On this put up, I’ll share a few of the assessments you should use to verify the accuracy of your work or to diagnose errors. I’ll use my current portray, Elora and White Roses (proven under), to exhibit my factors.

Why These Exams Are Vital and When to Use Them
In fact, the important thing profit of those assessments is to supply extra correct and plausible work. But it surely’s additionally about honing your judgment as an artist. It’s not possible to hone your judgment if you happen to’re naive to your personal shortcomings or errors.
You need to use these assessments at any level all through the portray course of. I discover them notably helpful for the next:
- At the beginning of a portray while you’re establishing the inspiration, particularly for advanced topics.
- To ensure you’re heading in the right direction halfway by means of a portray.
- After getting accomplished a portray to confirm your accuracy.
- When you have to diagnose a mistake or downside.
1. Squint Take a look at
Squint at your portray and the topic and search for any evident points or irregularities. Squinting reduces the “noise” of what you see and makes every little thing seem hazy and a contact darker. It’s an efficient take a look at for the big-picture facets of your work, notably in relation to worth (how mild or darkish your colours are) and the main shapes.
2. Thumbnail Take a look at
Have a look at a thumbnail photograph of your portray. If it appears real looking, that’s a very good signal you bought the basics proper. You too can evaluate a thumbnail of your portray to a thumbnail of the reference photograph to identify any big-picture irregularities.
3. Use of Collage App to Evaluate Your Portray to the Reference Picture
Evaluate a photograph of your portray to the reference photograph. I exploit a collage app on my cellphone, however any enhancing software program reminiscent of Photoshop or Canva will do (Canva is free and beginner-friendly). This assessments for problems with scale, perspective, and drawing. Portrait painters would discover this take a look at notably helpful.

4. Grid and Key Measurements Take a look at
Place a three-by-three grid over a photograph of your portray and your reference photograph. You may additionally place vertical and horizontal traces that undergo the center. Use the gridlines and intersections as reference factors to take key measurements with which you’ll be able to take a look at the accuracy of your drawing, scale, and perspective. I sometimes solely do that for advanced topics involving folks, animals, or structure.
I used grids and key measurements in Elora and White Roses to make sure my drawing of Elora was heading in the right direction. It was crucial that I bought her scale, form, and proportions proper. On a number of events, I bought out a ruler and measured the precise distance between components of Elora and the closest gridlines. I then needed to evaluate this to the relative distance within the reference photograph. Tedious work, however I needed to get this one proper.
I used to be notably centered on the areas circled under and their positions in relation to the grid.

I additionally used the gridlines to verify key traces and angles. For instance, to confirm the accuracy of Elora’s left arm, I mentally drew a line that prolonged from her arm to the closest grid line. If the road intersects the grid in the identical spot because the reference photograph, I do know all is true.

5. Grayscale Take a look at
Grayscale a photograph of your portray. This can will let you clearly see the worth construction (how mild or darkish all the colours are). You possibly can evaluate this to a grayscale of your reference photograph. Pay explicit consideration to the lightest lights, the darkest darks, and the association of sunshine and darkish shapes. See under a grayscale of my Elora portray and the reference photograph. A couple of key observations:
- My portray is extra compressed by way of worth. That’s, the lightest lights are a bit darker, and my darkest darks are a bit lighter than that of the reference photograph. That is by design, as I needed the portray to have a softer end with much less worth distinction.
- I’m lacking a darkish accent on the structure on the prime. This was additionally by design, as I didn’t need to draw consideration to this space and away from Elora. However, it may have labored properly with the intense, overcast sky as a backdrop.
- My portray has much less worth distinction within the background (see the timber on the again and the sky). I made up for this by utilizing delicate modifications in hue and visual brushwork.
6. Shade Checker
Use Photoshop or another enhancing software program to examine a specific shade within the reference photograph. For instance, say I’m not sure concerning the shade of Elora’s proper arm in shadow. I can use a shade checker to examine the colour by way of hue, saturation, and worth. I can use this info to confirm and make extra knowledgeable selections. Take into accout, I don’t do that usually. I desire to rely by myself judgment first. That is extra of a backup choice if all else fails.

7. Detrimental Area Take a look at
Evaluate an space of destructive area within the portray to that of the reference photograph. Detrimental area being the world between objects and issues. For instance, I may confirm the accuracy of my drawing of Elora by trying on the destructive area surrounding her and the shapes that area types. If the destructive area has a unique form to that of the reference photograph, then one thing is unsuitable with my drawing.

A Phrase of Warning
Don’t get caught up attempting to confirm each resolution you make in a portray. That might sap the enjoyment out of portray.
Additionally, there are occasions when it’s OK to be unsuitable. Maybe you need to exaggerate or restrain a sure element. Or maybe the error is insignificant and never value fixing.
Reserve these assessments for crucial and elementary facets of your portray. Issues that actually push the needle. For instance, if you happen to’re portray a portrait, it’s crucial that you simply get the eyes and nostril proper. But it surely’s much less vital to get the precise structure of the hair or the precise pores and skin tones.
