How I photograph my Paintings...

Here is my unscientific, nontechnical, way to take photos of your acrylic paintings!

I've read about more technical ways, and I somehow still can't figure it all out! So over the years I've done lots of trial and error, and this is what I come up with... It's not perfect, but works well enough for my needs...

I use a fairly good camera, but not really pricey. Its a Canon PowerShot SX20. I liked it because it has a lot of zoom on it. You can do all the manual adjustments, but I don't know how and just use the auto setting.

So here is what I do:
  • Photograph before you put on any final glossy finish. Glare is a big problem to overcome with acrylics. Even outside in open shade a Charles mentioned, I get glare
  • No flash (just more glare, washed out color)
  • Use a tripod and the delayed setting on the camera. I use 10 second delay. Don't move a muscle until it goes off. This is important because I shoot in the lowest light I can to avoid glare, so you can't have any wiggle at all.
  • I set my painting on my easel - raise it up above the lip of the easel with  a piece of wood under the canvas. Set against an interior wall as straight up as I can without it falling over. Choose a wall that gets no direct light at all.
  • I just use my overhead daylight fluorescent lighting that is in my studio.
  • Place your tripod far enough away that you can zoom in just a bit - otherwise the edges of the canvas will look rounded. The whole setup is usually pretty low to the ground - this seems to help with light coming in from any windows.
  • Adjust the angle of the camera to get the sides as straight, and bottom and top of the canvas as horizontal as you can.
  • Put a piece of white paper behind the painting - but still in the frame so the camera can see it. This helps the camera with the color but it also helps later when you are adjusting in photoshop. You can use it to correct the "color cast"
  • Use your 10 second delay and shoot!
I know this is a total workaround. But I am the workaround queen. :)
The adjusting I need to do in Photoshop elements is usually just to:
  • increase the contrast
  • correct the color cast - using the white paper as the spot to click on. Some area of the white will usually bring the colors close to the original
That's usually all I have to do to be pretty close!

Learn about Values! Step by Step! Class #3

The Magic of Values in the Acrylic Landscape. Class #3
by Karen Ilari 


COLOR!
So now that you have a clear idea of what VALUES you want in different areas of your painting. Let's translate that into color.

First: Each color as it comes from the tube has it's own starting value.
For example Hansa Yellow Light is fairly light. Alizarin Crimson fairly dark

Second: You can make a color lighter by mixing with white - or with another light color. You can make a color darker by mixing with black or another dark color

Third: Light and dark colors - think sunlight and shadow - can be either "warm" (leaning toward reds, oranges, yellows) or "cool" (leaning toward blues, greens and purples). You can have a COOL yellow and a WARM yellow, for example.



Mixing Colors is a process. In acrylics you do a lot of mixing as you paint, because the paint dries on the palette. You can't mix up your whole color plan in advance. So, you start by asking yourself a series of questions. What is the base color - the tube color nearest - Start with some of that
  • Is the color more red?, more yellow? etc. keep mixing til you get the right color
  • Is it lighter? darker? Adjust for that
  • Is it greyer - more muted? Add the complimentary color to grey it
  • Is it warmer or cooler?
Exercise #1 Mixing Values in Color
Supplies:
            Heavy Body Acrylic Paint: Mars Black and Titanium White, Ultramarine Blue, Pthalo Blue (green shade), Alizarin Crimson, Napthol Red Light, Quinacridone Magenta, Hansa Yellow Light, Hansa Yellow Medium, Qunacridone Nickel Azo Gold.  
            Flat synthetic brush - about 1/2" wide
            Water container, paper towels, palette
            Watercolor paper        



When mixing lighter colors with acrylics, it's especially important to realize that if you use just white, your color will get COOLER as well as lighter. This is seldom what we want in landscapes. Usually the sun has a warming effect, so when we want to paint an element in sunlight it needs to be lighter and WARMER   

So let's practice and see how our colors work with values

  • Start with each of your tube colors. Paint a square of it.
  • Determine with your value scale where the starting value is.
  • Mix colors to match the remaining values on the scale. 
  • Make one string for each color using JUST WHITE to make the lighter values. 
  • Then make a string of the same color using YELLOW or RED, along with white 
 It will look something like this:
Here I have used Napthol Red Light.
The top line using some Hansa Yellow Light as well as white.
Do you see how cool the lightest tone in the all white line is compared to the one with more yellow?

