Johanna Logan Art Demonstration

 

 Thursday 24th October 2024 - Still Life in Oils

 


Jo starts the demo by showing us a photograph on her iPad of an arrangement of leaves and wild anenomes which she had foraged in the woods

 


We see the underpainting in oils on paper that Jo did beforehand at home.

 


Jo begins by looking for dark neutrals in the picture. She then mixes burnt umber with ultramine blue to make a dark grey which is applied to the darker area of the vase. White is added to the grey mix for lighter areas.

 


Here you can see Jo with her colour palette. She uses earth colours, burnt and raw sienna as well as burnt and raw umber. Her blues are ultramarine and cerulean. The red is cadmium red. White is a mixing white. Viridian is used as a green base adding colours to make a different green. Jo makes up an artist's medium using linseed oil and turps.

 


Viridian is used as a base for mixing greens for the leaves. A darker green colour can be produced by mixing in cadmium red. This colour is applied with a filbert brush to the darker areas under the leaves. Raw sienna is added to paint the areas between the leaves. The leaves on the left hand side are painted a cooler green by adding blue to the green mix.

 


More raw sienna is applied to the leaves. Cadmium yellow light is added to the green mix to leaves then cadmium red to calm down the green mix. More yellow and mixing white is used for lightening the green and used on lighter areas.

Shadows of foliage on the right hand side of the wall are painted in neutral colours plus brown. The foreground is then painted.


The wall shadow on the right hand side is painted. Thinning the neutral mix with  artists medium, Jo paints the background. Using a mixture of burnt sienna, burnt umber and raw sienna a rough outline of the ferns at the top are painted. A mix of terra vert, earth colours and ultramarine is applied to the fronds of the ferns using a rigger brush. Jo tells us that viridian is her choice of green as it can produce a variety of greens when mixed with other colours.

 

 
Anenomes are suggested using the end of a brush. They are then worked on with a mix of grey and white.

 
Darker areas around the anenomes are painted. 

 


The ivy is defined, sharpening the edges of the leaves with a lighter colour, a mix of raw sienna, blue and burnt sienna mix.  Using this same mix plus yellow, the leaves in the centre of the painting are painted.
 


Areas between the leaves are touched up and leaves defined. Viridien and red are mixed to add more detail to leaves at the right hand side.
 


Details to the leaves are added to the left hand side, then more work on central areas. Light and dark areas of vase are blended. More shadow is added to the top right then the left hand side.

 

Unfortunately, time caught up with us at this point but Jo will send a photo of the completed painted which will appear here shortly.
