Maximum Filter In Photoshop

How To Use Maximum Filter In Photoshop Tutorial (youtube)

Where ?

Where can you find the Photoshop maximum filter ? It can be found in the filter command and others category

Basics

It can add a subtle change to an image as well as a total blurriness of an image. You can use the effect to modify brushes, shapes, layers etc. Create all kinds of spark effects or total white out of an image. It spreads the white and choke the black (according to the Adobe site) but as with many effects, it can do a lot more than that. There are not many options though, radius and preserve (squareness and roundness). The higher the setting, the slower the application. Personally, I always prefer the roundness option to the squareness as the results seem to be less crude.

brushes

You can use the effect with brush strokes. Select the brush tool and apply brush strokes in black (using a default stroke and on a white background). Apply the effect with a decent sized radius, though the actual results depends on the radius and what you want. If you have applied a number of brush strokes with a setting of 60px then it probably is not a good idea to set the radius to 60px as you will just end up with white. Set the radius to 15px and then re-apply a few times (they can be applied multiple times with more subtle changes than a brutal one click effect). You will then end up with a much lighter pencil like drawing than than the original sketch, a bit like the effect of reducing a large comic page to a smaller actual comic.

type

You can use the effect with type to create thin black type or perhaps faded black type (or whatever color the type has been set to). Such as applying it to the type where the the characters has been reduced to the point where the ink in the typewriter is very uneven and clearly needs a new ribbon in a short while. Say you have a paragraph or page filled with type with a bold typeface, you can apply the max to that to thin the type - the actual thinning depends on the radius. You can simply flatten the type or use the type as a smart object / converted layer via the smart object command. You can create all kinds of interesting visual effects with type by combining the effect and Gaussian blur and the apply it again to create type that looks as expected but certainly is not. As the type is a layer / smart object, it can be duplicated along with the smart effects and then applied on top of each other using blending modes. If you change the color of the type to white, the result is the same with a choking of the white (which does seems odd).

custom shapes

You can use the effect with custom shapes to thin any of the shape designs. As the custom shape can be converted into a smart object, the effect's thinning can be varied. The result on the custom shapes depends on the shape, some shapes such as an Illustration / sketched shape will be reduced and parts of the illustration will just vanish. If you are using the max with something like a circle shape then you will just see an overall reduction in the vector design.

Others

You can use the powerful tool with other in combo. You can create some truly amazing twirl designs by combining the effect with the twirl and many other great combinations are possible. You can also with the new neural effects as well as colorize to create some truly weird and wonderful designs.

masks

You can create a layer and add a mask via the layer mask command in the layers menu and select the reveal all command. Go to the layers panel and select the layer mask (to the right of the layer) and then add some shapes in black as a pixel design or perhaps some brush strokes. You can then go to the filter menu and apply the effect to the mask and the result will be more of the actual layer. It should be noted here that the effect is destructive and is not a smart, so any applications will change the selected artwork. The mask can also be useful with creating a beveled design and the effect will be useful in modifying the overall hole or bumps in the image

Channels

Add a shape or image or type to a document. You can also use the effect with channels. Go to the channel panel and select the red channel. Select the effect and set the radius to 20px say. You can then apply a different set of settings to the green channel and then apply a different effect to the blue channel. You can then re-combine them all again via the round button at the top of the channels panel. Go to the green channel and then re-run it but this time using 10px and then the blue etc. You can re-apply it multiple times to the same channel. Go back to the RGB (or CMYK etc) image. You will now see a colorful edge around the design.

images

This really depends on the image, but I have always found the effect with the roundness setting generates an unusual sparkly glow with highlights and gives the image a really surreal look. The squareness option is never as pleasing but it has a use in creating very large blocks of color across an image which can be blended with the original image using the fade command. If you set the roundness / radius setting to too higher a value then it will be slow to process and will result in a totally white image but it does work well if you use an image with channels and the max effect and set one of the channels to a very high value. A low value of the effect often just makes a person look a little sweaty as if they are under hot lights. The effect can be used to create some interesting effects when combined with the image menu adjustments such as black and white to create an unusual glistening effect with people etc

fade

You can fade the effect, you have just applied it but fading brings a lot more options where the effect can be blending with the original image and used with difference, lighten etc as well as opacity to create all kinds of weird and wonderful smeary effect.

Smart objects

You can use the effect with the powerful smart object feature, convert it via the layer menu and smart objects and convert and once you have converted it, the effect can be added as normal but now you can change it any point, it is no longer a destructive effect. You can add multiple smart effects as well and they can all be edited at a later point by double clicking the entries and they also have their own blend option for even more powerful combinations.

actions

I love actions, they can be used to record the action of the effect and all the settings along with combining it with adjustments and also other effects added to the work and the action means that you can re-play the effect over and over to combine multiple effects.

selections

You can use it with the entire image but sometimes you just want the effect to be added to a small part of the image or perhaps a subject via the select menu and subject. You can then apply the effect to that selection and sometimes an even better option is to apply it to the inverted selection or perhaps apply to both but with different settings to create some truly wonderful imagery

Combine the max and min.

All kinds of weird and wonderful effects can be generated just by using a combination of these two, one adding a sparkle to the image and the other darkening it again and this can be repeated a number of times to create unusual imagery.

Noise effect

You can use the effect with noise and noise can be added in a number of ways such as via the gallery effects and via the noise category and also via the blur gallery (and there are probably a few more). You can generate the noise and then use it with the effect. You can use it multiple times to create all kinds of unusual sparkly noise effect.
