Doorway – blending technique in Photoshop CS3

Doorway shot with Nikon D40 and 18-55mm kit lens

The technique for making this is as follows:

    Photograph shot in colour
    Foreground colour in colour picker set to the same colour as the stonework
    Go to Filter>sketch>graphic pen, and use the sliders to produce the sketch image you like
    Go to Edit>fade graphic pen>blend mode set to multiply>opacity slider reduced from 100% to suit

Lightroom 1.1 released

Just four months after the release of Lightroom 1.0, Adobe have released an update that is free to registered Lightroom owners.

Changes in the DEVELOP module
Overall, the tools in 1.1 bring the Develop Module closer to the tools that were introduced recently in Camera Raw 4.1, which is the RAW converter in Adobe Photoshop CS3. So the two programs are drawing closer together in terms of the tools to develop images.

For example, there are now the same extra sliders in the sharpening tool in the Develop module as were introduced in the improved sharpening tool in Camera RAW 4.1 in Photoshop CS3. As I have already commented in an earlier post, that tool is extemely good, and with it, it is easy to supress halo effects and choose the areas that one wants to sharpen.

And as with Camera Raw 4.1, the effect of each slider can be viewed independently in black and white, by using the ALT key (and whatever the equivalent is for PC users).

There is a standard default setting for RAW files that introduces some sharpening, which can of course be left as it is or altered with the sliders. It is worth noting though that the default sharpening for any format that has already been developed (jpgs, PSDs, TIFs. etc.) is zero because of course these have already been developed.

There is also an additional Clarity slider added above the Vibrance and Saturation tools. It increases the contrast as the micro level making the image look more punchy but it does need to be used delicately or it will make the image look over contrasty.

The Luminance noise reduction tool is said to have been improved ‘behind the scenes’ as it were with new algorithms. Having upgraded from 1.0 I can’t tell whether it is improved as I have no comparison other than my memory.

And there is also a defringe tool in the Lens Correction tool – again as with Camera Raw 4.1.

Changes in the LIBRARY module
There is now ability to export original RAW files, which is in effect a ‘copy’ facility for original files.

For managing files there is a change in terminology from 1.0, as Libraries and Library Databases are now called Catalogues. This does not affect the Library module, which continues to be called that.

It is worth taking a step back and looking at what catalogues are. They are databases that keep track of where files are and the information in them.

With Lightroom, one can see previews and data even if the original image is not accessible – as for example it is stored on a CD or on an external hard drive that does not happen to be connected to the computer.

By way of contrast, in Adobe Bridge the images must be accessible so that Bridge can browse them.

in Lightroom, if the image is accessible but the user has moved it somewhere else (for example somewhere else on the hard drive), Lightroom will try to find a new path to it, and if it finds it then one can make any alterations one wants in the Devleop module. Otherwise, one can look but not change the image because Lightroom cannot locate it.

Photography with a flatbed scanner

Faltbed scanners, even cheap ones, have ample capacity to make useable scans of large objects. When I say large, I mean anything that is significantly bigger than small detail in a frame of 35mm film.

Some say we may have reached the limit of quality for consumer-grade flatbed scanners, with the appearance of such models as the Epson V700 or V750 or the Canon 9950F. For detailed reviews of what they are capable of, take a look at photo-i which is a very good site.

While those scanners might be able to resolve the details in frame of 35mm film adequately, you would think that an old Epson 1660 flatbed scanner would not be up to the job. And of course that is correct up to a point. But here is a scan from an Epson 1660 that I bought a couple of years ago secondhand for a few dollars. I downloaded the driver from the Epson site and cleaned the glass with window cleaner, and scanned this old photograph.


The next shot is small crop of a significantly larger object – a clump of dried grass, scanned at 500dpi and 48bit colour.


So next time you want a change, and want to put away the camera, try a flatbed scanner for anything that doesn’t move and is flat enough to be considered more or less two dimensional.

Lightroom and Photoshop CS3 – some comparisons

I have already posted reasons why I think CS3 is a substantial advance over CS2, but in a nutshell, Adobe Bridge is much quicker and more stable than Bridge in CS2, and the sharpening tools in Camera Raw 4.1 are much better than in previous versions and perhaps better (certainly different) than in Photoshop ‘proper’.

For those not familiar with how Photoshop is bundled; it comprises a Photoshop ‘proper’ module, Camera Raw, and Bridge.

If one is processing RAW images then Photoshop ‘process’ comprises at least two elements – Camera Raw, and Photoshop ‘proper’ – because the image has first to be converted to a Photoshop document (PSD) before it can be further processed in Photoshop ‘proper’.

And if one wants to browse a number of images then the bundle also includes Bridge, which allows one to view large preview jpegs of images of many types, including RAW images.

So what does Lightroom offer?

Well today I found one reason to prefer Lightroom when I wanted to produce a collection of jpegs for the web. Some of the images were jpegs, some were PSDs and some with RAW files.

Lightroon swallowed them all and spat out webpegs in short order. It will also produce high quality jpegs from a variety of source files if you ask it to.

Compare Photoshop where, if the original file is a RAW file, you have to open it and save as whatever format you want – but on a file-by-file basis. There is no batch-process that will cope with RAW files.

Lightroom also offers an additional way of using the tools for adjusting tone and hue/saturation/luminance(HSL). There are sliders as in photoshop, but there is also a Target Adjustment Tool which, once activated, operates by dragging the curser up-down-left-right around the selected area.

If, for example, ‘hue’ is chosen, then as the tool is dragged, the hue changes. It is easier to do (and see the results) than to describe. What the tool does not offer is the ability to isolate the changes to only part of the image. If one chooses to change the hue, then all parts of the image that are a similar hue, are changed.

It is a nice tool but it would be so much better if the chosen area could be set to ‘contiguous’, or selected in some way akin to the marquee tool in photoshop.

Blended layers in photoshop

I am sometimes a fan of making photographs that look as real as I can imagine the scene or the person actually looked. That usually translates into a sharp photograph, or at least that some part of the image is sharp. On the other hand, I sometimes care only about the look of the final image and do not care at all whether it mirrors the scene, or indeed looks like a photograph at all.

These two photographs were made by taking an image and in each case, pasting it over a scan of a sheet of art paper that I had soaked in coffee (and dried beofore scanning it!) then blended in photoshop – with the blending mode set to ‘multiply’.
