Though it appears like a extremely technical time period, ‘reverse engineering’ is one thing you’ve carried out many instances. Any time you’ve requested questions like “What digicam did you’re taking that with?”, “What settings did you utilize?” or “The place was this taken?”, you’ve been attempting to reverse engineer {a photograph}.

lake how to reverse engineer photos

We’ve all checked out a photograph and tried to determine the way it was created. I do it day by day. Whether or not you’re acutely aware of it or not, whenever you see a photograph you admire you attempt to analyze it. You’re asking, “How do I take images like that?”

The reality is, in case you ask the photographer about their digicam or settings you’re asking the incorrect questions. By all means, ask questions. In spite of everything, that’s how we be taught. However you may as well be taught loads from finding out a picture – if you understand what to search for. When you’ll be able to visually deconstruct a picture, you’re one cease nearer to having the ability to create one thing related.

This isn’t a lesson in plagiarism. It’s merely a method to be taught from different photographers whose work you admire. No profitable artist could be the place they’re immediately with out studying from the works of others they appear as much as.

Gentle and Shadow

An important photographic lesson I ever realized is that it’s all in regards to the mild. Reverse-engineering images is not any totally different. Analyzing the sunshine in a picture is the only and only method to learn the way a photograph was made.

If you have a look at the picture, ask your self a couple of questions.

  • Which course is the sunshine coming from?
  • Is there multiple mild supply?
  • Is the sunshine arduous or smooth?
  • Is there mirrored mild within the photograph?
  • What in regards to the colour temperature? Is it heat or cool?

Typically the solutions will likely be apparent. Typically they’ll be unimaginable to reply. However the extra typically you ask them, the higher you’ll get at answering them.

In case you’re taking a look at a panorama photograph, you’ll be able to nearly at all times assume there’s just one mild supply – the solar. However that doesn’t imply you’ll be able to’t deconstruct the sunshine. The course, hardness and temperature of the sunshine will inform you a large number in regards to the situations the photograph was taken in. Though lovely panorama lighting isn’t as technical as portrait or product lighting, you’ll be able to nonetheless be taught loads from analyzing it.

The solar putting this panorama, together with the nice and cozy mild on the best aspect of the picture, clearly present the place the sunshine is coming from.

In case you’re reverse-engineering a portrait, it’s extra more likely to have multiple mild supply, in addition to mirrored mild. When a photographer begins balancing a number of mild sources, reverse-engineering a photograph can turn out to be harder. However there are nonetheless methods to investigate the sunshine if you understand what to search for.

Begin by asking your self, “The place are the shadows?” It could appear a bit backwards, however probably the greatest methods to investigate mild is to have a look at the darker components of the picture. The place is there no mild? Do you see any arduous shadows? Are there areas the place you’ll be able to see the sunshine dropping off steadily? Finding out the shadows will inform you in regards to the course of the sunshine in addition to how giant it’s relative to the topic.

The illuminated fur across the exterior of the bear present that this picture was backlit. And its shadow on the bottom reveals the precise course the sunshine was coming from.

Deciphering {a photograph}’s mild turns into harder because the lighting will get extra complicated. As extra mild sources or reflectors are added, the shadows turn out to be much less apparent. If the shadows are very mild or non-existent, it possible means both the sunshine could be very diffuse and bouncing in every single place, or there are a number of mild sources.

In case you’re fortunate, you’ll be able to typically see precisely what mild supply was utilized by in search of reflections. Take a look at the eyes, glasses, home windows, water surfaces, and something that displays mild. Typically you’ll be able to see an ideal reflection of the sunshine supply, however on the very least you’ll be capable of see its course.

The smooth mild on the topic, mixed with the reflection in her glasses, present the window as the sunshine supply. The very darkish shadows inform us there are not any different mild sources.

Gear and Settings

In lots of circumstances, you don’t have to ask what gear or settings had been used to create a photograph. With follow, you’ll be able to be taught to guesstimate the technical particulars corresponding to focal size, aperture and shutter velocity.

Determining what focal size was used isn’t too troublesome as soon as you know the way focal size impacts a photograph. As a basic rule, the shorter the focal size (wider angle), the extra distortion you’ll see and the extra of a scene will match within the body. Because the focal size will get longer (regular or telephoto), you’ll see extra compression within the picture and fewer of the scene within the body.

Solely a really wide-angle lens can seize every little thing in a scene like this from the bottom to the sky. The lens distortion makes nearer objects like this automotive look a lot larger.

Whereas this received’t inform you the precise focal size used, it provides you with a ballpark determine. With follow, you’ll be capable of inform if a photograph was taken with a wide-angle (85mm) lens. The precise quantity doesn’t matter. What does matter is getting a tough thought the place your focal size must be to create the identical look.

