Black and white portraits – blue channel man

Using filtration in male portraiture • channel mixture conversions • shooting in colour for a black and white result

Black and white blue Channel conversion male portrait We automatically think about using channel filtration to create black and white images when we are shooting landscapes, because we are all used to the idea of fitting filters for this type of subject. The reference pictures that stick in the mind that demonstrate what filters do to monochrome images – the deep black skies and fluffy clouds of the red filter – are generally landscapes in which we can see how blues darken and green grass lightens. In fact, you probably wouldn’t shoot a black and white landscape without thinking about filtration.

We don’t associate lens filters with portraiture in the same way, unless warming or adjusting a colour picture, but sometimes red filters are used to reduce the effects of skin blemishes. With this in mind when converting a colour portrait image to black and white I often use a red channel bias in Channel Mixer (Image>adjustments>channel mixer) to lighten the redness of spots, skin patches and veins close to the skin surface. This looks great for women, as it can leave a flattering facial glow as well. But it really doesn’t look macho enough for portraits of men.


A portrait converted to black and white via the red, green and blue channelsI have found the channel that delivers the more manly effect is the blue channel. It adds depth to the skin and presents a more tanned, or weathered, look (I know, but you can still see it in black and white!). The blue channel makes men look stronger and more heroic, which I think is what most men prefer. And the deeper and more complex shades of this kind of conversion provide the ideal base for adding a colour tone too. There is so much more grey in black and white images converted using the blue channel that toning and staining colours have much more impact.

By Damien Demolder If you find a blue channel conversion produces too strong a result remember that you don’t have to use it on its own. My favourite channel of all is the green channel, as it has lower contrast and better sharpness than red or blue, and I like to mix it in with the others to rein in any over-blown effects. Try mixing 50% green and 50% blue for a more restrained image.

Obviously to make use of these effects and options you need to be shooting your portraits in colour. I find that shooting everything in colour gives me the most flexibility, so I shoot in colour even when I know I will only want a black and white final result.

Simple pictures – Blue Bay

Creative white balance – simple composition – previsualisation – looking

Blue Bay, by Damien DemolderThe sun had well and truly gone at this stage, and its setting had not brought the spectacle I had been hoping for. Nice enough, the colours hadn’t played across the sky as there were simply too many clouds. I was determined though to go home with something in the bag, so I sat down to take a rest and to have a think. I had brought a folding chair with me to do this, as I was beginning a faze of purposeful looking and contemplation. I figured that rather than rushing between locations and snapping what occurred to me first, I should try to slow down a little and spend more time looking. The chair thing would help me do this, as by sitting I would be more likely to stay in one place for longer. This wasn’t a trekking sort of day, as I knew I wasn’t going anywhere other than on this stretch of beach. I could carry the chair, dump it down and work around that as a base.

I had been to this location so many times before, and although I had taken plenty of nice, and even good, pictures there, I never felt that I had quite captured whatever it was that appealed to me about it. In actual fact, the issue was that I hadn’t actually identified what it was that appealed to me – which kinda makes it difficult then to capture it in a photograph. The idea of the chair was that I would sit for a while looking at the scene to try to unravel the mystery. If I sat I wouldn’t be bothered by the weight of my camera bag, or the urge to move on you get sometimes when you stand, so I could sit in comfort until the answer came to me.

I’m not sure that I really did find the answer to the question I had in my head, but I did find an answer to a question I hadn’t thought of. As the sun went even further below the horizon and the land areas became silhouettes against the sky and its reflection in the sea I realised part of the attraction of the place is the curved line of the shore around the bay. In the simplified form of the monochromatic moment I saw the light. Where I live we don’t see much sky, as there are houses and trees all around, but here the sky is massive, stretching right down to the ground – so the big sky is one factor. And the shape of the coast line is the other.

Waiting until the sun had gone the sun turned a cool blue that showed up perfectly in the daylight white balance of my camera. My eyes were seeing grey, as my brain filtered out the evening shades, but the camera was able to help me see the reality.

I tried plenty of compositions, but what worked best was when I just concentrated on the principle elements of the curve and the sky. With the camera angled upwards slightly I got rid of the foreground shingle and plants that were fighting for attention in the dim lighting. Removing those details simplifies the scene and makes it clear what I am trying to draw the viewer’s eye to. And exposing for the sky has brought out its detail, and kept the land mass to a basic silhouette.

I don’t think I have really captured the essence of this place yet, as this shot is a bit of a side track. I’m actually quite pleased as it means I can still go back and carry on trying – it’s a wonderful place.

