Using Gertrudis Pro and Adobe Photoshop Masks to create magical worlds with your pictures.

The intention of this tutorial is to combine two powerful tools such as Gertrudis Pro and Adobe Photoshop to take advantage of to the maximum realism of a photograph and enrich it with the natural sensitivity that Gertrudis Pro gives to any image.

First thing you’ll need is a neutral background photograph such as a sky, plain color, etc. This is not an essential requirement nevertheless it will help the final result to be far better.

  1. Open your picture in Adobe Photoshop
  2. Create a New empty layer (choose “New Layer” from the Layers palette menu.)
  3. You must create a mask to trim the background. This will have a double function:
    1. Defining the work area for Gertrudis knowing that it will be visible in Adobe Photoshop.
    2. Cutting the original image from Gertrudis Graphics to make only visible the chosen zones of the image (in this example example, the sky).
      Tutorial 01 Image 1

    Use the Magic Wand tool to select the approximated area of the sky you want to work with. You can use as much selection tools as you wish to make a more precise selection. Once you have finished, click the Add Layer Mask button. This will define the work area in an empty transparent Layer.

  4. Place your cursor on the Layer Mask Thumbnail and click with the left button and ALT key. This will let you see the mask in black and white. Select the entire image (Ctrl+A) and copy it, pressing Ctrl+C in that layer.

  5. Now it is the turn of Gertrudis Pro! Open the program and select New From Clipboard (Ctrl+Alt+N). Leave the software’s presets, and open the image.
  6. Use the Autosketch Tool and a large size brush to reconstruct the image in Gertrudis using the technique that suites you better. Scratch Style is used in the example. You must define the black and white zones very carefully. In the image bellow Gertrudis is working on the white zone only, since the black zone will not be visible in Photoshop when the mask is finally applied.

  7. In order to generate an interesting effect choose the Freehand tool. Apply Fixed color option in the color palette and work with black and white values. This is not essential but it will be useful for a better visual orientation. The effect will be attractive mainly when playing with ink’s transparency. Soon, when taking the image to Photoshop, you will use a translucent blending to produce diverse effects.

    • Use the Freehand Tool, directing the brush with the software help.
    • Use fixed color mode.
    • Adapt the ink transparency to create different color values (neither white total nor black total).
    • Play and work with diverse brushes.
  8. Alternate different brushes and thicknesses and work on the image until you reach a pleasing result.

  9. Save your image selecting Save At Different Size option. Type width and height values in pixels of your original picture in the dialog box.
  10. Go back to Photoshop and open the new image you created at Gertrudis.
  11. Click on Create New Layer in your original file. Place the image you generated on Gertrudis in this layer. Select the window corresponding to this image in Photoshop, click Ctrl+A to select it, and Ctrl+C to copy it to the Clipboard. Return to the other file, and in the new layer, press Ctrl+V to paste the image from Gertrudis Graphics there.

  12. Now you see the work you did in Gertrudis in the upper layer, but blocking the image that was underneath. Drag the mask icon of the layer below to the Gertrudis’ image layer to apply this mask to the image.

  13. Well… the effect does not seem very pretty, right? This is the final touch: place your cursor on the layer that is applying the mask on the image of Gertrudis, select it, click it with your left button. Select the Overlay blending mode.

I hope you have been able to accomplish this tutorial goal without any problems. You can try different blending options in the Layers palette on Adobe Photoshop and play with the layer’s opacity to obtain different effects. The key is to start from a good image, to have a good selection mask and to be creative with Gertrudis Pro to enrich the photograph with textures and outlines.

From Coarse to Fine Details, how to create your drawings faster and smaller

Filed under: Tips & Techniques,Tutorials — enieloud @ 6:14 pm

Often I’ve been asked for the size of the Gertrudis Projects Files.
The size of the project is proportional to the number of strokes. Thus is, as more strokes has the project, the greater size it has.
One way to reduce the size of the project file is by first filling the entire image with large brush strokes. And then add details only in the areas that need it:

Fill the entire image with a brush at its maximum width and length:

Coarse settings

The two following steps consist in reducing the width and length of the stroke and apply it only in the areas where more detail are needed:

Medium settings
Step 2

Now reduce more:

Minimum settings
Step 3

With this technique you will get not only smaller files. Also you will be able to create your drawings more quicker.
