Take photos Perspec is great for correcting photos of documents, receipts, whiteboards, facades, or any other planar objects. 2. Open Perspec app 3. Select photos to correct Either use the \"Select Files\" button or simply drag & drop the photos onto the window. Perspec's integrated computer vision algorithms will automatically detect the corners of the document and mark them with circles. If the corners are not detected correctly, you can manually drag the circles or the edges to the correct position. 4. Save the corrected image Either click one of the save buttons or hit Enter to save the corrected image. This will save the image in the same directory as the original photo with -fixed appended to the filename. If you selected multiple photos, they will be opened one after another. Button Description Result Save Saves the image in 24-bit color. Save Gray Saves the image in 8-bit grayscale and normalizes the range of values. Save BW Saves the image in true 1-bit black & white (each pixel is either black or white). Save BW Smooth Saves the image in mostly black & white with some grayscale edge smoothing.
