The 3 most popular photo effects
The cross development
Cross development, also known as cross processing, is a technique from analog photography that was particularly popular in the 1980s. The goal was bright or washed-out colors combined with hard or blurry contrasts. This effect has been achieved, for example, by reversing a color negative film.
In digital photography, this effect can be achieved either with special camera filters or with effect programs that are available in some digital cameras. But you can also simulate cross processing with image processing programs such as Adobe Photoshop or GIMP. The image effect can be achieved, for example, by shifting the color channels in the gradation curves.
In Photoshop To do this, open “Image”, “Corrections” and “Gradation Curves” in the main menu bar. In the dialog window that opens, activate the checkbox in front of "Preview", select the value "Red" from the drop-down list behind "Channel" and move the line in the gradation curve window into a slightly curved shape.
Observe the color change in your picture. Then repeat this step with the “Green” and “Blue” channels. If you are satisfied with the result, close the window by clicking on "OK" and adjust the brightness and contrast if necessary.In GIMP 2.8 there is this effect for free. To do this, call up “FX-Foundry”, “Photo”, “Effects” and “Cross processing effect…” in the main menu. In the dialog window that opens, specify the opaque color in the color selection field next to "Overcast color:" and then start the process by clicking on "OK".
The sepia effect
Sepia is the yellowish-brown color that very old photographs often have. These photos were originally taken in black and white, but due to the irradiation of UV light, the proportion of black color has faded to a brown tone over the decades and the part of the image that was previously white has yellowed. You can also observe this photo effect if you print out your photos with poor printer ink and expose them to daylight for a few weeks. However, you can also deliberately add a sepia effect to your pictures.
In Photoshop To do this, open "Image", "Corrections", "Hue / Saturation ..." in the main menu and select "Sepia" in the drop-down list in the drop-down list after "Default:". Then activate the checkbox in front of "Color" and click on "OK". If you want to see the photo effect before it is applied, check the checkbox in front of "Preview".
Another possibility to create the sepia effect in Photoshop is the detour via "Image", "Corrections" and "Black and White". In the dialog window that opens, activate the checkbox in front of "Color Toning" and then click the color selection button.
A window opens again in which you can select a suitable color, for example beige or ocher, by clicking on the color selection field. Confirm your selection by clicking on "OK" and, if necessary, set the hue even more precisely using the slider under "Saturation". This method has the advantage that you can determine the shade yourself.
If you are using the sepia effect GIMP want to imitate, the easiest way to do this is to call up "Colors" and "Colorize" in the main menu. In the dialog box that opens, use the sliders under "Select color" to set the hue, for example, to "17", the saturation to "62" and the brightness to "43".
Split toning is also an effect from the days of black and white films. To create this effect, the light parts of the image are colored in one color and the dark parts in another. Split toning gives color images a special look, especially if you choose colors that are opposite in the color wheel, for example blue and yellow or red and green.
The easiest way is to use this effect GIMP around. Open "Filter", "Colors" and "Split Tone with ED". In the “Script-Fu: Split Tone with ED” dialog box, select the color for the lights from the color field behind “Highlight color” and the color for the shadows from the color field behind “Shadows color”.
Use the sliders next to "Highlight opacity" and "Shadow opacity" to set the opacity of the highlight and shadow colors. The further you move the slider to the left, the more uncovered the color. GIMP first automatically creates a layer with a black and white copy from your image and then the layers for the "shadows" and the "highlights".
A very popular effect is the Colorkey effect, in which important elements of a black and white picture are highlighted in color, such as a red umbrella. To create the Colorkey effect, you'll work in GIMP similar to in Photoshop.
Open your image and make a copy of the original layer (background layer in Photoshop). Mark the area of the image that should be colored, for example with the quick selection tool or the magic wand. Then activate the eraser tool and erase the marked area.
The best way to do this is to deactivate the background layer by clicking the eye icon until you have finished erasing. Select the copy of the background layer in the layer palette and click on "Image", "Corrections" and "Black and White" in the main menu bar. You can use the sliders under the color tones to change the brightness values of the individual colors in the subsequent black-and-white conversion.
When you have made all the settings, close the dialog by clicking on "OK" and save your finished image.
