Learn HDR in Photoshop, Colin’s HDR

 photography tutorial

I originally wrote this tutorial for Photoshop CS3, in the years since then, Photoshop has gotten a couple

of big upgrades in the HDR area, and we are now at Photoshop CC. I have also learned a great deal

ore about the sub!ect, so I decided it was tie for an update. "his tutorial will wor# for all versions,

including CS$ and HDR in Photoshop CC. In CC Caera Raw was added as an option, ore about that

soon.

%hat is HDR and why do we need it&

I n this tutorial we will ta#e a loo# at HDR photography. HDRI 'High Dynaic Range Iaging( wasoriginally used in 3D and is now in full force in photography. )asically it*s the process of ta#ing ultiple

e+posures and erging the together into a single 3 bit iage. -et e e+plain

 0 caera is capable of capturing a liited aount of tones in a single photo 'we call this dynaic Range,

the range of tones that can hold detail between pure blac# and pure white(. "ypically we sacrifice

eleents in a photo when we set the caeras e+posure. %e eter for the ost iportant part of the

scene. 1or e+aple let*s loo# at the series of iages I shot at the )radburry building in -os 0ngeles. "he

center iage is a typical e+posure, showing an average etering to produce the ost detail possible.

2otice that the detail outside the door is lost because it*s too bright. 0lso the detail on the stair rail is lostbecause it*s too dar#. %hen you are at the location, you are able to see all these detail with your eye, this

is because the huan eye can see a larger range of tones than the caera can capture on the sensor or 

fil in a single photograph.

 

"he solution is to ta#e ore than one photograph and brac#et the photos. Shoot a noral e+posure

'center iage(, then undere+pose 'left( to capture the highlights outside the windows and overe+pose

'right( to capture shadow detail. 1inally, erge these photos together to produce a single iage with a

larger range of tones that can now show all the details in the shadows and highlights.

This tutorial will show you how to complete this process with the minimum fuss.

"ips for photographing HDR

1irst we need to capture our source iages with our caera. "echnically you will need to shoot a

iniu of photos with different e+posure settings to create a HDR. I personally get good results fro

3 shots. I li#e to over e+pose and under e+pose by stops each. I #now this is a bigger brac#et than

soe people are cofortable with, but for the type of HDR iages I li#e to create 'cityscapes(, this wor#s

great. If you*re shooting people, you ay want to reduce this to single stops.

Soeties you need to capture ore than 3 e+posures. It really depends on how uch contrast is in

your scene. 1or the e+aple of the )radburry building, I captured a series of Photographs inside a dar#

building in -os 0ngeles with a sunny day outside a glass window. I needed 4 photots with stops apart in

order to capture the entire dynaic range of that scene. 5ou ight be able to capture a lower contrast

enviroent such as a foggy day in a single frae. )ut once again, for the a!ority of HDR photography 3

shots are usually perfect. I set the caera for 0uto 6+posure )rac#et and stops 7 and . 8a#e sure that

you only change the shutter speed. If you change the aperture, the depth of field will also change,

Page 3: Learn HDR in Photoshop

producing unwanted blurring in your final coposite. 9se a tripod if you can, otherwise support yourself 

on a wall or solid ob!ect to reduce oveent between fraes.

2ote 1or real HDR, you shouldn*t use a single raw iage and e+posure it several ties as soe people

suggest. "his is unnecessary, as you can use the Shadow and Highlight recovery and ad!ustent brush

in Caera Raw or -ightroo to bring out the sae aount of detail in the photo. 0lso there has beenisinforation circulating, using the ter :Single Iage HDR;. "his is #nown as pseudoHDR. 5ou can*t

get HDR/ (HIGH / Dynaic Range( fro a single SDR 'STANDARD / dynaic Range( photo. It*s li#e

:single spea#er stereo;, the digital inforaition !ust isn*t there. 5ou can apply a toneapped effect to a

single iage for a grungy feel. It*s psudo HDR, but not to be confused with true HDR.

1or ore details see the full <.= hour video / HDR and Photoshop

HDR in Photoshop tutorial

Step 1

Start with 3 iages. >ne noral e+posure, the second undere+posed and the third overe+posed. In this

case I used stop brac#eting. 0s I shoot a lot of city scapes I can get away with stops, because I*

ainly shooting flat surfaces and banding and posteri?ation isn*t such a proble. If your shooting rounded

and curved surfaces you will want to lower your brac#eting to get soother gradients, although there is a

lot of overlap already in the tones as a decent DS-R caera can capture around @@ Stops of e+posure.

