this was a fun exercise! I don’t really draw realism ever so it was good practice doing something with light source and depth.

I feel like I need more work on my values, but this was a good lesson moving forward. I like crosshatching, but I have to be careful not to over-work it! Getting the reflective light was key to a 3D effect! I got inspired to try drawing my dog because she is black and white.

I'm much more comfortable with the more simple line drawings, and I'm having fun experimenting with the mix of drawing and writing.  

I'm not yet good at the light and dark ranges to get the 3-D effect, but it's fun to practice.

I chose to represent the curious Citrus medica var. sarcodactylis, or the fingered citron. The mark making techniques I used are top row from left to right: outline, side shading, contour shading; mid row left to right: cross hatching , watercolor pencils, stippling; bottom row left to right: scribbling, blending, side shading. Perhaps my outline drawing would have been better without the horizontal lines. I think I need to work on the contour shading because there are areas where I overlap lines and get crosshatching. And my cross hatching is never just bidirectional rather diverse. I like how blending using a blending stump turned out. I was taught never to use this technique in school, but it is described as a technique used by scientific illustrators in the Guild Handbook of Scientific Illustration! So I guess I will be blending away in the future. As always, I am pleased with the Faber-Castell Albrecht Dürer Watercolor Pencils. If there is lack of detail it is due to the brush I used. All in all, an interesting exercise and I look forward to the next one!

Feeling somewhat more confident, but there is still a lot of practice in my future.  I am enjoying what I am learning in this course.

trying out the chiaroscuro technique, biggest challenge is getting the light parts to blend with dark parts.

I tried to draw an orchid in a pot using the markings to create some three-dimensionality.  It was not a roaring success, but that was before I listened to the chiaroscuro lesson, which made sense of the marks for me.  Now I can see how to work with the hatchings, scribbles, etc. to create depth.  BTW, can anyone tell me how to get my photos from my google phone transferred here?  I'm android, not Mac.

I think I picked some difficult subjects for this task, but I love my collection of seashells and want to be able to sketch them a lot better. I had difficulty trying to depict the texture lines while also trying to use the hatching and dots to depict shadows.      

I'm getting more familiar with putting marks on my pictures. However, I'm still not very good at creating the 3D vision.

I feel most comfortable with depiction texture and dimension, however, placement of shadows on the object and at the base of the object need more practice. Study of light source and effect on subject matter will help with my drawing and my photography skill understanding and application.

I am starting to feel more comfortable, and I'm certainly starting to see where all the different techniques can be applied. For the chiaroscuro lesson, I started with an apple. It was tricky because (in addition to me being a beginner) the apple had a variety of light and dark colors independent of the amount and direction of light falling on it. My wife suggested a lime, and I think that came out better. With the apple, I used a lot of contour hatching to try to get the indentation where the stem was that then shifted to the overall round shape of the apple. I tried to use some scribbling for the area around the light part on the bottom left of the apple. With the lime, I started with contour hatching, didn't like it, and then switched to regular/straight hatching. I figured if it worked to show the roundness of the ball, it could work for the lime as well. I liked the overall effect. I did some scribbling at the ends to get the hard/dark parts. I also tried a few circles to get the dimples, but that didn't seem to work very well. I used blending to obscure these...somewhat. I liked using hatching for the shadow, blending it, then adding more hatching. The blending helped smooth out the value shift from the darkest to the lightest parts of the shadows, and it softened the shadows' edges. For this birch round, I used a lot of contour hatching for the growth rings. I tried to overlay that with straight hatching to show the straight grooves left by the chainsaw. I used stippling for some holes I noticed in the outer dark layer of the wood. Scribbling seemed to work well to create the lenticels in the outer bark, and a little contour hatching helped with the curls of bark spiraling every-which-way around the edges. A little blending of denser hatching at the various dark spots on the surface seemed to help with the value difference in parts of the wood. I'm guessing these were formed by slight burning from the friction of the chainsaw when I cut the round.

• Trying to put in practice several `hatchings´ for this drawing, but when I took the draw´s photo, lights and shadows appears in the opposite distribution as you can appreciate.- I hope next time.

My Binoculars

I used a combination of stippling and hatching to attempt this value exercise. The most challenging thing for me is achieving the transitions between the values. This drawing probably would have been more successful if I had stuck with just stippling.

When I drew textured objects with light shadow contrast - I became so preoccupied with the form and light shadow that I forgot to try out the various types of shading

While in general it was easy to see where some of these techniques would be applied, I wouldn’t say it is really apparent to me when I am looking at things. How to decide which of the shading techniques to use in which situations isn’t particularly clear yet….but I am totally new at this! Rebekah Hamilton

I enjoyed practicing 3D techniques. Happy with my acorn by blending with the stump. The pear was not as convincing. I used contour hashmarking for the pear and crosshatching for the shadow. Tempted to finish with the stump but I was hoping to get an effective hashmark

I think I need to work on contrast and values the most at this point.  The chiarosco, while interesting, doesn't seem like it would be applied a whole lot to field sketching moving objects.  I realized while doing this squash that my lighting is not the most desirable.  I have three bulbs in cages that each act as their own light source and cast their own shadows.

I am starting to see better how to use different kinds of marks to make the kinds of textures that I see.  It was fun to scribble on the top of the bison head to make the curly hair. I don't think I was quite able to capture the texture of the lichen that I was going for.  Perhaps zooming in even more would be more effective. It is still difficult to get the values input correctly on something that is unevenly lit like the dog close-up at the bottom. I want to work on using the squint to get the values more accurate.  When I can get them right I feel like the image is most successful.
