Intaglio

Intaglio printing - a printing process that uses an etched or engraved plate; the plate is smeared with ink and wiped clean, then the ink left in the recesses makes the print.

Equipment need:

  • Perspex plate
  • Etching tool
  • Caligo printing inks
  • Scrim
  • Watercolour paper 
  • Printing press
By Using the sharp etching tool you make marks into the perspex plate, by using different pressures, techniques and tools you can control how dark or light the marks are.


You then rub small amounts of caligo ink 
into the lines made and then with scrim, work 
in a circular motion ensured the ink is 
pushed in. 
 
By using the scrim make sure any excess ink is wiped off the plate, if too much ink is left on the plate your image will not show.

Then lay the etched plate on the printing bed 
and on top the plate lay a piece of 
blotted piece of watercolour 
paper. Cover with the felt blanket and roll 
through the printing press. Lift the 
print from the plate and place on a drying rack.



 





Health and safety:
  • Keep area tidy
  • Keep area ventilated
  • Wear protective clothing
  • Use a cutting mat

Click the Levels or Curves icon in the Adjustments panel.



Using the pen and shape tool

In the tool bar, select the DIRECT SELECTION TOOL.  Image

Now select the PEN TOOL.  Image

Move your PEN TOOL to the middle of your artboard, but don’t click your mouse. Just let it sit there.
 Press and release your COMMAND(Mac)/CONTROL(PC) key a few times. Notice how the PEN TOOLturns into the DIRECT SELECTION TOOL Image

Usually before I select the PEN TOOL to create a path, I will click on the DIRECT SELECTION TOOL so it will be the last selection tool selected. This tool allows you to select and move points individually.

If a point is solid in color, that point is selected or “active” and can be manipulated. Points that are not selected will be open or white in the middle.

Image

Therefore, if I am making a path and I see a point that is not placed properly, I can hold down theCOMMAND(Mac)/CONTROL(PC) key and my PEN TOOL becomes the DIRECT SELECTION TOOL and I can easily select the point I want to move and reposition it.

Image

When I release the COMMAND(Mac)/CONTROL(PC) key after I have made my adjustment, the DIRECT SELECTION TOOL becomes the PEN TOOL again. At this point you will need to click on the last point you set with the PEN TOOL to continue your path. This trick will greatly increase your speed with paths because you can edit your path as you go.

If you are making a path and you hold down the OPTION(Mac)/ALT(PC) key, your PEN TOOL becomes the CONVERT ANCHOR POINT TOOL and you can adjust the handles individually in your curves.

To make the curve handles visible, hold down the COMMAND(Mac)/CONTROL(PC) key (to switch to theDIRECT SELECTION TOOL) and click on the path on the side of the point that you want to adjust and the handles will appear.

Image

Now back to holding down OPTION(Mac)/ALT(PC) and the CONVERT ANCHOR POINT TOOL to grab and adjust the handle.





Sewing

Machine stitch.



1.Place the spool of thread on top of the machine and pull the thread over to the first metal hook. Slide the thread under then pull it forward for the next step.

2.Bring the thread forward and down the space directly in front of the top hook. Wrap the thread under the tension dial and go back up to the internal hook. This can be adjusted using the hand crank on the side of the machine. Thread the thread through this internal hook and continue to the next step 

3.Bring the thread down towards the needle. Run the thread through the spring looking trap and then to the needle itself. After it's through the needle run it through the foot. Lead the thread out the back and move on to the bobbin.

4.Insert the bobbin thread into the bobbin. Pull thread into notch on side of bobbin. Slide the thread under the metal flap until it snaps in line with the hole on the side of the bobbin.

5.Insert the bobbin into the machine. Use the hand crank on the side of the machine to insert the needle and make one revolution. Use a ruller or other slim device to pull the two threads out and you're ready to sew.

