HDR photgraphy is a well-liked photographic method which can be utilized to enhance the pictures you’re taking along with your iPhone and provides extra skilled trying outcomes. On this article we’ll take a nearer take a look at HDR pictures and look at what HDR is, uncover when and when to not use it, discover ways to use HDR in a frequent native digital camera app and introduce different photo apps which excel at HDR. By the tip of this text you need to be capable to exit and expertly take HDR iPhone pictures with superb outcomes.
HDR stands for Excessive Dynamic Vary and is a device which helps your smartphone’s digital camera tame the shadows and the highlights in photographic photographs – usually a drawback space for even devoted cameras.
A digital camera’s ‘dynamic range’ is its skill to seize the darkest and lightest parts of a scene in the identical shot. Sadly most cameras (even the costliest ones) can’t seize pure black and pure white and each shade inbetween in the identical shot. So when a digital camera (or a photographer) decides upon an publicity for a specific shot the digital camera often has to sacrifice one or each ends of the complete spectrum of darkish to gentle. This leads to underexposed, overexposed or ‘flat’ photographs which aren’t very enticing and might seem amateurish.
That is the place HDR is available in – it creates photographs which have a increased dynamic vary than usually potential. It’s a intelligent technical function accessible in most fashionable iPhone camera apps which takes two or extra pictures as a substitute of only one. The primary is robotically underexposed to make sure the element within the brightest components of the scene are captured. The second is overexposed to make sure the element within the darkest a part of the scene are captured. Then it robotically blends the 2 photographs collectively, pixel by pixel. Because it does this it provides precedence to the non-white and non-black pixels in each photographs – which means that element which might in any other case be misplaced is saved. The extra superior HDR implementations help you resolve to what extent the HDR impact is utilized on a sliding scale.
When do you have to use HDR?
The apparent time to make use of HDR is if you end up confronted with a excessive distinction scene. That’s a scene which has each very darkish and really brilliant parts in it. The commonest state of affairs is the place the whole lot above the horizon is gentle and the whole lot under is darkish. Under is a sequence of similar pictures of a fort. The primary was taken with out HDR and uncovered for the constructing within the distance.
The subsequent shot was uncovered for the arch partitions on the left and proper. While these partitions at the moment are properly uncovered the rise in publicity has blown out the constructing within the distance.
For the following shot we’ve used the native digital camera app with HDR switched on.
The outcomes are way more interesting with out trying synthetic. The arch partitions and the distant constructing are all effectively uncovered with a cheap publicity stability between them.
As with most in-camera and post-processing photographic results ‘less is more’. It’s a matter of non-public style however my desire is to solely use as a lot of any impact as is important, and ideally not a lot that it’s noticeable. Within the subsequent three examples the native digital camera app’s automated HDR function has been pretty conservative – which I like.
The primary/left-most photograph was taken with out HDR. It’s not too dangerous, my son is properly uncovered, however the sky is blown out with no element and his darkish garments aren’t revealing a lot material element both.
The second, right-most picture was taken with HDR and whereas it doesn’t look wildly totally different from the primary you may see extra element within the brilliant sky and likewise at the hours of darkness clothes. As well as his face and hand are a little brighter. Let’s take a look at a couple extra comparable situations – each benefiting from delicate HDR enhancement.
The featureless sky within the first shot under is revealed by way of HDR within the second.
Within the instance under, if I expose for the sky my foreground is just too darkish.
If I expose for the foreground the sky will get blown out.
Utilizing a third get together HDR app to I get to maintain the element within the sky and the foreground.
Different examples embrace scenes with robust daylight creating laborious shadows, snow scenes or group photographs the place there’s a combination of sunshine and darkish clothes. Nevertheless, earlier than you resort to utilizing HDR it is very important a) determine the issue you’re making an attempt to unravel and b) see whether or not you may repair it by rearranging your topic(s) or taking pictures from a totally different place.
As I discussed earlier the quantity of HDR you apply is a matter of non-public style. It’s completely acceptable to make use of it to create unrealistic, inventive photographs by making use of extra of the HDR impact. The outcomes will be otherworldly and dream-like.
When shouldn’t you employ HDR?
If you’re making an attempt to realize a high-contrast impact you’ll need to go away HDR alone. It is because HDR tries to take away excessive distinction by brightening the darker areas of a scene and darkening the lighter areas – leading to decrease distinction photographs. So, keep away from HDR in order for you your topic silhouetted in opposition to a brilliant background, or if you’re wanting excessive distinction or black-and-white outcomes.
