Star Burst – Photo Zooming

I thought that at this celebrative time of year I would find an appropriate festive image that might capture some of the excitement with the starting of a new year.

The image below was photographed using a twist and zoom technique on your telephoto lens. You zoom in or out on the lens, while you are pressing the shutter.

Depending on the length of the shutter speed and how fast you rotate the lens, you will get different patterns. A tripod ensures that all radial lines are straight, but especially if handheld, as the images below will attest to, strange patterns can emerge.

If you are wondering what the original image looked like. Below are 2 hints from cropped areas.

When capturing zooming images such as these, there are a few simple premises that help you to influence the final outcome.

All bright objects will produce the streaking light effect. Therefore darker backgrounds and having the lights being the source of interest, produce more dramatic images.

When holding handheld, do first try and find something to lean on, and then begin the telephoto-zoom rotation before pressing the shutter to reduce camera shake.

The slower the shutter speed the greater the effect, but then more difficult to handhold.

The images where taken inside the main lobby of the Tokyo National Theatre of Japan where we had gone to see a wonderful Kabuki play.

This is from the top floor walkway.

Not Quite Steamed Christmas Pudding

First of all and most importantly, I want to wish you a Merry Christmas or whichever holiday celebration that is significant to you at this time of season and a truly great upcoming New Year. Also a thank you to the readers who drop in to read some of these articles, as this is what keeps me excited about writing more.

Not all my photographic shooting is well thought out and planned, sometimes I am just a tourist with a camera, as an example with the following image.

This image was captured outside on one of those crowded and uniquely interesting side-streets in Chinatown in Yokohama on the outskirts of Tokyo. This is such a visually rich and vibrant area with brilliant colours, great people and interesting food, which I hope you all get a chance to visit.

This photo was taken without use of flash, as I wanted the local street lighting to naturally highlight the image. I had to crank the ISO up to 800 to still be able to get a decent shutter speed of 1/30 at f4.5.

This is one of the times I am so thankful that I shoot in RAW format. The image on the left is the default RAW setting, which would be the result if I shot in jpeg mode. Terrible tungsten (red) colour cast and the red channel of the dumplings is almost completely clipped. The image on the right is corrected for White Balance but as you can see it is still a bit dark in many areas and yet the dumpling in some sections are a bit blown out.

When working on a photograph, it is easy for your own biases, from memory of when you where there, to influence how well the image appears. There are several techniques I use to examine an image for strong compositional elements to help me focus better on these areas. Below I used 2, one to apply a steep curve to drastically increase contrast and the other, ‘find edges’ on this darken version to really see what stands out.

It becomes apparent that the dominant elements are the diagonal lines created with the hand, the tilted steamer and also by the tongs. There is also the re-enforcement of circles throughout image from the steamers and dumplings.

The image below identifies the changes I decided to undertake to keep focus on those primary elements.

You can see from the image of the layers palate that there was a lot of effort that was needed to make all the changes.

This image was made a few years ago before a very useful feature, found in Photoshop CS3, was made available. This is the smart object layer. The old method was to create a separate file and reduce the exposure to get all parts of the dumplings from being blown and then copy and paste it into the working file. If there was something off with this copy, then you were required to try again. With smart layers, I just open this smart layer and then I am presented again with the camera RAW setting, which I can re-tweak over and over again, and mask out the parts I don’t want.

For some of you, this may seem like too much work however, for those images that you plan to print for yourself or plan to sell, it is important that all the details in the image are corrected.

This is an image of a great buffet where the food goes around on a 150 ft conveyor belt and you just take those items which you desire.

More food available on the street.

And now, a restful place to sit after all that eating!

Oooops! Inverted and Upside Down

I few weeks ago there was B&W print competition at my local Camera Club, with a topic of ‘My Backyard’. I only had one photo that I thought might win and I was trying to find creative idea for another entry that would be of sufficient caliber. I have learned over the years entering competitions that, while judges do rate on the technical and compositional elements, they also seem give a special emphasis for not-your-everyday-image found in your locale. Visual repetition even with great images tends to not quite cut it.