Making a frame – matting and adding text

Sunday, October 5th, 2008
Improve your on-line presentation – add titles to your images

Creating a virtual photoframePictures should be able to stand on their own two feet without embellishment, but there are few that don’t look at least 30% better when they are mounted and framed. Obviously, this sort of treatment is reserved for prints, but even those who show their work on-line or in an electronic form can benefit from this form of presentation. We don’t frame every picture we take, only the best, so when we add a frame to an image, even electronically, it sends the message that we think the picture in question is special. Framed images have that prestigious air about them.

When ‘framing’ this picture I decided to go for a multi-layered effect to add depth to the mount. This just echoes the effect you get when you use a double window mount, with two shades of card and the white edge that shows in the cut. When working this way it’s best to create the outer-most mount first. There are a number of ways of to create these mounts, but I’ll show you a simple one.

Make a bigger canvas

First you need to make the background mount, which you do by enlarging the canvas the image sits on. Go to the top bar of Photoshop and selectCreate new canvas Edit>Canvas Size. Ensuring the central square is selected as the Anchor, type in the size you want the final picture to be leaving a bit to spare so that you can crop later on to the final dimensions. If your picture file is 7x5in @ 300ppi, for example, create a background canvas that measures about 10x10in @ 300 pixels per inch.

With the image sitting on a bigger plain background use the magic wand tool to select the out line of the image so you can add the faint shadow effect.

Add a stroke – or two

Select image for strokeTo create this first grey layer, that will look almost like a shadow in the final image, we’ll use the ‘stroke’ feature of Photoshop. With the whole image selected head to Edit>Stroke. The box offers several options, one of which is width/colour. The width of the stroke you will need at any point depends on the size of the picture you are working on. Obviously a 20 pixel stroke is proportionally bigger on a 600×800 pixel image than it is on a 2000×4000 pixel image, so you may have to try a few different settings before you find the right width for the picture in question. Picking a colour is comes down to your own personal choice, but I find shades of grey most effective and the least offensive to the majority of people. Also in this position, between the picture and the white ‘card’ the effect is supposed to be shadow rather than anything that has a colour.

Stroke colour pickerThe box below the width/colour options asks you to determine where the stroke goes. ‘Center’ places the stroke on the selection line, so half of the stroke’s width covers part of the image, and half falls outside of the image, while ‘Inside’ places the stroke entirely on the picture area, and ‘outside’ places the strokes thickness on the ‘card’. If you want to avoid losing any picture area select the ‘outside’ option.

Once that’s done deselect the image and reselect it to include the new much wider stroke, and then add the extra stroke to create the white area shown in my example. I didn’t actually use white, but a very light yellow/grey instead.

Colour the ‘card’

Then you need to add a colour or tone to the rest of the ‘card’. To do this use the rectangular selection tool to draw a box around your picture leaving the amount of white showing that you want. Go to the top bar and click on Selection>Invert to select everything other than your picture and the amount of white you want showing. You now need to add the colour or tone to the card. You can pick any colour you want to compliment your image, but I tend to stick with neutral shades to grey. Dull perhaps, and to everyone’s taste, but grey has the benefit of working with every picture. Select your colour using the colour picker, and then use the paint bucket tool to flood the colour onto the card

Add text to record the details

I like to write on these frames, especially for portraits, so the picture can have a name or so we can all remember when the picture was taken and who is in it. I’ve been doing a series of birthday pictures of my family, so I use this space to record the date, name and age of the subject so the piece becomes more of a historical record.

I create a text box and write whatever I want to in white. I then align the text with the picture, usually in that bottom right hand corner,Fade text layer and then fade the text layer so reduce the text to a grey rather than a bright white. White tends to stand out too much and can take away from the picture. Obviously you want people to be able to read the text, but it shouldn’t be the first thing they see.

Although really designed for web use, these frames, if done neatly, work well in print too. I saves actually cutting window mounts (or matts) and is a quick and effective way of presenting your images in an album or portfolio.

If you don’t have Photoshop you can create these effects in a wide range of other programs. I have used the simple application Paint to do the same thing just by creating backgrounds that the image is pasted onto, as well as Gimp – which offers for free much of what you pay for in Photoshop.

The original image, in colour and unframed

Creating a virtual photoframeHut on the Blackwater navigation
Another example of how this technique can be used. In this case
I printed the image with the frame and text together. The text adds a formality to the shot, making it more of a record or postcard.

Create new canvas
Create a new canvas size that’s bigger than the image. Here the image
is just under 7in square, so I made the canvas 10in to allow a 3in border.

Select image for stroke

Select the image area with the magic wand tool ready
to apply a ‘stroke’

Stroke colour picker

The stroke size you need depends on the image size, so experiment
to find what is right for your picture. Choose the ‘outside’ option and
then pick the colour you want to use. I tend to stick with neutrals

Select the outside of the first stroke to create the second. Make this a
big one, as you can crop it away when you create the
background ‘card’ colour later.

Fade text layer

Write your text, and then fade the layer to create a
more subtle effect
