Checking values in acrylic paintings

I’ve been working on a harbor painting for a while now, on and off. It started as a realistic painting, and then it turned into a more contemporary one. Kind of in the middle of that transition I decided I would portray the scene half in the sun, and half in the shade. That’s when I started having value problems. 

Picture 1 with color
I was using warmer colors in the sunny areas, and cooler ones in the shade, but I soon realized that some warm hues have a darker value than cool ones, and focusing on temperature instead of value can really spoil all you are trying to do.
Every painter knows the squinting technique to see values, but squinting has its limitations. What helps me a lot is using the “desaturation tool". Here is how it works: I take a digital photo of the artwork, I download it into my computer, and I desaturate it using Photoshop (many other image editing software can do it too). Then I really see values.

Picture 1 desaturated
What I saw in my desaturated painting was a lot of mid-tone values. It did not have the sun vs. shade look that I was trying to achieve.
I took notes of needed corrections, and went back to the easel.
After few changes, I took another photo, and desaturated again. I’ll work more on it, but this is where I am now, you can see it below.




It does not seem like a lot of difference, but I did lighten quite a few areas.









What do you think, am I going on the right direction?
Do you know/use a different technique to check values?


Thanks for visiting,
Love,
Robie

    YES! You are definitely going in the right direction!! It's great to see another artist using photoshop... I commonly print black and white reference for value checks. LOVE to see and read about your process, very glad to discover your blog!!

    Thanks Diane, this is most encouraging. I'm an admirer of your art, and I love to read your posts. I'll keep your advice in mind, and aim at painting miles of canvas with a black and white reference, can't wait to see what happens on the journey to find my style and broad my skills. I'm sure it will be fun! :)

    Robie, that is a great technique for checking your values. Do you have a grey scale, gradation card? I have a few and that can help so you can see just where the dark value is on that card. I think you are definitely on the right track it is really amazing how much adding the dark and lights in can make a dramatic difference with just a little tweaking. I really love this painting, the colors are great:) Can't wait to see it progress! And thanks for stopping by my blog, loved reading your comments:)

    I'm so glad you guys think I'm heading on the right direction, it gave me some needed motivation! I'm happy you can see the improvement in the painting. Thanks!
    Carrie: I do have a gray scale gradation card. I probably use it too sparingly, but I have to admit that it can really help checking values. I've been thinking I should use it more, I guess it's time to make thoughts into action. :)

    Suzanne, I started only recently using photoshop for desaturating, and I love how it simplifies the process of value comparison.
    I really appreciate you taking the time to stop by and leave a nice comment!

Winter is Coming - Portrait, Acrylic on Canvas

Image
"Winter Is Coming" 12"x16" Acrylic on Canvas Available   I am really pleased with how this painting came out.  And to think that I used to be very intimidated by painting people, now I can do portraits that really resemble the model, woohoo!  :) I used a canvas that had an abstract pattern already painted on it, with the idea of covering the pattern in most areas, leaving only a few hints of it here and there. However, when I started the new painting, I really liked the pattern background and how it was peaking through everywhere, so I kept it visible as part of the composition. The model was wearing a warm scarf, and it made me smile when shortly after we got our first big snow of the year, she must have known that winter was coming, and coming soon. :)

Cane Corso, the Italian Mastiff - acrylic dog painting

Image
"Ettore" 9" x 12"  Acrylic on canvas panel Ettore is a very black dog that belongs to my family in Italy. I hear stories about this smart and friendly puppy all the time I call home, from what they tell me he’s such a handful! My family always had German Shephards, and this is the first “different” dog in the household, his breed is Cane Corso, an Italian tipe of Mastiff.  I asked for some pictures of him and he’s so cute that I couldn’t resist painting him. The fun part is that I did not use any black paint. I’m curious to hear what my family thinks about this portrait, did I get the personality of a dog I never met?   We do not see things as they are.  We see them as we are. Talmud

Japanese Maple Tree - Acrylic Landscape Painting

Image
Japanese Maple Tree 16"x20" (40.6 cm x 50.8 cm) Acrylic on stretched canvas, framed In front of our first home there was a Japanese Maple Tree. We bought the house in November, and I had no idea that the naked twisty tree in the front yard could get so pretty and colorful (not many Japanese Maples in Italy, where I was coming from). Spring is always a delight for me, and the first spring in the new house, I was so excited to discover what could be sprouting in the flower beds, what beautiful treasures were planted by strangers that lived there before us. There were tulips, daffodils, irises, but what really elated my heart was the little tree with the star shaped red leaves. A true delight. When, more recently, I saw a picture of the Japanese Maple Tree from the Portland's Japanese garden, with those beautifully bent branches and bright leaves, it brought back cheerful memories, and renewed my sense of wonder for this amazing plant. I just had to paint
