Pictures comparison

As a plus and to help you to see what might be the best option for you, I leave here the same pictures after treated with the different methods I posted.


Cavalier 03 (PhS)
With Photoshop Unsharp Mask


Cavalier 02 (PhS)
With Photoshop High Pass Filter


Cavalier 02 (G)
With Gimp


Note:  The High Pass photo is grey because I preferred to leave it this way.  The original colour of these statues is greyish, they look sepia because of the candles light  (it’s a monument inside a church).

Sharpening a pic

Sometimes it may happen that you may want to fix a mistake in the focus of a picture.  This can be done in three ways, two with Photoshop and one with Gimp.  I will explain them all, but be warned  it won’t fix serious problems.


Banner P04


First method

  • Duplicate layer  (Layer => Duplicate layer).  Now you have two layers looking exactly the same.  You’ll work on the top layer, been the original picture the background.
  • Apply the  “unsharp”  filter  (Filters => Sharpen => Unsharp Mask).  Despite the name, what it does is sharpening the image according certain parameters you select.
  • Regulate Amount, Radius, & Threshold.
  • Save the image by exporting to your favourite  (preferably JPEG).  This will flatten merging the two layers into one picture.

Second method

  • Duplicate layer  (same as before).
  • Convert the duplicated layer into a Smart Object  (Layer => Smart Object => Convert).
  • Apply High Pass filter  (Filters => Others => High Pass Filter).  Regulate the strength and accept.
  • Be careful when set the radius, too much will make the image look odd.  But don’t worry, if you make a mistake, just undo it and apply the filter again.
  • Now the image look all grey but this is easy to be fixed, whether applying a Photo filter  (Image => Photo filter)  or setting High Pass to Overlay mode  (see picture below).  Additionally, you can regulate the opacity
  • Export the image as explained before.



Banner G04

Just one…

  • Apply the sharpening filter  (Filter => Enhance => Sharpen).
  • Play with the controls at will.  If you don’t like the result, just undo and start over.
  • Export your image as JPEG  (or other format)  with the highest quality.



Yes, I did it on purpose.  I left the easier an more effective for the end.  Choose wisely.

Exporting layers as independent pictures


Some people may find it useful, some people not.  Here it is.  Adapted and translated from an original “Desde Linux” article in Spanish.


Installing the addon

First of all you need a script, available for free download and use here:

After you need to put this script either on the system folder  /usr/share/gimp/2.0/scripts   or in your user folder   /home/youruser/.gimp2-8/scripts

Then, when you open Gimp, you’ll find in the File menu an extra option:  Export to Save all layers.

An image just opened with The Gimp



Using the addon

If you’re editing a picture using layers, this addon will be helpful.  After working on your image, if you need to save your layers as separated pictures you can click on  File => Save all layers.  Click there and a small window will pop up.  Here you can modify the renaming pattern for all layers.  Each name will be modified by its position on the original picture.  You can also choose what format you want to export to.

Where in the menu

By default the script saves all new images (layers) to the same folder the original picture is.  As far as I know, you can’t tweak this but you can move the images later on.

Script on work.



Final note:  Given the developer of this script is from Spain, you may see a  “Guardar capas”  in your menu instead of the translated version.  It’s okay, it’s just lack of translation.

It could be the banner 3

In my quest for making a banner suitable to the new Arts & Design Series of articles in Fedora Magazine, Paul Frields gave me some nice ideas. I couldn’t make it to give those ideas a good look but some nice things came up in the process.

These are some of the results:

Original image with text only.

Text was added with Digikam/Showfoto.  Yet not easy but better than Gimp.


Same image with B&W effect to highlight the text.

I won’t say what programme I used for this one.  I’ll be thrown into the bonfire.


Con arts (localised effects)
Same image but with some painting effects on furniture.

I left limpid central image and text to apply a hand painting fuzzy effect on furniture.

Still working on Paul’s ideas…


Note:  All pictures have been resized to fit in my slow connection.  If anyone is interested in them, I can send the originals once I’m on a decent WiFi.

It could be the banner 2

Well, there was some discussion over the meetings and mailing lists and now I’m posting the original photo and another version.

After these ones I’ll start with a new idea and post the results.  Let’s see where this end up.

Original photo as I took it with a mobile.


Laptop with some letters
Banner with letters. Note the font type, Grand Hotel.


As I said, it’s a pain adding text with Gimp so I used a mobile app.
