    Retouch your photos: basic cursors to be resolved during development

    We are talking about development for everything related to The first processing of an image, Namely the adjustment of basic settings: exhibition, white balance, colors, contrast, tone, etc.

    For this, photo retouching software all offer you a series of cursors to be adjusted, in the “Image” (Photoshop) or “Development” (Lightroom) tab or “Colors” (GIMP) and “Adjustment” (Photofilter).

    Adjust the scale, temperature and colors:

    The dominant color of your image is directly linked to the ambient lighting of the shooting. Artificial lighting, for example, will give a dominant red-orange and a hot atmosphere.

    The white balance or the color balance make it possible to alleviate a color too present.

    The idea is to restore the colors of your photo a certain neutrality. Using sliders, you can navigate between hot (red, orange) or cold tones (blue, green, purple) and thus adjust the temperature of your photo.

    Take advantage of great promotions on our site !

    The tab Hunting/saturation Also allows you to compensate for a dominant color, with an adjustment palette of cold tones and hot tones.

    Set tone, brightness and contrast:

    Functions colors, Automatic tone and contrast exist in many software, but beware the result is not always the one desired ! It is best to adjust these variables using the corresponding sliders.

    Set it tone of an image amounts to working its bright values. This can go through the adjustment of several cursors including the tone curve, exhibition, brightness and contrasts. Playing with the tones curve and/or modifying the exhibition can make it possible to catch up with a counter-day, an image too light or too dark. The luminosity and contrast adjustment then helps to restore depth to your image.

    To develop your photos, it is therefore a question of combining a set of variables. If you have any doubts, test the sliders in both directions and use the live preview ! If necessary you can always go back (Ctrl Z / Apple Z / History).

    Some ideas ?

    Intensify a nice landscape with a higher contrast to detach the reliefs and a colder tone to bring out the blue from the sky and/or a lake.

    Refine the features of a portrait thanks to a higher contrast and an oriented light.

    Photo retouching: black & white and filters for more style

    After the development of your photo, you can go further by giving it an atmosphere or a certain cachet.

    Convert a photo to black & white

    The passage in black and white of a photo is possible in all photo editing software. You will find this option in the “Image” tab (Photoshop, Gimp) or “Development” (Lightroom).

    The conversion of a black and white photo requires being supplemented by basic settings, some of which mentioned above: adjustment of tone, brightness and contrasts in particular. Temperature, colors and shades tabs will also have an effect on black & white but this remains relative, difficult to control and not very useful.

    Some ideas ?

    Pass an urban photo in black & white, adjust your brightness and intensify your contrast to create a real aesthetic “city scene”.

    Reframe a portrait, convert it into black and white, intensify its contrast and why not the background vagueness (see. lower): emotions will be there.

    You can test many combinations, black & white has always been a full -fledged photographic practice. Well done, it will give an artistic and intense aspect to your shots.

    Apply a filter to your photo

    Software all offers photo filters that allow you to quickly give your picture a tone.

    For example, you can apply a Temperature photo filter to your photo: warming, cooling, sepia or directly linked to a dominant color. A warming filter will support a warm atmosphere, conversely, a cooling filter will intensify a winter cold, a sepia filter for it will give an aged effect, etc.

    Software also offers you a gallery of artistic filters modifying the colors or the texture of your photos (paint, glow, grain, etc.)).

    For the most sharp, you can play with the layers and the merger under Photoshop or Gimp. This allows you for example to give a Studio atmosphere Or a vintage effect with an image in a few steps. For this internet is full of free tutorials, to your keyboards !

    Convert a black & white photo

    Delete a defect in a photo: retouching the red eyes and using the buffer tool

    From redundant to the disappearance of a person, you can touch your photos by playing the magicians.

    Correct red eyes

    For red eyes, no problem, the majority of photo editing software offers you a special correction tool. We find the “Red eye tool” (Photoshop> Toolbar> Direct tones corrector), “Redeyes” (Photofilter> Filter) or “Deletion of red eyes” (Gimp> Filters> Improvements).

    An advice ?

    Erase red eyes is good, to avoid them is better ! In short, the red eyes are due to the reflection of the light of the flash in the eye. To avoid them you can: limit the use of the flash, diffuse the light from the flash by covering it with a diffuser, a piece of fabric or a white paper, or finally keep the flash away from the lens so that it does not come Directly hit the eye by following the objective of the lens (which requires an external flash). By the way, anti -red eyes modes only change the problem without eliminating it.

    Make an element

    Photo retouching software allow you to go further and make annoying elements disappear: a panel, a cloud, a person, etc. For this they offer a tool ” buffer ” -” Duplication buffer “(Photoshop),” Cloning buffer “(GIMP) – which allows you to subtly hide areas of your photo. It gives the possibility of painting part of your image using as a basic palette another part of the latter.

    Concretely, you take the buffer tool, you define a sampling point on the area you want to clone (Alt Clic), then stamp the area you want to hide in several times (simple single clicks). A word of advice: zoom zoom !

    Make an element

    Give depth or movement to your photos: Try blurring games !

    Photo retouching software offers you a whole panel of blurring to transform your photos, it is mainly found under the “Filters” tab.

    The depth of field

    To play with the field depth you can use the function ” diaphragm ” Or ” Fuzz of field depth »(Photoshop> Filter> Attenuation),« Gaussian blur »(Gimp> filter> blur).

    This tool takes the form of an surrounded pin. This is to be positioned in the area you want to clear, the rest becomes blurred. You can adjust the intensity of the blur thanks to the circle surrounding the pin or the effect bar located on the right. If you want to keep other areas of the net image, click on it to make a second pin appear !


    You can create an impression of movement or speed thanks to motion blur, Present function in the majority of photo retouching software.

    You choose the angle according to the direction you want to give to the movement. The distance will rule the intensity of the blur.

    As with all touch -ups, check the preview live to properly dose your effect.