I set the brac#eting on y caera to stops. "hen I set the shooting ode to burst. %hen I hold the

shutter down, 3 photos will be captured. I shoot in the R0% forat for the widest possible dynaic range.

5ou can still create HDR if your caera doesn*t support R0%, but bear in ind a !pg is only an Abit file.

8a#e sure you shoot in 0perture Priority or in 8anual. 5ou want to brac#et the e+posure tie, not the

 0perture. If you change the aperture, the depth of field won*t be consistent and you*ll get blurring. 0lso

avoid any oving sub!ects in the photo or you*ll get :ghosting; where soething is only in one frae and

will appear very strange in the final. If you loo# at the three iage that I used here, the iddle iage has

a lot of detail. However, the details in the shadows are lost in the boats and the city lights are too bright

and lose detail inforation. "he left iage is under e+posed to pic# up the details in the highlights such as

the buildings in the bac#ground. "he right hand photo is over e+posed by stops to pic# up the detail in

the shadows, such as the hulls of the boats and water reflections.

Step 2

"ie to erge the photos together into a single 3 bit iage.

Choose 1ileB0utoate B8erge to HDR Pro. "his wor#s on Photoshop CS CS$ 'CS Doesn*t have

auto align and it*s called :8erge to HDR on versions older than CS=(. Choose either iages or folder. I

organi?e each set of photos in its own folder so I used the folder option. Select your photos to erge.

"urn on 0uto 0lign in Photoshop CS37. Clic# >. 'Photoshop uses 0utoalign technology that even

allows you to create HDR without the use of a tripodE(

Step

5our iages will now be erged into a single photo. 5ou can turn off individual photos by un chec#ing

their bo+es on the left filstrip. If you get soe blurring caused by caera sha#e in the longest e+posure,

you ay want to turn off that photo. If there is ghosting because of oveent, clic# the bo+ Reove

Fhosts.

'%hen the ode is at @$ or A bit you will see settings li#e this, if 3 bit is selected, it will loo# li#e step <(

Step !

"he erged result is a floatingpoint 3 bit iage. Change the ode to 3 bit. 5ou can view the available

tones by sliding the %hite Point slider. 2ote, this slider doesn*t change the iage, it is there for you to

e+aine the range of tones, because a onitor is incapable of displaying all the tonal detail in a 3bit file

all at once.

2ote In Photoshop CC there is a new option. :Coplete "oning in 0dobe Caera Raw;/ "his option

isn*t in CS$. If you are on Photoshop CS$ and lower, !up to step = right now.

If you are on CC and the :Coplete "oning..; button is turned on, you won*t be able to ove the slider.

Clic# the option off and you will be able to ove the slider and continue with the rest of the tutorial !ust l i#e

in CS$.

However, when the option is turned on, you will be able to use Caera Raw for the "one 8apping instead

of the HDR Pro settings. In this case, s"ip to step #$.

However, I recoend learning both ethods as they each have erit. "he HDR Pro tone apping 'step

=7( will give you ore control and enable you to create a surreal effect as well as powerful HDR controls. 0CR 'Caera Raw( has the advantage of being able to do very realistic HDR toneapping without too

uch effort.

Step %

5ou could do your toneapping right now if you li#e, but I li#e to save a 3bit negative. Clic# > to erge

the photos into a 3 bit iage. 2ow is a good tie to save your file. Save as a psd, tif or open 6GR.

If you are wor#ing with 3D and are wanting HDRI for I)- lighting, enviroents etc, save as open 6GR as

Step &

In order to use the photos, you*ll need to convert the to @$ or A bit iages. %hen we convert the we

will create what I call interpretations of the photo. "he reason I say this is because we have unliited

ways we can a#e the photo loo#. %hile we have this huge dynaic range available in 3 bit, we will no

longer have those options after conversion. 0lways wor# fro the saved 3 bit version, and then convert

ay want to go bac# to it any ties.

Choose IageB8odeB@$ bit 'or A bit(. 2ow we get to play with soe fun options. 5ou*re now at the tone

wor#ing with a larger dynaic range than you*re used to. )ring out the detail in the iage, but don*t forget

to put soe shadow in there or it will loo# washed out and fa#e.