I therefore decided to experiment with a colour image of ornamental grasses that I was fond off. A negative B&W version was created and was also turned upside down to give the appearances that the light was falling correctly on the subject. While this was not my favorite of the 2, it did win an ‘Award of Excellence’

I find that for fine details or subtle tones, the web version, can never quite create the same visual impact of a well-printed image.

For the strip-line version, please click on the thumbnail image below to see the larger (1500x 450) version were the details will be more visible.

I had such fun creating the examples that I may have gone overboard in showing too many in the blog, but I do hope you enjoy them and importantly can see the potential for creative ideas by experimenting. In all cases I like the inverted version the best, but you will have to decide for yourself whether it works for you.

One large benefit with creating a inverted tonal version whether in B&W or colour is that it helps you to see the compositional elements in the image separately form the normal and how they are balanced throughout. This is because with a regular image it is too easy to focus on the image itself because you understand it within it own context. When it is inverted it is harder to figure it out and the compositional elements now becomes dominant parts.

In the above image, I also used a steep tonal curve just on the curled banana leaf tip and added some darkening to give more of a 3D effect as the inverted version below I though was a little flat.

I thought the tulip version created a more dramatic, mysterious and magical version.

Sometimes completely different image will emerge as shown below. This image for me appears almost like a star going nova with its explosion.

As I stated earlier I almost couldn’t stop doing these and have included a few more of these progression series below and one with just the final versions.

It can even work for colour-inverted image but becomes a bit harder due to the wonky colours you will get. In the final colour I used an inverted B&W set to darken mode to punch up the colour more and tweaked the Hue/Sat to my liking.

Do take the time to experiment with your photography, whether with your approach to the subject or through photo-editing techniques. It will help you in the future to visual new subjects that may not have caught your eye under normally .

Lily and the Dancing Stamens

With the snow season finally settling in, it becomes harder to capture interesting shots every week. It is more physically demanding and you start to see a repetition in snow themes. Therefore this week I thought I would focus on a singular image and describe the photo-editing approach I took to enhance it to match the vision I had.

When it comes to your personal photography I find that there are no right or wrong approaches. There is your vision and what excites you. Now if you are a commercial photographer or if you want to make a living selling your images, that’s different. It’s the client that decides what works, unless of course you are such recognized brand that your work establishes the standard.

While I use Photoshop for my photo editing, I will try and keep the processes generic so that the same techniques can be used with any photo editing software.

The title for the image is the Lily and the dancing Stamens and as you can probably guess, the main focus will be the stamens with a secondary focus being the petals of the lily.

Whenever I work on an image that I will take to the print stage, I always like to mark-up the photo with the editing that I plan to undertake. I will at times use layers to keep notes as I am working through the image, which becomes a good reference tool later when re-visiting an image and figuring out why you took that approach.

The image below shows the planned changes on the original RAW version from the camera. The thinner lines are used to show less effect needed.

The anther parts (wow! some biology too) of the stamens are normally very monochromatic and uniform in tone and I needed to enhance these to make them jump out more from the very vibrant colours in the background. Pollen by nature is very soft, unless you are looking through an electron microscope. I applied a little sharpening to bring out some detail in the anthers but no other parts, as I wanted the soft focus of the background to remain.

Using a mask to just apply changes to the anthers I also increased contrast by using an ‘S’ curve. Then, on a new layer, copied only the anthers, converted it to B&W and inverted to create a negative and set the layer to colour dodge. This will make any subtle yellow tones on the sun-lit side of anthers a very strong yellow. The opacity was reduced until it appeared that the left edge was receiving a low horizon sun effect. A very steep ‘S’ curve adjustment layer to fine tune effect was added.

This image shows part of the colour dodge Layer from the B&W inverted anthers.

The second part of the stamen, the long green filament, needed to also stand out more. By using a colour saturation layer and only targeting the yellow channel I was able to make these filaments glow a bit.

This zoomed image shows in better detail the changes performed.

The diagonal petal behind the stamens was not very vibrant, which is fine, as I did not want it to detract from the stamens. The far right petal, I thought, was too light especially since it was near the edge of the image. I needed to increase the colour saturation and at the same time darken the overall colour. I used a black layer set to Overlay, which causes the colours to be very intense. A Hue/Sat layer was added to reduce a bit the strong red intensity.

