To reduce a picture using a scale factor of 1/4, you can follow these steps:
1. Open an image editing software such as Adobe Photoshop, GIMP, or Microsoft Paint.
2. Import the picture you want to reduce. Go to File > Open and browse your computer to locate the image file.
3. Check the dimensions or size of the image. This can typically be found under the "Image" or "Properties" menu option in your image editing software.
4. Calculate the new dimensions of the reduced picture based on the scale factor of 1/4. For example, if the original image is 1000 pixels wide and 800 pixels tall, the new dimensions will be 1000/4 = 250 pixels wide and 800/4 = 200 pixels tall.
5. In your image editing software, go to the "Scale" or "Resize" option, which is usually found under the "Edit" or "Image" menu. Enter the new dimensions in pixels, making sure to maintain the aspect ratio, which means the width and height should be adjusted proportionally.
6. Apply the scale or resize operation, and your picture will be reduced by a scale factor of 1/4.
7. Save the reduced image under a new name or in a different location to differentiate it from the original image.
Remember to always work on a copy of the original image and keep the original file untouched. This way, you can revert back to the original size in case you need to.
To reduce a picture using a scale factor of 1/4, you need to follow these steps:
1. Determine the dimensions of the reduced picture: Multiply the original dimensions of the picture by the scale factor (1/4).
For example, if the original picture is 800 pixels wide and 600 pixels tall, the reduced picture would be (800 * 1/4) = 200 pixels wide and (600 * 1/4) = 150 pixels tall.
2. Create a new blank canvas with the determined dimensions for the reduced picture. You can use image editing software like Adobe Photoshop, GIMP, or even online tools.
3. Open the original picture using the image editing software.
4. Select the "Resize" or "Image Size" option from the software's menu. This option may vary slightly depending on the software you're using.
5. In the resize menu, enter the reduced dimensions you determined earlier (e.g., 200 pixels wide and 150 pixels tall).
6. Make sure to choose the appropriate resizing method in the software settings. Generally, it's recommended to use the "Bicubic" or "Bilinear" interpolation method for reducing the size of the picture.
7. Once you have entered the desired dimensions and selected the appropriate resizing method, click the "OK" or "Apply" button to complete the resizing process.
8. Save the reduced picture with a new filename to avoid overwriting the original picture.
Following these steps, your original picture will be reduced using a scale factor of 1/4, resulting in a smaller-sized picture while maintaining the original aspect ratio.
