7 Exams to Examine the Accuracy of Your Portray

On this submit, I’ll share a number of the exams you should utilize to examine the accuracy of your work or to diagnose errors. I’ll use my current portray, Elora and White Roses (proven beneath), to display my factors.

Why These Exams Are Vital and When to Use Them
In fact, the important thing profit of those exams is to provide extra correct and plausible work. Nevertheless it’s additionally about honing your judgment as an artist. It’s unimaginable to hone your judgment should you’re naive to your personal shortcomings or errors.
You need to use these exams at any level all through the portray course of. I discover them notably helpful for the next:
- At first of a portray once you’re establishing the muse, particularly for advanced topics.
- To be sure to’re heading in the right direction halfway by way of a portray.
- Upon getting accomplished a portray to confirm your accuracy.
- When you have to diagnose a mistake or downside.
1. Squint Check
Squint at your portray and the topic and search for any obtrusive 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 features of your work, notably in relation to worth (how gentle or darkish your colours are) and the most important shapes.


2. Thumbnail Check
Take a look at a thumbnail photograph of your portray. If it appears to be like real looking, that’s an excellent signal you bought the basics proper. It’s also possible to 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 Examine Your Portray to the Reference Picture
Examine a photograph of your portray to the reference photograph. I take advantage of a collage app on my telephone, however any enhancing software program akin to Photoshop or Canva will do (Canva is free and beginner-friendly). This exams for problems with scale, perspective, and drawing. Portrait painters would discover this take a look at notably helpful.

4. Grid and Key Measurements Check
Place a three-by-three grid over a photograph of your portray and your reference photograph. You would additionally place vertical and horizontal strains that undergo the center. Use the gridlines and intersections as reference factors to take key measurements with which you’ll take a look at the accuracy of your drawing, scale, and perspective. I usually solely do that for advanced topics involving individuals, 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 important 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 elements 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 beneath and their positions in relation to the grid.

I additionally used the gridlines to examine key strains 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 correct.

5. Grayscale Check
Grayscale a photograph of your portray. It will mean you can clearly see the worth construction (how gentle 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 beneath a grayscale of my Elora portray and the reference photograph. A number of key observations:
- My portray is extra compressed when it comes to 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 might have labored properly with the brilliant, overcast sky as a backdrop.
- My portray has much less worth distinction within the background (see the bushes on the again and the sky). I made up for this by utilizing refined adjustments in hue and visual brushwork.


6. Colour Checker
Use Photoshop or another enhancing software program to examine a selected shade within the reference photograph. For instance, say I’m not sure in regards to the shade of Elora’s proper arm in shadow. I can use a shade checker to examine the colour when it comes to hue, saturation, and worth. I can use this info to confirm and make extra knowledgeable selections. Take into account, I don’t do that usually. I want to rely alone judgment first. That is extra of a backup possibility if all else fails.

7. Destructive House Check
Examine an space of adverse area within the portray to that of the reference photograph. Destructive area being the world between objects and issues. For instance, I might confirm the accuracy of my drawing of Elora by trying on the adverse area surrounding her and the shapes that area varieties. If the adverse area has a unique form to that of the reference photograph, then one thing is mistaken with my drawing.

A Phrase of Warning
Don’t get caught up making an attempt to confirm each determination you make in a portray. That might sap the enjoyment out of portray.
Additionally, there are occasions when it’s OK to be mistaken. Maybe you need to exaggerate or restrain a sure element. Or maybe the error is insignificant and never value fixing.
Reserve these exams for important and elementary features of your portray. Issues that basically push the needle. For instance, should you’re portray a portrait, it’s important that you just get the eyes and nostril proper. Nevertheless it’s much less essential to get the precise format of the hair or the precise pores and skin tones.
