph) into a vector image (such as a line drawing). Vector images are made up of paths, which are defined by mathematical equations. This makes them scalable and resolution-independent, meaning that they can be enlarged or reduced without losing quality. Raster images, on the other hand, are made up of pixels, which are fixed in size. This means that when they are enlarged, they can become pixelated and lose quality.
There are a number of different ways to image trace in Photoshop. The most common method is to use the Image Trace panel. The Image Trace panel provides a number of presets that you can use to quickly and easily create vector images from your raster images. You can also use the Image Trace panel to manually trace your images, giving you more control over the final result. To manually image trace in Photoshop, you will need to use the Pen tool to create paths around the edges of the objects in your image. You can then use the Pathfinder panel to combine the paths into a single vector object. Here is a step-by-step guide on how to image trace in Photoshop:
1. Open your raster image in Photoshop.
2. Go to the Window menu and select Image Trace.
3. In the Image Trace panel, select a preset from the Preset drop-down menu.
4. Click the Trace button.
5. Photoshop will create a vector image from your raster image.
6. You can now use the Pen tool to manually trace any areas of the image that were not traced correctly by the Image Trace panel.
7. Use the Pathfinder panel to combine the paths into a single vector object.
8. Save your vector image in a format such as EPS, SVG, or PDF.
Preparing Your Artwork
Before you begin image tracing in Photoshop, it’s important to prepare your artwork to ensure a successful and efficient process. Here’s a detailed guide to help you get started:
1. Choose the Right Image Format
The image format you choose can significantly impact the quality of your image trace. Ideally, you should work with an image saved in a lossless format, such as PNG, TIFF, or PSD, which preserves the image’s original data without any compression artifacts. Avoid using JPEG images, as they are compressed using a lossy algorithm that can introduce unwanted noise and artifacts.
| Format | Advantages | Disadvantages |
|---|---|---|
| PNG | Lossless compression, high quality | Larger file size compared to JPEG |
| TIFF | Lossless compression, supports layers and transparency | Large file size |
| PSD | Lossless compression, supports layers, masks, and other Photoshop features | Proprietary format, may not be compatible with other software |
| JPEG | Lossy compression, smaller file size | May introduce artifacts and noise, not suitable for high-quality image tracing |
If your image is not already in a lossless format, you can convert it using Photoshop’s “Save As” dialog box (File > Save As) by selecting the desired format from the “Format” drop-down menu.
Convert to Black and White
To convert your photo to black and white, there are several methods you can use in Photoshop. Here are two common techniques:
Method 1: Using the Desaturate Adjustment Layer
1. Create a new adjustment layer by clicking the “Create new adjustment layer” icon in the Layers panel and selecting “Hue/Saturation.”
2. In the Hue/Saturation adjustment panel, click the “Desaturate” checkbox to remove all color from the image.
3. Adjust the sliders for Brightness and Contrast to balance the tonal range of your black and white image.
Method 2: Using the Black & White Adjustment Layer
1. Create a new adjustment layer and select “Black & White.”
2. In the Black & White adjustment panel, you can fine-tune the conversion by adjusting the sliders for each color channel.
3. Use the “Toning” section to add a tint or sepia effect to the black and white image.
| Adjustment Layer | Method |
|---|---|
| Desaturate | Quick and easy method that removes all color. |
| Black & White | Provides more control over the conversion with individual color channel adjustments and toning options. |
Adjusting Image Settings
Fine-tuning your image before performing image tracing can significantly improve the tracing results. Here are the key settings to consider:
Contrast and Brightness
Adjusting the contrast enhances the distinction between light and dark areas in your image. Increasing the contrast can make edges more defined, making them easier to trace. Conversely, decreasing the contrast can soften the edges, resulting in a smoother trace.
Brightness affects the overall lightness or darkness of the image. Balancing the brightness can help ensure that the edges are sufficiently visible for tracing while not saturating the colors too much.
Color Mode
The color mode of your image has a direct impact on the accuracy of the image trace. Converting to grayscale or black and white can simplify the image, making it easier for Photoshop to distinguish between edges. However, if you want to retain the colors in your traced image, ensure that you’re working in a color mode that supports it, such as RGB or CMYK.
Table: Recommended Color Modes for Different Tracing Purposes
| Purpose | Recommended Color Mode |
|---|---|
| Sharp, detailed traces | Grayscale or Black and White |
| Colorful, accurate traces | RGB or CMYK |
Threshold Levels
The threshold level determines which pixels in your image are converted to vector paths. A higher threshold value excludes more pixels, resulting in a less detailed trace, but with smoother edges. Conversely, a lower threshold value includes more pixels, creating a more detailed trace, but with more jagged edges.
Finding the optimal threshold level requires experimentation based on the complexity of your image. Start with a medium threshold level and adjust it gradually until you find a balance between detail and smoothness.
