If you want to edit your photo further, you need to consider the quality and flexibility of your image. The quality is determined by the pixel density and color depth of your image, and the flexibility is determined by the file format and layer structure of your image. A higher quality and flexibility means a better editing experience, but also a larger file size. A common quality and flexibility for editing is 300 ppi and 16-bit color depth in a PSD or TIFF file format with layers preserved. To crop and resize your photo for editing, you can use the same steps as for print or web, but with different values. First, select the crop tool and choose a custom aspect ratio from the options bar, such as 3 x 2 or 5 x 4. Then, drag the crop box over your image and adjust it as needed. Next, open the image size dialog box and enter the desired pixel dimension and resolution. Make sure to check the Constrain Proportions and Resample Image options. Click OK to apply the changes. Then, go to Image > Mode and choose 16 Bits/Channel. Finally, go to File > Save As and choose PSD or TIFF as the file format and check the Layers option.
