Leicester countryside - Image processed with Topaz DetailReview of Topaz Detail

The Topaz Labs range of plugins

Keith Cooper has been looking at 'Detail V3.1' one of the range of image processing plugins from Topaz Labs.

Whilst we use Photoshop for image editing at Northlight, the Topaz plugins work with a wide variety of image editing packages, including Paintshop pro and iPhoto.

The range of functionality is so broad that the reviews are split up over several articles.

Update - Note that Detail 3.2 has mainly cosmetic improvements, and follows Topaz's recent improvements to the look and feel of their interface design. There is an example at the end of the article.

What do you get with Topaz Detail?

The plugin installs as an 'add-on' for other software and provides a range of preset adjustment options and ways of fine tuning settings.

Topaz Detail addresses a large range of contrast related adjustments, both in respect to colour and aspects of contrast at different scales in your image.

Many aspects of how we perceive a photo are based on levels of contrast, both of image brightness, and of colour.

There are all kinds of subtle effects around how our brains process the data from our eyes, that are not immediately obvious, and sometimes counter-intuitive.

Look at the graduated grey bar in the middle of this image...

Is it really graduated though? Move your mouse over the image to replace the surround with a solid colour.

Local contrast illusion

You might now know it's a single tone, but your brain wants to force a different interpretation. Altering tonality in the graduated surround changes our perception of the (unaltered) bar in the middle. Think of this applied to parts of images, at different scales, you can change how parts look with quite subtle adjustments.

In the early days of image processing, contrast adjustment was globally applied and that was that. It's still a useful global image setting to adjust, but there is a lot more you can do.

What about just altering areas of the image with low contrast, or just the highlights, or just the green parts?

Advances in computational power now let you apply complex image analysis before setting different adjustments to different parts of your image. Only a few years ago, this processing might take many minutes for each adjustment, now you can get near real time feedback as you alter settings.

I'll go through the basics of how the Detail plugin can alter your images, but remember it's up to you to decide if the adjustments match what you want for an image.

The plugin

The plugin is applied via Photoshop's filter menu (see the summary at the end for all the other applications you can use it with).

In this first view, I've opened it for an image of a huge horse chestnut tree, near a local church.

The plugin analyses the image (this can take a moment or two with larger images) and will initially duplicat your last used settings.

The basic options are:

The side-bars can be collapsed if desired.

Main plugin window

A split panel view is useful for seeing changes.

This view shows a fine detail removal setting. Note how detail removal is not the same as just blurring an image.

split before and after view

Colour adjustments are also included in some settings.

application of preset adjustment

Note how the strong adjustment of yellows might be OK for the leaves, but fails on the brick buildings.

Another preset 'Cool dreams' - no I don't know where some of the names come from... ;-)

sample image adjustment

There are pop-up tips to give further information about some settings.

Do make the effort to read the usage guide and tutorials, since there are so many adjustments, it would be easy to miss things.

Another setting, showing strong detail enhancement.

microcontrast adjustment

If you're experimenting, then there is a random settings 'I feel lucky' button.

If you find something you like, then you can always save it as a custom preset. You can then come back to it and fine tune settings as you like.

applying random adjustment settings

The five groups of settings start off with the detail tab.

One of the longer pop-up tips shown.

main detail adjustment settings panel

I'll show some of the fine tuning with this photograph of the Leicestershire countryside, taken one Autumn afternoon.

It's rather flat, since the sun was behind a bank of cloud. When it appeared about 10 minutes later, the broken patches of sun across the landscape gave a much more interesting look.

source image for adjustment

However, on some jobs, I don't have the luxury of waiting for perfect lighting - what can Topaz detail do for me?

A brighter 'Architectural Detail' setting - better, but far too much fine detail in the sky.

higher levels of detail enhancement

The 'Blue Sky II' setting- not bad, but just too garish, I'm not making a Windows desktop image.

blue sky setting boosts saturation

The 'Blue Sky I' setting looks better.