Health and safety
  • Make sure that robust needle guards fitted and used
  • Carry out a risk assessment on the provision of eye guards
  • Check that lighting is adequate and stays on when the motor is switched off, eg for safe threading.
  • Vee belt and pulley drives are guarded
  • Seating allows for good posture and ease of movement
  • Electrical wiring is supplied from overhead or otherwise to avoid cables on floors
  • Where automated making-up machines are in use, give special consideration to additional guarding requirements
  • Put a system in place to inspect guards, needles and work areas on a weekly basis
  • Guards should be adjusted for each individual operator's finger size
  • A safe system of work includes removing feet from treadle when threading and changing needles
  • Power should be switched off when carrying out adjustments and needle changing

Hand stitch



  

Health and safety of hand stitching:
  • Keep hands away from the needle as it is very easy to stab yourself when hand sewing
  • Use the right thread, thick thread for hand stitching
  • Make sure the needle is sharp
  • Put the needle where you can see it as it is easy to lose it.
  • Concentrate at all times
  • If you are tired, distracted, anxious, upset, rushed or tipsy, you are putting yourself at unnecessary risk of injury
  • Keep your work area tidy. Sweep the floor for stray pins; don't keep boxes or bins stacked up where you could run into them.
  • Sewing requires working with sharp objects, like needles and scissors. All of these will pierce or cut you very easily.
  • Put all needles and thread away when finished with it

Frottage

Frottage

   
 [French, from frotterto rub, from Old French froter.]


Place a composition of textured materials on a piece of card and place a piece of paper over the top. To make your rubbings you can use any type of pencil, but best to use is a graphite stick.
Note: when using the graphite stick hold it at an angle not straight down as this creates lines and streaks.

Equipment:
Card
textured flat materials
scissors
glue 
paper
graphite

Creating niches
 


Equipment:

  • A cutting mat
  • A cutting knife
  • An old book
  • PVA glue
  • Clothes pegs


Health and safety:
Be careful with the cutting  knife as they can be quite sharp
Keep area around you clear for others and yourself

What is a Niche?
As the name suggests, it is a "hole" cut through one or more pages of a book. This creates a space that altered book artists and other arts and craft people use for multiple purposes.

Step by step
  1. Decide how you intend to fill the niche. This will determine the size and shape.
  2. If you are using a 3-D element, a key, for example, you will need to determine how many pages you must cut through. Place the key on the outside edge of the book's pages to determine the desired thickness. If you want your book to close flat afterwards, you must make your niche a little thicker than your key. (Some AB artists don't care if the book doesn't close; it's up to you.)
  3. Decide the placement on your page. Cutting a thick opening close to the spine will result in an unsightly ridge of cut pages that will stick up and prevent your book from closing properly. Alternatively, cutting a thick niche too close to the outer edges will create undue stress on the spine and possibly lead to damage.
  4. Decide on the shape you want to use. Squares and rectangles are the easiest, but you can cut any shape you want.
  5. Using a pencil and ruler (if you want a straight line), draw the niche on your top page.
  6. Place a cutting mat underneath the last page that you intend to cut. By cutting mat, I refer to a hard surface that will prevent you from cutting through to pages that you want to protect.
  7. Fasten your pages with the clothes pegs to hold them in place while cutting. 
  8. Cut your niche using the knife.
  9. If your niche is thick, you will not be able to cut through all pages at once. Cut through as many pages as you can, then using the last cut page as your template, cut some more. Continue until all desired pages are cut. 
  10. In most cases,the inner edges of your niche will be messy. Many of us don't care, believing this to be part of the charm of an altered book. If you do care, tidy up the inner edges by cutting, sanding, painting, etc. Another approach is to line the entire niche, including the edges, with paper or vellum.
  11. Fasten together the pages used for the niche.
  12. Fill or decorate your niche as planned.

