Cropping and Rule of Thirds Rotating Applying adjustment layers and masks Correcting color and saturation Sharpening
Best results will come from desktop/laptop software (e.g. Adobe Photoshop CS/Elements and alternatives to Photoshop), although some mobile apps for Android/iOS are also quite capable. Before you begin, make sure to work on copies of photos and not the originals. You don’t want to accidentally and/or permanently overwrite/lose the original data! Cropping a photo involves removing unwanted (typically outer) parts of an image. It’s quick and simple to do, and the results can turn great photos into professional-looking ones. Consider:
Crop to improve composition/focus: If your subject matter feels small and/or lost within the image, crop so that it fills the frame – more subject, less background. Or you might want to “zoom-in” on a specific part of the subject. Either way, the change of perspective will help to emphasize and create a clearer point of interest to viewers. Crop to remove details: Distracting elements can be wayward shadows, bits of trash, unrelated objects/strangers, excessive backgrounds, unused/empty/uninteresting space, or anything else that intrudes on or doesn’t contribute to the spirit of the photograph. Cropping is an easy fix, especially if such distractions are towards the edges of the image. Crop to change orientation/framing: When taking pictures in the moment, we may forget to hold the camera in a way that complements the subject (i.e. vertically for tall scenes/objects, horizontally for wide scenes/objects). You can apply a horizontal crop to a vertical image or a vertical crop to a horizontal image in order to switch the perspective and create a stronger piece. Crop to change aspect ratio: Cameras can shoot in different aspect ratios, which offer different qualities in terms of what a person sees within the image (e.g. a 4:3 aspect ratio picture is distinct from one set to 5:4 or 1:1). Cropping for aspect ratio can also be crucial when one wants to print photos at a specific size in order to fit a frame.
One of the most common terms heard in photography is the Rule of Thirds, which relates to composition. Think of the Rule of Thirds like superimposing a 3x3 grid (i.e. tic-tac-toe lines) on top of an image – many digital cameras and software editing programs have this as a standard feature. Studies have shown that, when looking at an image, our eyes will naturally gravitate towards the intersection points of the grid. However, many of us commonly take pictures with subjects dead center in the frame. By enabling the Rule of Thirds overlay, you can adjust a crop so that subjects/elements are intentionally positioned along lines and/or at intersection points. For example, in landscape photography, you might want to crop an image so that the horizon or foreground is set along one of the horizontal lines. For portraits, you might want to place the head or an eye at an intersection point. The same concept also relates to photography – shots may not always align as intended, even when using a tripod. Rotating a photo just enough can set the correct perspective and get rid of any subliminal distractions. Just don’t forget to crop once more (for framing) after rotating. Consider:
Landscapes: Rotate photos so that the horizon is horizontal from end to end (many image editors can overlay a grid of lines to help with accuracy). This presents a cleaner, symmetrical, and more professional look. Make sure you don’t mistake landscape elements (e.g. sloping hills or valleys, mountain ranges) for the horizon (where the sky meets the earth or sea).Portraits: Instances where someone is leaning up against a vertical surface (e.g. wall, doorway, building, tree, pole, etc.), rotate the photo so that the object is vertical. An exception would be if the object is not vertical in real life – simply reference something else in the image for vertical alignment.
But know that photos don’t always have to be rotated so that elements are perfectly aligned vertically or horizontally. Sometimes, you may want to rotate images (and then crop) to give them a creative, unexpected tilt! When you select an adjustment layer, the Adjustments Panel (typically appears underneath the Layers Panel) offers the appropriate controls. Changes are reflected immediately. If you want to see a before/after, merely toggle that adjustment layer’s visibility (eye icon). You can have multiple adjustment layers at the same time, either to compare (e.g. seeing if you prefer black and white vs. sepia tones) and/or combine effects. Each adjustment layer comes with its own layer mask (represented by the white box next to the adjustment layer’s name). The layer mask controls the visibility of selected portions of that adjustment layer – white areas are visible, black is hidden. Let’s say that you have a photo you want to make black and white except for everything that is green. You would select Hue/Saturation when creating an adjustment layer, move the Saturation slider bar all the way to the left (-100), and then use the Brush Tool to brush over the green areas (you can hide/unhide the adjustment layer to peek at the colors you’re looking for). Over-brushed some pixels? Just use the eraser tool to “erase” those black brush marks. The layer mask’s white box will reflect your edits and show what’s visible and not. If you’re done with or don’t like an adjustment layer, just delete it! The original image remains unharmed.
People’s faces and/or skinSomething in the image you know should be bright white (e.g. shirt, clouds)
The temperature of light (e.g. cooler from the bright blue sky, warmer during sunrise/sunset, drab white under fluorescent bulbs, etc.) during shooting can affect skin tones and white elements with a color cast. Thankfully, small tweaks – particularly with the aforementioned adjustment layers – can correct the colors. Many image editing programs (and some apps) offer an Auto Color Correction feature, which generally works well (but not always perfectly). Otherwise, colors can be manually manipulated by adjusting:
Levels (RGB channels and histogram with an option for auto-correct)Hue/saturation (RGBCMY channels)Photo filters (e.g. warming, cooling, etc.), to name a few.
The aforementioned are available as Photoshop CS/Elements adjustment layers, which offer greater control over removing color casts and improving saturation. To maintain balance and photorealism, take care to not over- or under-saturate an image – or at least the colors that should remain more natural. However, you can make adjustments to select areas of an image (like with the aforementioned layer masks) to saturate specific colors for a bit of creative dramatization. Just don’t forget about adjusting brightness, contrast, highlights, and shadows, since those can help with depth and the separation of colors to really make images pop! Many image editing programs and apps offer an Auto Sharpen feature and/or sliders, which allow users to adjust the amount of sharpening applied to the entire photo. There are also sharpening tools (similar to using brushes) that let you manually sharpen only select areas within an image. But for even greater precision and control, you can use the Unsharp Mask (despite how it sounds, it does sharpen) feature in Photoshop CS/Elements: Remember to view images at 100% size on the screen so that sharpening effects are easier to evaluate (the pixels are represented the most accurately). Study areas with more and/or finer bits of detail will help.