As with focal size, you’ll be able to determine roughly what aperture was utilized by understanding the way it impacts a picture. Because the lens aperture opens and closes, the depth-of-field (DOF) of the picture adjustments. The broader the aperture (smaller f-number), the narrower the DOF.

Once more, the precise quantity doesn’t matter. What issues is knowing how aperture impacts DOF and tips on how to interpret the DOF of a photograph. If the picture is sharp and in focus from the foreground proper via to the background, a smaller aperture (f/11-22) has in all probability been used. If every little thing however the topic is smooth and out of focus, a bigger aperture (f/1.4-5.6) has in all probability been used. If the DOF is someplace in between, the aperture might be round f5.6-11.

Lastly, these rules can be utilized to shutter velocity. You in all probability know that shutter velocity impacts the way in which motion seems in a picture. If objects you’d anticipate to see transferring are frozen nonetheless, you understand a quicker shutter velocity was used. If there’s some movement blur within the picture, you understand the shutter velocity was slower.

You possibly can see {that a} longer shutter velocity has been used right here to create the milky water impact, frequent with long-exposure images.

With a panorama photograph, any time you see silky-smooth water or clouds frequent with lengthy exposures you understand it has a shutter velocity of a minimum of a couple of seconds. In case you’re seeing some motion, it’s extra more likely to be lower than one second. To freeze motion, you’d anticipate shutter speeds of a minimum of 1/100th of a second.

Very brief shutter speeds are required to seize transferring water, as on this seascape photograph.

If the photograph doesn’t embrace any transferring objects, it’s far more troublesome to determine the shutter velocity used. But when there’s no motion then shutter velocity doesn’t actually matter. It simply must be quick sufficient to keep away from any blur brought on by digicam motion to make sure a pointy picture.

Put up-Processing

Reverse-engineering the post-production that’s been utilized to a picture is the trickiest half. There’s nearly no restrict to what will be carried out in Photoshop immediately, which makes it troublesome to determine how a photograph has been processed.

You may get a tough thought of how a lot post-processing has been utilized by trying on the photograph. Does it look lifelike? Do the colours and tones seem the way in which you’d anticipate in actual life? Is the entire picture nicely uncovered from the darkest shadows to the brightest highlights? Are the sunshine and shadows constant throughout the picture as you’d anticipate? Do the folks look actual, or impossibly good?

Asking these sorts of questions will assist you understand what to search for. It’s simple to take a look at the picture as an entire and get pissed off attempting to investigate it. As you break it down and have a look at the person particulars of a photograph, it turns into simpler to see the edits which have been utilized.

I’ll admit this isn’t precisely my sturdy swimsuit, being colorblind. Choosing out the colour grading or results which have been utilized isn’t simple for me. However with follow I’ve turn out to be a lot better. And if I can do it, so are you able to.

You possibly can see by trying on the church that further heat has been added in post-production to emphasise the nice and cozy late afternoon solar.

Remember that photographers and retouchers which are extremely expert in Photoshop, are excellent at making their photographs look pure and unedited. Simply because a picture appears actual doesn’t imply it’s. A photograph that’s been edited by a Photoshop ninja will likely be very troublesome to reverse-engineer.

Exif Information

When all else fails, and also you desperately need to know the settings used to take a photograph, you might be able to entry the picture’s exif knowledge. When a digital {photograph} is created, a bunch of knowledge is embedded into the file. This contains focal size, shutter velocity, aperture, digicam mannequin, and infrequently a bunch of different info.

A photograph’s exif knowledge is usually stripped out by the photographer or the web site it’s uploaded to. But when it hasn’t been stripped, you’ll be able to simply entry the information by both:

  • downloading the picture and studying the information in your pc
  • utilizing one of many many web sites that can analyze a photograph’s exif knowledge for you.

Some web sites, corresponding to exifdata.com, may even analyze a photograph from the picture’s URL.

The shadow of the tree clearly reveals the course of the solar, whereas the sunshine reflecting off the concrete has crammed within the shadows on the topic.

Use Your New Powers Correctly

Now that you know the way to reverse-engineer a photograph, go and follow. The extra you do it, the better it would turn out to be. As a photographer, having the ability to analyze and deconstruct a photograph is an extremely beneficial ability. You possibly can be taught an amazing quantity from different photographers by doing this.

However once more, this isn’t a lesson in plagiarism. It’s about rising as a photographer by studying from different folks’s images, not recreating or cloning them.

Now, go and discover some images you like and deconstruct them utilizing your new-found powers.