The Ultramarine Blue is similar - the all white is on the first line here. I've added a little Napthol Red on the second line.

Using Hansa Yellow Medium and Quinacridone Magenta would give different color tones. But you can wee the idea of WARMER and COOLER here.

What about going DARKER!?
The Darker colors above were Mixed by adding ind Some Alizarin Crimson, and some Ultramarine Blue to the Red as well.
You can use Mars Black or another tube black for mixing darker colors. But I find that tends to make duller, flatter colors.


 I prefer to use a mixture of these colors for my black
Pthalo Blue - 1 part
Quinacridone Gold- 2 parts
Alizarin Crimson - 3 parts

This makes a very transparent rich black which mixes well with other colors. You can push it to be more Blue, Red, or Green by adjusting your amounts of each color.
Try mixing up this combination of colors, and compare it to Mars black on your watercolor paper.
Add some white to each one to see how that compares. As your mixture gets lighter it becomes more apparent what color you are leaning toward. If you want a more pure grey, you just mix in a little of the complimentary color. If it is too green add a bit more Alizarin Crimson for example.
Next mix each type of black with a tube color. Then add white.
 
 Mars Black is on the left. The mixed black on the right. 
Then adding white going down the page.
The lower set is each black mixed with Ultramarine Blue, and then white. 
I find adding Mars Black deadens other colors in a mix. And what your really want to avoid is having dull darks. Especially in a landscape you want to keep your colors in the dark shadowed areas lively and interesting.
LAYERING
The technique I use most often in painting the landscape is Layering. What do I mean?
Simply developing the image by building up layers of paint. This gives you lots of room to refine your shapes and brushstrokes. Here's a detail from my painting "Saturday St Johns" to illustrate.
Notice especially the tree area:
  • Start with your dark shadow values first - Add mid tones and highlights on top
  • Start with thinner layers of paint, use more paint to make thicker layers as you layer
  • The top brushstrokes are the thickest
  • Keep the final brushstrokes spontaneous - don't over brush them
  • If you don't like the brushstroke, shape or color - make another layer!
I use a small round bristle brush when making foliage. It is well worn and ragged. That's a good thing! It gives you natural random marks.
I use the brush mostly on its side, in rolling and tapping motions. Don't forget to soften the edges where you need to and leave some crisp.
You can watch me demonstrate layering techniques in this short video:
OKAY! Let's bring some color to our Painting!! 
  • Start in the back with the sky
  • You already have your values 
  • Adjust your edges as you go
  • Add your foreground details and brushstrokes last

Learn about Values! Step by Step! Class #2

The Magic of Values in the Acrylic Landscape. Class #2
by Karen Ilari 


Develop your 5 Value Block In to Full Value


After our last class, we now have our large shapes of solid value in the right locations on our canvas. Yours should look something like this:

Now we want to further develop this sketch. How do I do that?!
Keep these things in mind:
  • All you need to do is break the LARGE shapes into SMALLER shapes.
  • Maintain the same overall VALUE in the area.
  • Just refine the shapes to more accurately match your reference. 
  • Think about SIZE, SHAPE, and PLACEMENT of each spot of value
  • Still using the same 1/2" flat brush.
  • Don't think about DETAIL, just breaking down the large shapes into smaller ones.
  •  Pay attention to the EDGES of your shapes. Should they be soft and blended or hard and crisp?
  • Take your time. Study what you really see in your reference. Don't assume anything. Really look at what is there paint it the way you see it.
This is how you TRAIN YOUR EYE to focus on value. It takes practice. Just knowing what you should do is no substitute for picking up your brush and laying down the paint. You need to develop those pathways from your eye to your mind to your hand until it feels like the mind is no longer even involved. Straight from your eye to your hand. It becomes automatic. But ONLY after you spend the time practicing your craft!