Print

Printing
Additive method monoprinting with collage
  • The additive or light-field method, in which the image is painted by adding or building up pigment onto the plate


Collage monoprints 
The term collage is not used in its traditional meaning; materials are not glued on the surface but are used on the paper either inked or not inked. Materials often used are cut or torn shapes from textured papers, lace, cloth, thin vinyl sheets, leaves, and even metal grating.

Reductive method monoprint 


  • The reductive or dark-field method where the entire plate is covered with a thin layer of pigment, which the artist then works out his image by removing some of the pigment with brushes, rags, sticks, or other tools.
Stenciling with monoprint
  • By using stencils made from card or pre-made you can create easy and effective designs.

Painterly method monoprint
With this method you paint the shape onto the plate, you can create extremely colourful designs, you can also create effect using layers with this method.



Painterly method video step by step

Equipment
  • Heavyweight vinyl
  • Mylar or acetate
  • Masonite
  • Discarded thin litho zinc or aluminium plates
  • Oil based ink or (Akua-Kolor, Createx)

Health and safety
  • When using the press mind your hands with the wheel and the press itself.
  • Keep work area clear
  • Do not leave bags, coats or other items around the floor or desk.

3D Ceramics



Ceramics
Equipment needed:
Clay
Cutting tools
Slip
Coloured slip (optional)
Glaze

 My own procedure:
1. My first task was to design my ceramic tiles on a piece of paper, this makes you consider the composition of the piece, however some people may not feel the need to do this. I then created one A4 sized tile with my design on it, after doing this your piece had to be split into 3-4 pieces to create a new design. After applying the color glaze and colored glass the tiles then went into the kiln.

2. I then created a 3D ceramic, I chose to make a prism with four sides and a base using slip. Then I created a new design based on my results of my first task and added it to my prism. I made two prisms in this task and created designs on both of them, I then proceeded to paint my ceramics and they were put in the kiln.

Health and safety
  • When using tools you should always be aware
  • Clean your area, clay leaves a lot of dust behind that is bad for other people's and your lungs.
  • Gloves are provided if wanted
  • Keep items off the floor e.g coats, bags etc
  • Be aware of your surroundings in the kiln




Macro

MACRO

A lens having a reproduction ratio of 1:1  
Macro photography is taking extremely close-up images of subjects. The technically correct definition would be to take an image at a 1:1 ratio but, in general usage, the term has come to mean any close-up photography.

Macro capable photography lenses are marked with magnification ratios such as 1:1 or 1:5. A 1:1 ratio means that the image would be the same size on film (negative) as in real life. A 1:5 ratio would mean that the subject would be 1/5 the size on film as it is in real life. Due to the small size of 35mm negatives and digital sensors, a 1:5 ratio is nearly life size when printed onto 4"x6" paper.


From Makros – a Greek word meaning large, l  o  n  g 

• Macro is the term used to describe photographs 

where the subject is recorded as life size or up to 

10 times bigger than life size. 




Close-up is where the subject is recorded 
between one tenth of its actual size to life size. 



 
Any small detailed items can be used and arranged into a composition, when capturing macro photography a tripod is essential as your focus area is extremely small and hard to capture if you are not completely still.


The greater the magnification used, the 
shallower your depth of field becomes. The old 
rule of choosing the smallest aperture possible 
stands true, but only to an extent. At apertures of 
f/22 or f/16, a loss of general image sharpness 
can occur through diffraction

(diffraction - the process by which a beam of light or other system of waves is spread out as a result of passing through a narrow aperture or across an edge, typically accompanied by interference between the wave forms produced.)


Equipment:

DSLR, Set of x3 extension 

tubes (12mm, 20mm, 36mm), light trigger and receiver, 

hand held light meter, lighting equipment, light table, 

black and white backdrops. 

 If the camera is set to f/16 and you 

are using a 12mm extension tube the light meter will 

need to read f/16.5 (half a stop brighter). If set to f/11 

on camera and using a 12mm extension the light must 

be f/11.5. 

