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.

Combine Photoshop and Gertrudis Pro to Create a Masterpiece

Filed under: Gertrudis & Photoshop,Tutorials — enieloud @ 8:52 am

1. The Photograph: In order to achieve a nice picture is better to start from a great photography, this photo was taken by a professional Photographer: Emilio Guerrero

Little baby

2. Open your Image with Gertrudis Pro:

Gertrudis Pro 2.2
You can learn more about this software at:

3. Apply coarse strokes along the image: In this case I selected the style named "Watercolor-Large Size", and applied it along the whole image using the Autosketch Tool. Don’t Panic!, this is not the final result.

Step 2

4. Refine the size of the strokes: and apply the Autosketch Tool only in the areas where more details is needed.

Step 3

5. Refine even more the size of the strokes: and apply the Autosketch Tool in the eyes, mouth and fingers.

Step 4
Gertrudis Pro in Action

6. Copy the result to the Clipboard: Now we are going to switch to Photoshop, but before doing this, copy the resultant image to the clipboard. (Ctrl-C)

7. Now Switch to Photoshop: Create a new RGB image: File | New. You should notice that Photoshop suggest in the image size the same size of the contents of the clipboard. Once created the image, press Ctrl-V in order to paste the contents of the clipboard.

8. Create a Brightness and Contrast adjustment layer:

Use the following settings:
Brightness and Contrast

9. Create a Hue and Saturation adjustment layer: Before doing this, select the background. There is no need to make a very accurate selection, you can use for example the lasso tool, then enter in the quick mask mode (just press “Q”), and make a gaussian blur to the selection mask. Exit from the quick mask mode “Q”. Now you are ready to create the adjustment layer.

Hue and Saturation

The Layers Window should be seen like that:

Use Photoshop to superimpose borders

Filed under: Gertrudis & Photoshop,Tutorials — enieloud @ 6:13 pm

To show details in Gertrudis you have two ways:
1. Use small size brushes in the details
2. You can use another image editing tool, in this case, photoshop to superimpose borders and details.

This tutorial will show you the second technique. However at the end of this tutorial you can see the result using the first technique.

Original Image
Original image - Small

Final Image with borders: Gertrudis Pro + Photoshop
Final image - Small

1. Open the original photo in Gertrudis Pro
Quickly apply the strokes along the whole image using the autosketch tool. Using very large strokes, in this case we selected Oil-Large size
Large brush selection in Gertrudis

Coarse result

2. Select in Gertrudis Pro Oil-Medium size, and apply the autosketch tools only in the borders and others areas of interest like eyes.
Medium Brush size

3. Copy the resultant image to the clipboard (ctrl-c)
4. Paste it on Adobe Photoshop (File | New | Ctrl-V)
5. Open the original photo in Photoshop
6. Let’s remove the noise using the median filter (in a 1600×1200 pixels we selected: Radius=16)
Median Filter

7. Now we are ready extract the most important borders from the image: Go to Filter | Stylize | Find Edges

8. Select all, copy to the clipboard (ctrl-c) and paste the borders as a new layer over the “Gertrudized Image”
9. Select this layer and change the blend mode to “Multiply”
10. The final image is almost done. Is up to you if you want to make some more “postprocessing operations”, in this case we applied some lighting effects and give more saturation to the blood. Go to the beginning of the tutorial to see the final result. Also you can see below how Gertrudis Pro could be used stand alone and show details of the image.

Gertrudis and PaintShop Pro- by Gun Ledger

Filed under: Gertrudis & Photoshop,Tutorials — enieloud @ 5:04 am

I made a landscape from a photo taken in my little village. I chose that because of the sunset.

Here is first the photo:

Landscape photo - Small

and here is my Gertrudis painting of it
Landscape photo - Small

What I have to share is how I work. I always start at the edges with a broad Big Pastel with lowered opacity, then I take the Medium Pastel and go over the central part with it.
Then I shift to Small Oil with very low opacity and begin my detail work. Everything that is near the viewer I make sharper with that tool. It is just some parts here that I work in detail. The edges are important, the edge of the mountain, the edges of the trees at the middle and front. So some small details that I fill in with a little more brightness, the water behind the trees, the sunlit details on the path and some of the grass.
I think it is important to vary the softness, so it is more diffuse in the distance.
Then of course I crop it, because gertrudis make strange things at the edges :-)

I hope you can use this. I can make more if you want. As it is now, I am eager to train.
I already see that I make progress with training. I think it lies in the eyes a lot, eyes for which details should be worked on and which should be more diffuse.

You talk about combining Gertrudis with Photoshop. I have done that on several images, but not Photoshop, I work in PainShopPro.

I give you some links to my Gallery.
Thefirst one:

is a composition with a native american girl that actually is a Poser girl. It is so with me that I don’t like Poser at all. I think they are lifeless dolls, but with Gertrudis they can be more alive and human.
The rest is elements from different images, and all is put together in PSP.

The next one, also a landscape:

Here I have layered several images, Gertrudis is one of them, a slightly distorted
variant of the photo in Painter is another. Put together I thik it fives the landscape
just that cold windy atmosphere that I sought.

In the third one

have layered a Gertrudis painting of the womans face with the original photo, to get that softness I wanted.

The same layering technique have used here:

Hope this can be to some help for the blog. I find gertrudis great to combine with
PaintShopPro or Photoshop.

Last I will show you my latest image, a cat prtrait I am very happy with.

Got this photo from a friend
Landscape photo - Small

I decided to first make a portrait of the face, she, or he, has such beautiful eyes.
I cut out the face, doubled the size in Irfanview, and used a vignett filter.
Then I worked with Gertrudis in the same way as in the first landscape. Big brushes at the edges, then medium, at last small oil for the face details.
Here is the result
Cat photo - Small

I think it turned out very well.

Then, just for fun, I made one more with one of the pattern tools.
Made it in black and white. Just the eyes and the nose in color.
Cat Version 2 photo - Small

A little fun :-)

That’s all I have to give you now Hope it helps you.