Selecting Tracing Options
Once you’ve selected your image and the Image Trace window is open, you’ll need to choose the tracing options that best suit your needs. There are four main sections to the tracing options:
Mode
The mode option determines how the image is traced. The three modes are:
- Black and White: This mode creates a two-color image, with the traced lines in black and the background in white.
- Grayscale: This mode creates a grayscale image, with the traced lines in varying shades of gray.
- Color: This mode creates a color image, with the traced lines in the colors of the original image.
Palette
The palette option allows you to choose the colors used for the traced lines. You can select a pre-made palette from the drop-down menu, or you can create your own custom palette by clicking on the “Edit” button.
Threshold
The threshold option determines how closely the traced lines follow the original image. A higher threshold will result in fewer traced lines, while a lower threshold will result in more traced lines.
Paths to Document
The paths to document option determines whether or not the traced lines are saved as paths in the Photoshop document. If this option is selected, the traced lines will be saved as paths that can be edited and manipulated.
Editing Your Traced Image
Once you have traced your image, you can edit it in a variety of ways to achieve the desired look. Here are some tips:
Adjust the Trace Settings
You can adjust the trace settings to fine-tune the appearance of your traced image. To do this, click on the “Image Trace” panel and adjust the settings in the “Advanced” tab. You can experiment with different settings to see how they affect the traced image.
Adjusting the Threshold
The threshold setting controls how much detail is included in the traced image. A higher threshold will result in a more detailed image, while a lower threshold will result in a simpler image. Experiment with different threshold settings to find the one that produces the desired result.
Refine the Vector Paths
You can refine the vector paths of the traced image using the “Pen Tool” or the “Direct Selection Tool”. To do this, select the path you want to edit and use the tools to adjust its shape.
Using the Pen Tool
The “Pen Tool” allows you to create new paths or edit existing paths. To create a new path, click on the image where you want to start drawing. To edit an existing path, select the path and then click on the points you want to adjust.

Troubleshooting Common Issues
Image Trace Not Working Properly
Ensure that the image is in high resolution and has good contrast. Poor image quality can lead to incorrect tracing results.
Complex Images Not Tracing Correctly
Avoid tracing highly intricate images, as they may result in complex or messy vector paths. Consider simplifying the image first.
Fine Details Lost
Adjust the Threshold slider to lower the tolerance for tracing. This will preserve more fine details but may increase the number of vector paths.
Jagged Edges
Enable the Corner Options checkbox and adjust the Corner Threshold and Corner Detail sliders to smooth out jagged edges and curves.
Incorrect Color Trace
Select the desired color quantization method in the Preferences > Image Trace panel. Experiment with different settings to achieve optimal color accuracy.
Overlapping Vector Paths
Check the “Ignore White” checkbox to exclude white areas from tracing. Adjust the Invert checkbox to exclude black areas instead.
Missing Details
Increase the Tolerance slider to include more details in the tracing. Alternatively, adjust the Paths > Simplify menu to reduce the number of vector paths while preserving key details.
Slow Processing
Consider optimizing the image before tracing by reducing its size, removing unnecessary elements, and applying noise reduction filters. This can significantly improve processing speed.
Enhancing Traced Images
Once you’ve traced your images, there are a few additional steps you can take to enhance their quality and versatility.

Advanced Image Tracing Tips
**1. Adjust Threshold Settings:**
Fine-tune the threshold levels to optimize the level of detail captured in the resulting vector image. Higher values preserve more detail, while lower values simplify the image.
**2. Use Color Reduction:**
Reduce the number of colors in the original image to simplify the tracing process. This reduces the complexity and improves the accuracy of the vector output.
**3. Apply Gaussian Blur:**
Apply a mild Gaussian blur to the image before tracing to soften edges and remove noise. This facilitates tracing by reducing the number of sharp angles and jagged lines.
**4. Trace in Stages:**
Divide the image into smaller sections and trace them individually. This allows for greater control over the tracing process and ensures a higher level of accuracy.
**5. Use Different Trace Modes:**
Experiment with different trace modes, such as Black and White, Color, or Multiple Colors, to achieve specific effects. Black and White produces a simplified monochrome image, while Color preserves the original colors.
**6. Adjust Path Settings:**
Customize the path settings to control the smoothness, detail, and fidelity of the vector image. Increase or decrease the “Tolerance” and “Curve Fit” values to optimize the trace quality.
**7. Optimize Paths:**
Once the tracing is complete, use the “Optimize” command (under the Options menu) to reduce the number of anchor points in the paths. This simplifies the vector image and improves performance.
**8. Use the Vector Pen Tool:**
In cases where the automatic tracing tool falls short, manually refine the paths using the Vector Pen Tool. This provides precise control over the shape and contour of the vector image.
**9. Explore Trace Presets:**
Take advantage of the built-in trace presets in Photoshop. These presets offer a range of predefined parameter combinations designed for different image types and tracing scenarios.
**10. Experiment with Tracing Options:**
