Lesson 5

 

Digital Camera section

 

 

An exercise in depth of field in relation to portrait photography. Using the lock down technique take a picture of someone in the class, make sure the focus is on their face, and if possible open up the aperture as wide as possible, then take some shots.

An explanation of "depth of field"


See the following links for further reading

1 Depth of field simplified or this one

2 Medium Depth of field explanation

3 Technical http://www.normankoren.com/Tutorials/MTF6.html


An example of depth of field in action

Composition 2 (divisions of an area - The golden mean rule, left to right rule, the directions subjects look in.) further reading link 1


The direction in which a subject looks influences how the composition works, in this example the figure on the right "bounces" the onlookers gaze back to the figure on the left, who in turn focuses our attention on her eyes and face.

 

Photoshop section

 

Selection techniques

To do anything (change, delete, filter etc... ) either a part or all of an image one must firstly select the area

Deleting selections

Adding to and cutting out selections using the shift and ALT keys.

Filling and stroking

Multiple selections

The lasso, polygon lasso and the magnetic lasso

 

End of lesson 5

 

Lesson 6

 

Using a digital camera section

 

Group pictures, a problem of resolution? If you need the details of peoples faces your camera may not be able to capture such fine details. Always set your resolution to as high as possible for group pictures. It might be worth using a higher quality file format such as TIFF or RAW for important group shots.


If you use low resolution settings the individual faces may appear blocky when you zoom in to look at them

Lesson 7

 

Digital camera section

Managing pictures ( Making copies, creating subfolders)

Be aware that some cameras allow you to create folders on your memory card, you may also be able to make copies of pictures which are set at a different resolution to the original. This is useful if you are running out of storage space and need to take more pictures. Firstly delete unwanted pictures, secondly lower the resolution of any pictures you may take from then on during that session. - Check out other ways to lower the amount of memory a picture takes up, settings such as quality and compression will also have an effect - . If you're still lacking storage space you might be able to use the copy function. If you do so, save the new one at a much lower resolution. For instance you may have a picture that doesn't need to be saved at high resolution - approx. 2400 x 1600 - so you make a copy which is 600 x 400 and then delete the original. By doing this you'll have gained enough space to shoot 15 pictures at 600 x 400. A useful feature in emergency situations.

Putting a zoom feature to use

Firstly if your camera has a digital zoom avoid using that feature. If it has both an optical and a digital one then try to only use the optical one. A digital zoom is just an enlargement of a part of the ccd chip that senses the image in your camera, you may as well crop your image and enlarge it in photoshop than use a digital zoom.

If you have an optical zoom however it can be put to many uses. The first one is to zoom in on things that are distant, but it can also be put to less obvious uses. Firstly when wanting to take a close up of someone's face you'll find that if you hold a camera too close it will distort their features and will probably be hard to focus. Holding things close to your eyes makes the things look bigger, the closer they get the larger they look, we all know this - hopefully -. From your eye to about a foot away you will see the most dramatic effect. Therefore if you have a person's nose 7 inches away from a camera lens and their eye is 8.5 inches away the nose will look disproportionately bigger than it should in relation to the eye. The face may even look like a caricature. If you want to overcome this then step away from your subject and frame your picture around their face using your zoom, it'll be far less likely to distort their features.

There is an area between around 3 foot and 1 foot from your camera that many cameras find hard to focus on. If this happens move away from your subject and use your zoom to get the close up you require.

When zooming less light comes in to the camera. The speed of a lens denotes how much light it can let in, a faster lens will be able to zoom in on subjects in darker situations than a slower lens. Remember if you're not able to get enough light to take a picture try zooming out, you might find more light comes through the lens.

If you take a picture using a flash you might find that being close up to a subject washes out (over exposes) the image, if that's likely to happen take a picture from further away using the zoom, that way the luminosity caused by the flash won't be so intense.

 

Flash guns

For those of you who wish to get into photography in some depth:

Does your camera have an interface for an add on flash device? This will either be a plug in socket for a "flash cable" or a slide on socket known as a "hot shoe". If you can add a flash gun you'll find a bounce head one can allow flash photos to be taken with a far more subtle effect.

 

Photoshop section

Colour range select tool

This technique is particularly useful when you have an area that's got lots of things in front of it, such as sky or a wall might have.

Sometimes you'll have an area, or multiple areas of a picture that consist of a colour range. For example a sky is often of a similar hue, so if you wanted to select the sky this feature might be useful. Go to the "select" drop down menu and choose "Color range". A window will appear. Choose the pipette with a plus sign next to it and start clicking on the area you want to select in the picture. A black and white image will show you what area will be included in the selection. If too large or small an area gets selected adjust the fuzziness slider and see if that has a positive effect. When the area you want to select is shown in the preview window to have turned white click on "ok". If you find extra selections outside of the area you want have also been selected you can tidy up the selection by using the lasso or polygon or rectangular marquee while holding down the ALT key to de-select those areas. If certain areas within the area you want to select are not selected use the selection tools while holding down the SHIFT key to get rid of them.

 

The "Replace Colour" function

Here's an orange house

Have a go at changing the colour of the house using the replace colour tool. (Image > Adjustments > Replace colour)
If other areas of thepicture change colour too then either select the area you want to use before using the replace colour function or lower the fuzziness setting in the replace color options box.

Uses. make a lst with the group of uses.

 

What is TWAIN

TWAIN is a widely-used program that lets you scan an image (using a scanner) directly into the application (such as PhotoShop) where you want to work with the image. Without TWAIN, you would have to close an application that was open, open a special application to receive the image, and then move the image to the application where you wanted to work with it. The TWAIN driver runs between an application and the scanner hardware. TWAIN usually comes as part of the software package you get when you buy a scanner. It's also integrated into PhotoShop and similar image manipulation programs.
The software was developed by a work group from major scanner manufacturers and scanning software developers and is now an industry standard. In several accounts, TWAIN was an acronym developed playfully from "technology without an important name." However, the TWAIN Working Group says that after the name chosen originally turned out to be already trademarked, an 11th hour meeting of the group came up with TWAIN, deriving it from the saying "Ne'er the twain shall meet," because the program sits between the driver and the application. The name is not intended to be an acronym.

Panoramic shots

Using the crop technique


Panoramic camera or special lens? No just a crop of the image below

 

 

 

The canvas size function in Photoshop allows you to make more space around an image so you can insert images next to it.So for example this technique can be used for panoramic images as you can see below.
