|Welcome to Meet the GIMP.

| Today’s tutorial is not about raw converting but about new coding while doing a real show and to correct some errors from the last tutorial.  

| As you can see the sea is a bit dull and it’s just gray with not much definition in it and when I switch off the sea layer here and the other layers, you can see there is some definition in this sea.  

|And when I look at the layer mask you can see that I used a layer mask which is mostly gray for the area I wanted to show.  

|So let’s redo this step again.   

|I have deleted the sea layer and made a copy of the background layer.

| I name the layer as sea and place that layer below the sky and above the land.  

| I could have worked with the layer I had but I wouldn’t have got a good result because I had used the curves tool to get the sea a bit darker  

| And with that I have destroyed a lot of the colour information which was present in that layer and I’ll get a better result this way here.   

|Now I again add a layer mask to the sea layer, I use the gray scale copy of the layer and add it.   

|I click on Show layer mask and edit the layer mask.

|I will use the Curves tools and I’ll repeat the same procedure by pulling this down but this time I’ll pull this upper curve up.  

|To correct some missing structure here I select the brush tool and choose a bigger brush here and start painting the land area with black colour.   

|I don’t want to paint the sea layer with black colour so I exchange the foreground and background colour.  

|This area here, I think it was quiet well but you can correct that later on.  

|So let’s choose a soft brush and see that we get this edge here fine.  

|When I disable, show layer mask we can see the stretch scene here on the border between land and sea.

|Now I go back to the full image with shift + ctrl + E.  

|I select the curves tool and check if I have layer mask selected and I include the sky layer to see the whole image and now I click into the image and play with the curves.  

|Now you can see the halo between the sea and land vanishes but the sea is now again bit dull.   

|Ok, I can adjust with opacity slider the effect of curves tool and I think I should make it a bit less for a good effect.  

| And we can decide the right amount easily.

|And I think I have done too much with this part so I slide the slider down and I think this is ok.  

|I deselect the sky layer and check but it’s not because of it.

| So I deselect the sea layer and its because of sea layer.   

| And for doing that I use the gradient tool.  

|I select the layer mask and now select the gradient tool from the tool box and I want to have the land part white and sky part black and I want to have the border here.

| The gradient starts with full white and ends with black.

| So I zoom into this part,I select the gradient tool and  start around here.

|  While making this line I am pressing ctrl key and left mouse button and pulling in order to get a straight line and leave the button here.  

|You see it worked, the brightness on the horizon is gone and you can see that the layer mask of the land is gone too.  

|So this wasn’t the good way to deal with the horizon so I undo this step here.  

|Now first I select the rectangle and check if layer mask is selected and draw the rectangle in the sky part.  

|Zoom into the bright part here and select the layer mask.  

| I want to have black above and white below, so I start from here, go straight up to the horizon and now you can see  the sea is only white and land and sky are black.

|Shift + ctrl + A, disables all selection, shift +ctrl + E goes back to the whole image and  a lot better now.  

|I want to edit the sky layer in the same way like I did for the land layer.

| Just double the sky layer and switch to over lay mode.  

|This is way too much so I pull down the opacity slider a bit and we have a bit more contrast in the sky.  

|This is the case for dodging and burning.   

|Dodgging and burning is a term out of the dark room days, where you can  dodge  a picture by keeping your hand or paper or something else in the light beam of the enlarger between the enlarger and photographic paper and burning is opposite of that.  

|It’s quite tedious procedure to figure out which step to be done at what time and you need a lot of sheets of paper for that and when you want to look at such a process, I recommend you to look a film Well Photographer.

| It’s a film about James and it’s a terrific film even without this a dark chamber seen.  

|Now let’s see dodgging and burning process.

| We have a dodge and burn tool in the tool box here but I would like to work again with layer.  

|This gray colour is 50% gray and I switch the layer mode to overlay and you can see nothing has happened.  

|Now I switch the colours to black and white and select a brush.

|This brush size is about right.But I decrease the opacity tool let’s say 30% or so.  

| Now I make sure that I have the new layer is selected and change the foreground colour to white and background colour to black and I start to paint the wall here.  

|And perhaps you can see it that the compression has done its work and the side of the wall is brightens up.  

|This process is called dodgging because I am keeping the light on the photographic paper and so the wall gets brighter.  

| When we look at the layer here you can see that I have a whiter area here and there are some other parts of the image which could be a bit lighter.  

| I should pull the opacity slider a bit down and this is ok.  

|I think the horizon is very bright so I adjust the circle size of the brush to paint that part and use black colour to darken that part of the image.  

| So undo the step.  

| You can see the technique that I made a layer and made it medium gray & 128% for each channel and change the layer mode to Overlay.  

|  Medium gray and Overlay mode does nothing and you can paint into the image with white or black.

| While painting with white you make the image a bit brighter with black you make it darker.  

| I wouldn’t work again on it except some of you finds a mistake in the edits I have made today.

|I hope I haven’t done that and name the layer as dodge and burn.