Within the picture under, if HDR had been used, the sky would have been darker, the particular person leaping would have been lighter with some element revealed, ensuing within the lack of distinction and possibly ruining the drama of the shot.
Pretty much as good as HDR is – chances are you’ll be utilizing it to unravel a drawback that might higher be solved one other method. For instance, in case you’re taking pictures a headshot into the solar or in opposition to a brilliant sky you’re more likely to find yourself with a darkish topic or a burnt out sky. Earlier than you attain for the HDR setting strive switching on the flash. This may fill at the hours of darkness foreground with out burning out the sky.
As a result of the HDR function requires a number of photographs to be taken there will probably be an inherent delay between these photographs. Despite the fact that this delay is tiny in case your topic strikes sufficiently between photographs then you might get unusual outcomes. The quicker your topic is shifting in relation to the digital camera the extra noticeable the issue. Due to this fact, you’ll in all probability need to keep away from HDR for high-speed motion pictures – e.g. quick paced sports activities and so on. The picture under reveals what can occur in case you shoot a fast-paced topic with HDR.
The operating particular person was in a single place when the primary shot was taken by the HDR device, and in one other when the second shot was taken. The 2 photographs had been blended robotically to provide the HDR impact however we see an undesirable blurring or double-exposure impact.
How to make use of HDR within the iOS (iPhone and iPad) native digital camera app
The native digital camera app on iOS units has a wonderful, easy HDR function. To activate it merely faucet the ‘HDR’ choice on the high of the app window – then choose Auto, On or Off. Selecting the ‘Auto’ setting tells the app to resolve for itself when it ought to use HDR. The ‘On’ setting forces the app to make use of HDR each time, and the ‘Off’ setting tells the app to not use HDR.
You may resolve whether or not the digital camera app saves the non HDR model in addition to the HDR photograph. This setting is buried within the iOS machine’s ‘Settings > Photos & Camera’ web page. This may fill your machine’s reminiscence up extra shortly however it does provide the flexibility of utilizing the non-HDR model. That is advisable as a result of you may’t simply take away the HDR impact from a photograph afterwards. If reminiscence/house is a large concern you may all the time take away the model you don’t need to preserve when you’ve checked each variations out. You may determine the HDR model of the photograph by the presence of the phrase ‘HDR’ on the top-left of the HDR picture within the ‘Photos’ app.
One of the best issues concerning the iOS implementation of HDR are its simplicity and its subtlety. You don’t even have any management over the extent of HDR utilized – however that is high quality normally as a result of it does a nice job and allows you to get on with taking extra pictures quite than tweaking settings. The impact utilized is adequately subtle that the typical particular person wouldn’t discover something particular had been completed to the photograph – however once you evaluate the HDR picture to the non-HDR model the advance is often apparent.
Examples of different apps which excel at HDR

Under we’ll take a look at a handful of well-liked ones and provide help to determine the fitting one for you.
Professional HDR X
For iOS units this well-liked HDR digital camera app improves on an earlier ‘Pro HDR’ model we reviewed. It presents a good mixture of ‘out of the box’ simplicity with the choice of superior controls – the principle one being the power to dial in the right amount of HDR after taking the shot.
Probably the most spectacular superior management is the power to place three bins to determine areas of the scene which have to be uncovered appropriately. You’d need to make sure you use the three bins correctly – selecting a darkish space of the scene, a gentle space and maybe one other essential space – probably the topic.
Extra options embrace a ‘rule-of-thirds’ grid overlay, a 2 or 10 second timer, the power to import as much as three exposures out of your digital camera roll which the HDR is utilized to, a zoom function and flash management (together with utilizing the torch), shade, brightness, hue, distinction and publicity controls.
This iOS HDR app has a lengthy listing of nice critiques and appears to be among the many extra skilled instruments available on the market. It presents many nice high quality presets but in addition supplies the high quality management a few of us crave in our apps. It additionally claims to dispose of the ‘halo’ drawback we touched on earlier and minimizes the undesirable side-effects attributable to shifting the digital camera throughout capturing a number of frames.
Obtainable for each iOS and Android units Merely HDR is a little clunky when in comparison with Professional HDR X and Vivid HDR however it’ll attraction to these on the lookout for extra arty, excessive outcomes. The HDR impact will be set robotically or dialed-in.
A beautiful function they’ve included is the power to avoid wasting your chosen HDR taking pictures settings as a preset which might simply be recalled and used later.
