<p>Select the blurring effect to apply to image.</p><p><b>Zoom Blur</b>: blurs the image along radial lines starting from a specified center point. This simulates the blur of a zooming camera.</p><p><b>Radial Blur</b>: blurs the image by rotating the pixels around the specified center point. This simulates the blur of a rotating camera.</p><p><b>Far Blur</b>: blurs the image by using far pixels. This simulates the blur of an unfocalized camera lens.</p><p><b>Motion Blur</b>: blurs the image by moving the pixels horizontally. This simulates the blur of a linear moving camera.</p><p><b>Softener Blur</b>: blurs the image softly in dark tones and hardly in light tones. This gives images a dreamy and glossy soft focus effect. It is ideal for creating romantic portraits, glamour photographs, or giving images a warm and subtle glow.</p><p><b>Shake Blur</b>: blurs the image by shaking randomly the pixels. This simulates the blur of a random moving camera.</p><p><b>Focus Blur</b>: blurs the image corners to reproduce the astigmatism distortion of a lens.</p><p><b>Smart Blur</b>: finds the edges of color in your image and blurs them without muddying the rest of the image.</p><p><b>Frost Glass</b>: blurs the image by randomly disperse light coming through a frosted glass.</p><p><b>Mosaic</b>: divides the photograph into rectangular cells and then recreates it by filling those cells with average pixel value.</p>

<p>Select your constrained aspect ratio for cropping. Aspect Ratio Crop tool uses a relative ratio. That means it is the same if you use centimeters or inches and it does not specify the physical size.</p><p>You can see below a correspondence list of traditional photographic paper sizes and aspect ratio crop:</p><p><b>2:3</b>: 10x15cm, 20x30cm, 30x45cm, 4x6", 8x12", 12x18", 16x24", 20x30"</p><p><b>3:4</b>: 6x8cm, 15x20cm, 18x24cm, 30x40cm, 3.75x5", 4.5x6", 6x8", 7.5x10", 9x12"</p><p><b>4:5</b>: 20x25cm, 40x50cm, 8x10", 16x20"</p><p><b>5:7</b>: 15x21cm, 30x42cm, 5x7"</p><p><b>7:10</b>: 21x30cm, 42x60cm, 3.5x5"</p><p><b>8:5</b>: common widescreen monitor (as 1680x1050)</p><p>The <b>Golden Ratio</b> is 1:1.618. A composition following this rule is considered visually harmonious but can be unadapted to print on standard photographic paper.</p>
