Increasing Image Size by 64 Times: A Step-by-Step Guide

Introduction

In this tutorial, we will explore a technique to significantly increase the size of an image, up to 64 times, while preserving its details. We will walk You through the process using the GMIC QT plugin, which offers powerful tools for image manipulation. By following these steps and making some customizable adjustments, you'll be able to achieve highly detailed blown-up versions of your favorite photos. So let's get started!

Installing the GMIC QT Plugin

To begin, you will need to install the GMIC QT plugin. You can find the plugin and its installation instructions in the description of this video. Once installed, we can proceed to the next step.

Adding Grain to the Image

In GMIC, go to the degradations menu and select "Add Grain." By default, the preset settings are applied. Change the settings to an opacity of 0.3 and a Scale of 50. This will add a subtle grain effect to the image, enhancing its details.

Scaling Up the Image

Next, go to the Image menu and select "Scale." Increase the size of the image by 200 percent using the cubic interpolation method. You will Notice that the image becomes slightly softer as you enlarge it. This is a common effect when working with larger image sizes.

Enhancing with Wavelet Decompose

Now, Let's Enhance the image using the wavelet decompose tool. Go to the Filters menu and choose "Enhance," then select "Wavelet Decompose." Leave the default settings and Create a layer group. This will produce several scales and a residual image.

Duplicating and Modifying the Scales

At this point, we will focus on the top scale, which contains the most detailed information. Duplicate this scale a couple of times, experimenting with different settings if desired. You should start to notice a sharper image with increased details.

Applying Grain to the Residual

Navigate to the residual layer in the decomposition group. Once again, go to the Filters menu and select "Add Grain" in GMIC QT. Apply the grain with an opacity of 0.2 or adjust the settings to your liking. This step further enhances the details in the residual image.

Merging the Layers

To bring everything together, right-click on the decomposition group and choose "Merge Layer Group." This will combine all the layers and provide a before-and-after comparison. You will see that the image now appears more detailed and sharper.

Increasing the Size 16-Fold

To Continue enlarging the image, go back to GMIT QT and select the "Repair" option. Look for "Upscale DCCI" at the bottom and choose "Two Times." This will double the size of the image in both directions. Adjust the threshold and exponent settings to achieve the desired result. Choose "In Place" to avoid multiple stacked layers.

Final Adjustments with Grain and DCCI

For a 64-fold increase, you can repeat the previous step (increasing size 16-fold) once more. However, this process may take a few minutes to complete. Optional: Apply additional grain using the GMIC QT plugin and adjust the threshold settings accordingly. This will add a final touch to the enlarged image.

Conclusion

By following these steps and experimenting with the settings, you can significantly increase the size of your images while maintaining Detail and sharpness. This technique is particularly effective for portraits, as it enhances the texture and creates a skin-like appearance. Remember to use high-quality images for optimal results. Enjoy exploring the possibilities of image enlargement with this powerful technique!

FAQ:

Q: Can I use this technique with low-quality images? A: This technique works best with high-quality images. Using low-quality images may result in poor outcomes.

Q: Are there any alternatives to the GMIC QT plugin? A: While the GMIC QT plugin is recommended for this technique, there may be alternative software available for image manipulation. However, the steps may vary.

Q: How long does it take to complete the 64-fold increase? A: The final doubling step can take a few minutes to process. It is recommended to use high-quality images and be patient during this step.

Q: Can I apply this technique to other types of images, such as landscapes or objects? A: While this technique is most commonly used for portraits, it can be applied to other types of images as well. Experimenting with different settings may yield interesting results.

Q: Will this technique work with any image editing software? A: The specific steps outlined in this tutorial are based on using the GMIC QT plugin. However, with some adjustments, it may be possible to achieve similar results with other image editing software.

Q: Can I use this technique on mobile devices? A: The GMIC QT plugin may not be available for mobile devices. To apply this technique on a mobile device, you may need to find alternative software with similar features.