I'd perhaps turn the sky down a bit more for my personal tastes (blending this version with the original, after I've produced it), but it's the sort of enhancement that might work in some of my architectural and construction photography, where I've not had the opportunity to time the shoot with optimal weather.

You can see the actual 'detail' settings that this plugin uses at the right

before and after views of adjustments

Minor adjustments can sometimes make quite a difference, such as here where I've pushed up the 'Fine Detail' sliders a bit further.

adding more fine detail enhancement

The detail adjustments can be applied to the whole tonal range of the image ('Overall')

Move you mouse over the image to see adjustments. This view is at quite low magnification, so do zoom in to 100% before finishing your work in the plugin, since some adjustments only really show up when zoomed in.

minor adjustments compared

You can turn off any of the 5 settings categories, such as here where I've hidden the detail part.

Mouse over the image to see tone and colour adjustments only - note that some of these may be quite subtle.

different aspects of image adjustment turned on and off

In this rainy view, the adjustment is in the shadows. The 'Overall' settings are unaltered, but mouse over the image to see the 'Shadow' settings. Used with care, this ability to affect only some areas of an image is very powerful.

separation of tonal areas for contrast enhancement

Other adjustments

The 'Detail' adjustments are where the real processing goes on, but don't neglect the overall global tonal adjustments.

Whilst I might adjust these settings outside of the plugin, in Photoshop, I appreciate that others might find it useful to do them here.

tone adjustment panel

Although there are colour controls in the 'Tone' section, it's probably better to use the colour controls to warm/cool and image, and adjust vibrance/saturation.

The deblur option is a general sharpening option, with the ability to turn down some aspects of the processing, to remove sharpening artefacts.

sharpening controls

Once again, a feature I'd personally use elsewhere in a more selective manner, but good for quickly enhancing the sharpness of images.

The example below shows how the sharpening can enhance noise (in the water) and shows sharpening artefacts (bottom of head). Mouse over the image to see these artefacts softened.

suppression of sharpening artefacts

Masking

The effects you are applying to your image can be masked off, so they are only applied to parts of the image. The control over masking is quite subtle, and well worth looking at if you can't do the masking elsewhere.

In this simple example I'm painting out the filter, with an effect mask (brush outline shown). The white area shows where the effect is applied.

Move your mouse over the area to see what happens to the mask and how the filter is being applied to the original image (the softer part that 'shows through'.

masking used to control plugin effects

Conclusions

The contrast enhancement options under the 'Detail' tab are very effective, and give excellent fine control over processing.

It's possible to create quite strong adjustments without too obvious artefacts, although as with any localised contrast enhancement technique, it's worth checking carefully at a range of image scales.

The remaining options are all ones I -might- look to do elsewhere, but do remember that I use Photoshop most days, so have wide range of tools and techniques available to me.

There are many applications supporting this plugin that don't have such flexibility, so it may well be best doing the adjustments in one place.

When I'm using Topaz plugins, I usually create a duplicate layer first to work on, then apply the plugin.

The layer now contains the processed image, which I can mask or use in whatever way I want to achieve my desired effects. It would be nice to have the option to do this automatically.

The plugin does allow you to apply multiple instances of filtering to an image, but I found this rather complex and easy to get lost as to where I was in the process.

If you're not using a more complex editor to run this plugin, then do look further into the various tutorials and guides to see what can be done.

As a working commercial photographer it's a great tool for getting a bit more out of images where I've not had the chance to get absolutely optimal lighting. Not every project has the option (or budget) to return to a location multiple times to get everything spot-on, particularly given the UK weather.

The software takes a while to analyse large images when opening them and will remember previous settings, although, if you find a setting you like, then it's always worth saving it as a preset, such as my slightly turned down version of the 'Blue Sky I' preset.

There is a fully functional 30 day demo version of the software that is available.