EDGES           
What does that mean?
Instead of thinking about the image you are painting as THINGS - trees, bushes, flowers. I want you to think of them as SHAPES with a certain VALUE, COLOR, EDGE, SIZE and PLACEMENT.

We've been learning about Value, and the others are pretty easy to understand. But what do I mean by EDGES? Let's take a minute to talk about this some more: Here is a close up from our reference photo:
Now. SQUINT YOUR EYES as you look at this.
Do you see the hard edge between the tree trunk and the background field? You can clearly SEE the edge. It is crisp and distinct.
Look at the foliage in the tree. Do you see how these edges are less distinct - the blend together more.
Look at the edges of the shadow of the trunk lying on the ground. Do you see how the edges of this shape are softer? Compare that edge to the bottom edge of the trunk just above it
Here is another example:
Look at the edges of the shapes in the background mountain. They are soft and blended. Do you see as you come forward in space, your edges become more distinct, but not as sharp as the edges in our foreground.

Now. That is what we see in our reference photo. 
Now we have to USE this reference and EDIT it to tell OUR STORY. 
Edges can be a powerful tool to:
  • create emphasis in your focal point with crisp, distinct edges
  • lead the eye through your painting with strategically placed crisp edges
  • de-emphasize a less important area by softening the edges
  • create a stronger sense of distance by softening edges even more than you see
  • Create subtle gradations of value and color by softening the edges between the shapes
  • describe the texture of an object- how hard or soft it is. Hard objects create crisper edges
So you can have a strong change in VALUE from one shape to the next. But you will get a different effect depending on whether that shape has a SOFT EDGE or a :HARD EDGE. 

Exercise #1
EDGES
Supplies: Mars Black and Titanium White Heavy Body Acrylic Paint.
                flat synthetic brush - about 1/2" wide
                water container, paper towels, palette
                watercolor paper                   

How do I do get a soft edge with Acrylics?
Using your watercolor paper, and your black and white paint. Let's practice some edges
The key to soft or blended edges in acrylics is understanding how much wet time you have before the paint dries. This is something you will get a feel for the more you paint. 
In general: 
  • Work Quickly, in small areas
  • For Larger areas - like a sky - Use larger brushes.
  • Lay down a shape, adjust the edges right away.
  • Be sure to work over at least one layer of paint - your block in
  • Use a good quantity of paint
  • Rinse your brush often 
  • Use a light touch
  • Adjust the wetness of your brush with a paper towel
So on your paper. Make some rectangles of different shapes like this. Let them dry. 
Now lets make some blended edges between these. There are three  ways:
One Value (or color)
1.  Lay down a shape of just one value - blend the edge RIGHT AWAY 
2.  Rinse your brush thoroughly. Blot on a paper towel.
3.  Use a scrubbing motion from the dry side into the wet side to soften the edge

 Two Values (or colors)
1.  Mix up the two values that you want to blend
2.  Paint in your two shapes. If the shapes are large, just do a smaller section at a time.
2.  QUICKLY rinse your brush and blot it to damp.
3. Use a sweeping motion to blend the still wet patches

Three Values (or colors) 
1. Mix up a shade between the two values you are trying to blend
2. Lay it down on the blending area
3. Rinse your brush thoroughly. Blot to damp. 
4. Use the scrubbing motion as before to blend each side of the new patch.

In all methods. Finish off by cleaning your brush thoroughly, blotting to damp, and very lightly sweeping across the area to blend. Wiping often on a towel to remove excess paint picked up.

So now let's practice those different edges as we finish our full value block in of our painting
 When you are done, you should have something like this:
  You may notice that I've made further refinements to my 5 value block in:
  • The field behind the tree is lighter to add more contrast to the dark tree form and draw more attention to my focal point.
  • The shape of the tree and shadow have been developed and refined.
  • The value shift between the field and wildflowers have been blended and minimized.
These are the kind of changes you make as you spend more time with your reference, and with the way the image is developing on the canvas. You are adding your own interpretation. What feels and looks right to you. Everyone see and paints differently. You can't help your own individual style coming through. It's not something you decide on or make up. It's just what happens after you paint for a while.
