Photoshop Workshop 1


When displaying images on screen on photoshop, it should be 300 pixels per inch. Web images are only 72 pixels per inch, therefore making it larger won't keep the same quality. Therefore when taking images from the web, remember they can not be scaled up, as when printed. it will be very pixelated.

Colour Mode;

Use RGB in the colour mode because it works better on screen, and this is what we are doing, and it is more accurate. It's none destructive to the image when you are working in RGB, so don't change the colour mode to CMYK. Photos are taken in RGB colour mode, straight from the camera, as camera's captures light.

You can tell what colour mode the image is by going to 'image' then to 'mode' and then the option will be ticked. Therefore this shows that the colour mode is RGB. Changing the mode to CMYK is destruactive because you can't bring it back. although you can see what it will look like when printed.

By going to 'view' the 'proof colour' you will be able to see it in CMYK mode, without changing the colour mode perminently.

Then selecting 'view' and gamut warning, this shows you what colours are not available in CYMK mode.

To bring the colours back into the colour range, you can select the half circle in the bottom right, then use some of the options, trying levels. this creates a new layer where you can experiment with levels. If it doesn't work delete the layer and try something different, for example, hue and saturation.

Changing the hue and saturation to get colours which work when printed out. You can also hide this layer so that you can compare it to the CMYK proof colour view of the image, so that you can see which you prefer.

Manipulating the Image;

Changing the levels so that you can make the bottom of the image more visual, but then bleaching the entire screen makes it look too light, therefore select the level box (white box in layers) then go to paint brush, and paint over the parts which I want to go back to the original colour.

Hard mask.
Soft mask.

Making sure the hardness or softness of the paintbrush is important, as you can see it makes a lot of difference in the image. Using the hard stroke make the line very distinct, and it is really clear that the image has been manipulated, and it looks messy and rushed, where as the softer stoke is more subtle, and works a lot better. To do this just paint over where abouts you want the image to return back to its original state.

As the picture is shadowed on the statue, you want to be able to see the detail in the statue therefore go on the quick selection tool and select the statue to change it. This can only be done if its the image in the front which is shadowed, as if it is the background which has blocked out, you can't retrieve that detail.

To get the detail back into the shadowed statue, you bring the middle scale colour and highlighter up on the levels adjustment, therefore it bring the colour and shade back into it.

There were slight gaps in the statue, therefore to get them back to what they originally were by selecting the magic wand tool. selecting all the gaps, then going to 'edit' down to 'fill...' then change the content to black so that they will go back to the original sky colour.


When producing a panorama automatically on photoshop, first have a blank page, go to 'file' then down to 'automate' which takes you to the screen below.

There are many different settings and effects you can use doing this, but for this we have left it as 'auto' then went to 'browse' and found our images. Then simply click 'ok' and it will automatically produce the panorama for you.

When it came up I found that it worked but the images were a bit scattered with rough edges, therefore you can use the 'crop' tool to make it look more professional.

This is the finished panorama, after we have cropped the images, and it looks really good, and is seamless.