I found the edge where the 2 petals joined needed to be a little darker on the right petal and I darkened this just a bit.

This is an image of all the adjustment layers. I take the time to record information in layers should I, at later date, decide to fine-tune another way.

Here are a few more images of the lilies from the days shoot.

If you have any questions about the processes I described, please feel free to ask me.
I can even send you a scaled down version of the Photoshop ‘.psd’ file so you can better see the effect, if you send me your email address.

Thanks for reading.

It fascinates me that there is a variety of feeling about what I do. I’m not a premeditative photographer. I see a picture and I make it. If I had a chance, I’d be out shooting all the time. You don’t have to go looking for pictures. The material is generous. You go out and the pictures are staring at you. -Lee Friedlander, "Documentary Photography - LIFE Library of Photography" , page: 178

My Winter Snow capped Friends

As some of you may have been aware, at least from my previous blogs, is that Fall and those parts we associate with the pleasant memories is slowly ebbing away. There are those other periods when it becomes a precursor for the hardest season of all - Winter.

I truly enjoy being outside, even when the weather may not be at its best, because there are so many changing elements and other obscure things to observe around you.

During the night the temperature was just right that, when it snowed a couple of inches with large and delicate snow flakes they just hung perfectly from all the tree branches, shrubs or anything else that was outside. It was then I noticed some interesting patterns that played with the diffused light. There were a few remaining garden plants, although dead, were still standing into late fall season and providing some interesting textures in the backyard.

These plants with the large dried flower heads and snow-covered caps gave me the impression of a group of dwarfs sitting together. I was never quite able to capture that impression.

I thought that I might be able to somehow capture this on film and went inside to get my camera. In hind sight, even though being so close I should have also grabbed my snow clothing as I was not quite able to get down as low (lay flat on the ground) as I wanted to. I find once you are out shooting, it becomes harder to go back and adjust other thing.

In the image above, I embedded 2 RAW files as ‘Smart Object’ layers in Photoshop. This allows me at anytime to go back to the RAW settings and fine-tune them just for that layer. One layer was set to a cool temperature to best bring out the blue in the snow. The other smart object layer was adjusted to the correct white balance setting to permit me to give the plants a more vibrancy in their colours. I decreased the orange saturation to make the main stalks appear more woody and then increased saturation and luminance in the yellow channel to make the leaves pop more. Masks to just let through each of their own main features.

When there is a lot on snow or other broad monotones, it make it easy to quickly bring out the creative elements by being able to colour control only a few elements in the image.

This is the version I selected mainly for the contrasting greens and reds. The image below shows the other colour variations I made on the same image.

Photographing snowy objects under overcast conditions is a difficult task to be able to bring out the rich tones, at least in some parts that most of us are familiar with. The camera will, in auto mode, try and set the exposure for the snow to mid grey when snow fills most of the frame as opposed to pure whiteness.

All cameras try to set the exposure so that the majority of pixels fall around the mid grey point. This is because most of the time the useful information falls around the mid grey tonal range, except for black cats and snowy landscapes or bright white sandy beaches. The camera doesn’t know, unless you have program setting for snow and black cats, what the image is about. It just likes mid grey.

To solve this, increase the exposure about 1 1/2 to 1 3/4 stops. The histogram is a very useful tool that can help overcome this auto over compensation by showing you where the lightest points fall and thereby helping you to fine-tune the compensation changes. Always try to expose to the right by keeping the lightest pixels with any information just starting at the left edge on the right side of the histogram display.

Whenever you have a chance, change the colour in some parts or all of your images. It helps to increase the creative mind by just playing around. Who knows what will turn up.

I have been frequently accused of deliberately twisting subject matter to my point of view. Above all, I know that life for a photographer cannot be a matter of indifference. Opinion often consists of a kind of criticism. But criticism can come out of love. It is important to see what is invisible to others. Perhaps the look of hope or the look of sadness. Also, it is always the instantaneous reaction to oneself that produces a photograph. -Robert Frank, Page 115 of U.S. Camera 1958. Published by the U.S. Camera Publishing Corp. in 1957.