Possible lightings:
  • Daylight
  • Artificial light - torches or table lamps
  • Off camera flash
  • Ring flash - ideal (expensive)
  • Use absorbent or translucent materials out of shot to add, reduce or diffuse light
Beware of shadows!

ISO – 100 ISO is ideal but you may need to increase this if 

light is low 

Shutter speed – if your subject is completely still and you 

are using a tripod, then shutter speed can be anything you 

like! You may wish to increase this if your subject is 

moving. When using studio flash you should use 1/60. 

Aperture – depth of field is very limited so this suggests a 

small aperture. However image quality will be reduced at 
very small apertures. Somewhere between f11 and f16 is 
generally an acceptable compromise. 





 Own images using 1/60, 100ISO and
f/11, focus ring set to infinity.

    • Do not touch the bulbs at any time, especially after use, as they will be hot.
    • Do not knock the bulbs when fixing light accessories to the unit.
    • Do not put the protective plastic cap over the bulbs until they have 
    cooled. Leave the light accessory in place until ready.
    • Do not leave lights on when not in use

    It is important to keep your work area safe
    • Leads should be kept tidy and either taped to the floor or covered 
    with rubber mats
    • Do not leave coats and bags on the floor
    • Do not set your equipment up by a door way or in front of a fire exit
    • Act responsibly when around expensive and fragile equipment.

    Mode
    1. 2. 3.
    1. Ambient light (available)
    2. Flash (not connected)
    3. Flash with Sync lead



    Extension tubes
    Extension tubes are used for close up, macro work. They
    generally come in three different sizes; 12/13mm, 20/21mm & 
    31/36mm (note the sizes may change depending on the 
    make). One or a combination of extensions increase the 
    magnification of the lens and are attached to the camera in 
    between the camera body and the lens itself.


    Own images using extension tubes: 

    When using extension tubes you need to set the focus ring on your lens to
    infinity. To focus your image you will physically have to move the camera closer or
    further away from the subject. You should also set your lens to a small aperture

    (f/16) and adjust the lighting units accordingly until you get the correct reading,
    remember the table above. Example: if you are setting your camera to f/16 and you
    are using a 31mm extension, you need to make your lighting brighter until your light
    meter is reading f/22.5 (f27)




    1. High-key lighting is a style of lighting for film, television, or photography that aims to reduce the lighting ratio present in the scene. This was originally done partly for technological reasons, since early film and television did not deal well with high contrast ratios, but now is used to suggest an upbeat mood.
      1. Low-key lighting is a style of lighting for photography, film or television. It is a necessary element in creating a chiaroscuro effect. Traditional photographic lighting, three-point lighting uses akey light, a fill light, and a back light for illumination.


    Aperture and shutter speed

    What is Aperture?

    Put most simply – Aperture is ‘the opening in the lens.’
    When you hit the shutter release button of your camera a hole opens up that allows your cameras image sensor to catch a glimpse of the scene you’re wanting to capture. The aperture that you set impacts the size of that hole. The larger the hole the more light that gets in – the smaller the hole the less light.
    Aperture is measured in ‘f-stops’. You’ll often see them referred to here at Digital Photography School as f/number – for example f/2.8, f/4, f/5.6,f/8,f/22 etc. It can mean the difference between one dimensional and multi dimensional shots.
    Depth of Field (DOF) is that amount of your shot that will be in focus. Large depth of field means that most of your image will be in focus whether it’s close to your camera or far away.
         
    These images have a small depth of field (DOF)
          
    These images have a large depth of field (DOF)
    Depth of field examples using F numbers:

    Nikon Digital SLR - D40/D50/D3000
      The mode dial is the small circular knob on the top right of the camera on this picture this controls the aperture priority, the circular dial beneath the mode dial to the right is the main command dial; this changes your aperture when using aperture priority.
    The F number and shutter speed are displayed on the camera's digital screen, for example the F number on this camera is f 5.6 and the shutter speed is 1.
