Ever drawn from a photo and thought something’s not quite right but you can’t put your finger on it?
And here’s the thing, you copied the photo perfectly well, so you know it’s accurate.
There’s a good chance it’s lens distortion messing with your proportions.
It’s one of those sneaky problems artists don’t notice until it’s too late. The dog’s nose is too big, the legs too short, or the whole body looks stretched. We’ve all been there.
The truth is, the camera lies and doesn’t see the way you do. Lenses bend reality, and if you don’t spot it, you’ll end up copying the distortion along with the detail.
Let’s look at why it happens and how to fix it.
What Lens Distortion Does to Your Drawings
Essentially, lens distortion changes the way shapes and proportions appear in a photograph. It isn’t always obvious, but it can make parts of your subject look bigger, smaller, or oddly shaped compared to real life.
Wide-angle lenses exaggerate anything close to the camera, making noses, paws, or beaks look oversized. At the same time, features further away appear smaller than they really are.
Telephoto lenses have the opposite effect. They flatten perspective, so the distance between features seems shorter and the whole subject can look squashed.
Neither of these views is “wrong” for photography, but when you translate them directly into a drawing, you’re recording the camera’s version of reality, not what you’d see with your own eyes.
The lens fools your brain into accepting the distortion as truth.
How to Spot Lens Distortion Before You Start Drawing
Before you put pencil to paper, take a few minutes to study your reference photo. A quick check can save hours of correcting or God forbid, starting again.
Look for exaggerated features
Does something seem unusually large or small? I draw animals mostly so I check for things such as the size of the nose, ears, or paws compared to the rest of the body. If they look out of proportion, the lens might be to blame.
Check for stretching or squeezing
Straight lines in the real world should look straight in your photo. If you see curves in places that should be straight, that’s a sign of barrel distortion (common in wide lenses) or pincushion distortion (more common in telephoto).
Watch the edges
Subjects placed toward the edges of the frame can appear stretched or distorted. This happens because lenses bend light more near the edges than in the center.
Check the verticals
I always look at vertical lines like tree trunks, poles, or building edges. If they lean or bow, you’re seeing perspective shift or lens bending that you might want to correct before you start.
How to Correct Lens Distortion in Your Drawings
You can’t change the reference photo easily, but you can correct for distortion before you commit to your final drawing.
Use multiple references
If possible, find other photos of the same subject taken from different angles or distances. This will help you judge the true proportions and avoid relying on a single distorted image.
Straighten your lines
If verticals or horizontals are bending, lightly redraw them so they’re straight. This can instantly fix the feeling of a warped scene.
Adjust proportions early
Make small corrections in your rough sketch. If one area looks stretched, compress it slightly; if another looks squashed, give it more space. These tiny tweaks can make a big difference.
Step back and compare
Take regular breaks and compare your drawing to what you know the subject should look like. Even a short pause can help you see distortions you’ve been missing. This is an important tip. Be focused in short bursts and then step back.
Measure with dividers
Using a grid can sometimes fool you into repeating the wrong proportions exactly. Instead, use dividers to measure and compare key features in the photo. This will help you spot exaggerated or shrunken areas before they end up in your drawing.
Quick Fixes for Photo Editing Your References
Before I knew my way around photo editors, I used to do this the hard way. I’d photocopy my photos at different sizes, get out the scissors, and literally cut and paste elements together until I had a better composition. It worked, but it was fiddly, crude, and messy.
These days, you can do the same thing in minutes with free tools like Photopea. It works in your browser, feels a lot like Photoshop, and doesn’t cost a penny.
Here’s how you can use it to improve your reference photos:
- Resize individual elements
If something in your photo feels too big or too small because of distortion, select it with the lasso tool, copy it to a new layer, and resize it until it looks natural. - Combine parts from different photos
Open both images, select the part you want from one photo, and paste it into the other. This is perfect for swapping heads, tails, or repositioning a leg to improve the pose. - Straighten verticals and horizontals
Use the Transform tool (Edit → Free Transform) to nudge and straighten leaning poles, tree trunks, or horizon lines before they make it into your drawing. - Crop and reframe
Don’t draw around distracting background elements. Crop in to focus on the subject and set a stronger composition. - Check proportions visually
Temporarily drop a grid over your image (View → Show → Grid) to compare relative sizes. You don’t have to copy the grid in your drawing, but it can help you spot distorted areas worth fixing.
If you’re not sure how to do any of these steps, asking ChatGPT to walk you through Photopea is far more helpful than trawling through Google or YouTube tutorials, you can get tailored instructions instantly.
Drawing From Photos: Final Thoughts
Lens distortion is not the enemy, it is just something to be aware of. Once you know how to spot it and correct it, you can use photo references with much more confidence. The goal is not to copy a photograph perfectly but to capture the subject in a way that feels true to life.
Improving your technical skills is only one side of the art journey. If you also want to learn how to turn those drawings into income, my book Selling Art Made Simple will walk you through exactly how I have done it for over twenty years.
It is a practical, straight-talking guide for artists who are ready to share their work with the world and get paid for it.
