A wide angle lens is an excellent choice for environmental portraiture.Study for a Portrait 1952 dates from a crucial point in Bacon’s engagement with portraiture, and is likely to have been made in the studio of the artist Rodrigo Moynihan at the Royal College of Art in London (see Wilson 2008, p.98). Assuming you're using a prosumer DSLR camera, it's best to stick to the 35mm -> 80mm range.Lens distortion, or optical distortion, occurs in many camera lenses of various focal length – even expensive, professional lenses.Both Manny and Pierre used the distortions to their advantage by shooting from. Generally speaking it's best to avoid using a wide angle lens or the wide end of the focal range, otherwise you could end up with distorted portraits. Avoid distortion when taking portraits using wide angle lenses.
Pincushion DistortionPincushion distortion is when vertical and horizontal lines appear to pinch into the center point of an image.Pincushion distortion is quite common in zoom lenses, particularly telephotos such as a 70-200mm.Pincushion distortion is most apparent at the telephoto end of the focal length (for example, 200mm). Fisheye lenses actually make creative use of barrel distortion.When you photograph an image with a fisheye, you are looking for that distinctive distorted look – it’s not something to avoid or overcome.Fisheyes capture extreme wide angles of view and barrel distortion is inevitable in these images – the distorted look of fisheye lenses is what gives them their charm and wow factor. Get too close to a person with a wide-angle lens like a 24mm and it can really warp their appearance – something to be very aware of when photographing people with wide-angle lenses.Fisheye lenses are specialist, ultra-wide lenses – they vary in focal lengths and you can find 8mm fisheyes and 15mm fisheyes.
Unlike optical distortion, it’s not related to the lens you are using.Perspective distortion is all about the subject you are photographing and the distance and angle you are photographing it from.Get too close to an object, person or building with any lens and it will distort. Some older 18-35mm wide-angle zooms, for example, show mustache distortion at its worst.Perspective distortion is different to optical distortion. No wonder they call it complex, hey?Mustache distortion is most apparent in older lenses. It is probably the hardest type of optical distortion to ‘deal’ with.This is because straight lines close to the center curve towards the middle of the frame, while straight lines further out curve towards the edge of the frame. Mustache DistortionMustache – also called wavy or complex distortion – only occurs in some lenses and is a combination of the barrel and pincushion effects.
The same effect can be seen easily with lampposts or tall trees.To correct linear perspective distortions in post-processing, you can use the tools built into Adobe Photoshop, Lightroom, and other software. The most obvious occurrence is pointing up at a building or down a street of tall buildings and the buildings, instead of being vertical, appear to lean inwards. Also, in certain circumstances, if you went far enough to remove the distortion, your subject might become too small.Perspective distortion is also nuanced – there are lots of different kinds.Linear perspective distortion occurs when you point the camera up or sharply down at an object.
Avoid extreme wide-angle lenses – The wider the lens – for example, a 15mm prime – the greater the distortion. For instance, landscape photographers often use this distortion to privilege the foreground – say, the edge of a lake – to better show off the mountains and sky in the distance.We’ve seen how some of the unacceptable results of lens distortion can be achieved or reduced by choice of lens and also by how far you stand from the subject.With that in mind, here are some quick tips for preventing distortion: We might just accept that that’s perspective and it just means we’re closer to the foreground.However, it can also give an inaccurate feel to the photograph where things just don’t look right.As usual, though, you can turn the error into a useful effect. In most images, the foreground looks much too big for the background.
Use a nifty fifty – 50mm lenses are often seen as ‘all round’ lenses. Stand back and add space around your group – you can always crop in later when editing if needed. Get too close to the group and the distortion makes the people standing at each end look much wider! So be aware of your composition. But others, such as using a wide-angle lens to take a group photo of a row of people, must be considered carefully. Be aware of your composition – There are many situations where some distortion can be acceptable or even something you aim for. Don’t get too close – In many lenses this will increase the optical distortion, and in all lenses, it will increase the chance of perspective distortion.
Distorted Portraiture How To Fix Image
There are several options to allow you to do this, all within the Lens Corrections and Transform tabs.First of all, you can try to load up the automatic profile corrections, which are based on the specific lens you are using.This will automatically correct both distortion and vignetting caused by your lens – however, it’s certainly not a catch-all solution.Sometimes you’ll need to attempt to correct the distortion manually, but it’s worth trying profile corrections first. You will see that a 50mm lens has virtually no optical distortion.How do you fix a wide-angle distortion or pincushion distortion where your photo is warped in some way?Thankfully, Adobe Lightroom, Photoshop, Exposure X6, Luminar AI and various other popular image editors make distortion correction simple here in 2021.Here’s how to fix image distortion using two of the most common post-processing apps: Lens Distortion Correction with LightroomYou can fix lens distortion with Lightroom really effectively. You will of course just need the space to step back if your subject is large.
Here you will find all the options you need to correct and fine-tune lens distortion.You can start off by trying the automatic options within the Transform tab.Click on Auto – it will give you a good all-round lens distortion correction. These processes work in conjunction with the Enable Profile Correction option.First, find the Transform tab. So if you’re dealing with really visible optical distortion or perspective distortion, you will need to correct this manually.More nuanced correction of distortion in Lightroom definitely takes a little more effort – but it’s well worth getting to grips with. From here, a drop-down list will appear – simply choose the lens you used for your photograph.However, though this will correct some optical distortion, it will be based on the lens – not the image.
Auto – Both vertical and horizontal distortions are corrected. Level – Corrects any horizontal distortions. Vertical – Rights vertical distortion in the image.
