  • A band-pass filter is a device that passes frequencies within a certain range and rejects (attenuates) frequencies outside that range. An example of an analogue electronic band-pass filter is an RLC circuit (a resistor–inductor–capacitor circuit).
  • A notably happy or successful moment
  • a lofty level or position or degree; "summer temperatures reached an all-time high"
  • at a great altitude; "he climbed high on the ladder"
  • A high-frequency sound or musical note
  • greater than normal in degree or intensity or amount; "a high temperature"; "a high price"; "the high point of his career"; "high risks"; "has high hopes"; "the river is high"; "he has a high opinion of himself"
  • A high point, level, or figure

Labour Day... Everyday.
Friday early morning, the weekend in the Middle East, as most people are enjoying but for this man it's just another working day. Well, he is not alone. -------------------------- Workflow ---------------------------------------- There are 3 steps in this workflow. But before you start, please consider the following: the photo must be 16bit RAW or uncompressed so that it contains as much (hidden) details as possible. It is also good to under expose the image a little because it is easier to lighten dark areas than to recover burned highlights. Step 1 - Recovering highlight areas and opening dark areas. I used Adobe Photoshop Lightroom for this by adjusting “Recovery” and “Fill Light”. Then from the “Photo” menu select “Edit in”, then “Edit in Adobe Photoshop…” to send it to Adobe Photoshop. Alternatively if you do not have Adobe Photoshop Lightroom, you can also achieve the same result using Photoshop. Open the photo in Photoshop then select "Shadow/Highlight" from the "Adjustment" menu (note: non-"CS" versions of Photoshop does not have this feature). This will give an effect similar to a photo or image which is a combination of 2 or 3 exposures. Step 2 - Local contrast enhancement using "Dodge" & "Burn" tool on Photoshop. But first, what is Local Contrast Enhancement or LCE? Think for example of the moon, the global contrast is the lit and unlit area that creates the shapes while the local contrasts are the craters. In simple term, local contrast is the detail. There are ways of enhancing local contrast in Adobe Photoshop and the most common is the USM or unsharp mask. Another method is applying a “high pass” filter on a duplicate overlay layer. In this workflow, I used "Dodge" & "Burn" tools to enhance details manually. The trick is to identify what part of the photo needs to be dodged or burned, so it is important to have a very good understanding of visual elements. Be aware of the emphasis, what part(s) of the photo you want the viewer to see clearly and what’s not. Once you know what are the areas that need to be dodged or burned use a brush size and shape that matches the size and texture. Also use minimal pressure, around 5%-15% and apply repeatedly rather than applying once with a greater pressure, this will allow you to constantly evaluate the result. The combination of Step1 and Step2 is similar to Tone mapping in HDR applications. Step 3 – Tinting (optional) Applying tint gives the photo a unique mood and feel. There are different ways also of changing the tint. We can use “Photo filter” adjustment layer, we can also use “Color Balance”, “Curve”, “Level”, “Selective Color”, a “Solid Color” overlay, etc. For this workflow, I used the most common one – “Hue/Saturation”. In “Edit” under “Hue/Saturation change “Master” to “Reds” move the slider to the right until the red areas of the image become yellowish, change “Reds” to “Yellows” move the slider to the left until the yellow areas become golden yellow, you may also reduce saturation by dragging the “Saturation” slider to the left. This is just an idea of how to use the options of achieving the effect that we want. Photos are not the same, so what works for this photo may not work for yours therefore you need to experiment, experiment and experiment.

This is a Merge between a dave hill effect and a well twist of my version of it =D Ill point out the tools i used and filters i used in this Edit *Hope its usefull* - ?If a Close up Windlight is used then you prolly wouldnt need to use the Brightness&Contras ?Else,Always better to Adjust the level of brightness depending on the skin colour of the person ?Layers are your Best Friend Use Different Layers when applying Different Filters and always keep a Clean Layer as a back up. Use shortcuts CTRL+E to merge the layers and CTRL+J to duplicate a layer.Shortcuts always make the edits quick =D ?Once a new layer is duplicated i Used for this effect HIGH PASS and then I Changed the type of layer from normal to vivid light.Play with the Opacity Level lowering it would be best for a Sl Edit Picture.Merged this layer to the layer below. ?To achieve this effect i actually duplicated another layer and used HIGH PASS again this time with the level slighty higher then before and i changed the type of layer from normal to Colour. This gives a soft effect to the image very nice to the skin.Again play with the opacity level to your liking and merge down this layer. XNext step would be to adding a Gaussian blur effect to this image not to blurry around 4.0-4.5 would do.Once the Blur is added add a Mask Layer to the layer once you do that Fill the layer with 50% grey Shortcute key: Shift+F5. Once the 50% grey Fills the trick is to use a brush tool brush of the parts you want to stand out for example the eyes the hair the lips.This gives a almost like pop out effect :D ?Merge Down the layer CTRL+E and CTRL+J to duplicate.Convert the layer to a smart object and add filter Shapern-Unsharp Mask.Adjust opacity to your liking. And now Add Filter Noise-Reduce Noise to your liking.Merge down the layer CTRL+E ? YOUR BEST FRIENDS HAS TO BE THIS STEPS: DODGE & BURN TOOLS. The dodge tool gives you a chance to add brightness to parts of the image you want i use it almost always on the eyes giving it the glow. And the Burn tool lets you to darken part of the image you want you can use it add shadows on the skin makes it look more natural =) ? Basically youre done! *Yaaayy* For second life Imaging Using the Liquify tool is like a MUST! To fix every glitch there is.I usually use the liquify tool before i edit anything else on a pic =D I hope this gave a basic idea to how this picture was edited *huggies* Model: Sluuge Resident Photographer:Kavi Aldrin
