Geló Tutorial 14 - Breaking up images with shapes by James Moore


Using coloured shapes within Geló, you can great all sorts of effects. With a combination of blend modes, you can create multiple effects in areas that can break images up, and add new shapes as the result of overlaps. In this tutorial we'll look at this technique, of blending two shapes together with different blend modes. Let's start with an image that was initially run through Simply B&W. This allows us to increase contrast, remove colour and make the image more graphic in its composition.

After loading in your selected image, select a bright, strong hue. Reds, strong green, vibrant blue or yellows will work best. Mid tone colours may not produce the results here but, as always it's good to experiment.

Using a square overlay, we'll scale this up to full width of the image, and position roughly halfway across the image. Top or bottom it won't matter, and of course chose the composition that best suits your image. Render this over the image with an over blend mode and save.

In subsequent versions of Geló you will be able to add multiple shapes in one edit. However in this first (version 1.0) this isn't yet available.

Reload your saved image back into Geló (with the shape added) and select the same swatch you previously applied. This is best to try first as the colour is exactly the same, and will be positioned in the same area of the image. Reposition this shape so that an area of the gel overlays the already coloured part of the image. In essence so the two gels overlap.

Apply this new position and select the add blend mode. You will notice in the image above that the blacks in the top area are coloured using this blend mode, and the lower area of the image, the over blend mode has affected the lighter areas, colouring them red.

Where the two effects meets, and overlap you notice that each effect cancels each other out - in this case with a thinner red stripe. This is the result of compound blends that have an effect on different parts of the image (ie light and dark)

Save your image with this new combined blending.

If you wish, you can add further effects such as gradients, other shapes to make your image different. In this example we've added a blue overlay just to deepend the red and take away the stark colour from the increased contrast.

Try it yourself with shapes at angles, maybe similar colours for more subtle effects (such as a deep red with a burnt orange) or mixed with gradients.

Here are a few other examples...

Geló Tutorial #13 - Using multiple apps and gradients for atmosphere by James Moore

Using multiple apps and gradients for atmosphere

Dusk in winter-time gives us loads of options for creating atmospheric images. Bare trees, icy cool skies and contrasty black sillhouettes as the sun creeps below the horizon. Using a combination of elements in this image, there were a series of interesting shapes and textures against a flat wintry sky. To balance this out, it's split halfway with a solid dark shaded area, blacked out by a combination of low light in shade, yet enough light in the sky. The human eye would see more detail in the shadow, but the camera punches this out with a brighter sky.

Taking this shot, and running through Bleach Bypass this gives a more pleasing aesthetic. Vignettes in the sky gives depth, and 'frames' the shot a bit better up top. It also adds punch to the sky with heightened contrast which is characteristic of the Bleach Bypass effect.

Saving out this image it is then loaded into Geló (PhotoAppLink will be coming soon for Geló so you can send this directly from Bleach Bypass without the need to save)

Using a dusky purple gradient in the Overlay mode adds colour to the sky, and retains the blackness. It is not a true representation of the image in reality, but it adds atmosphere and a bit of colour. Of course it's all subjective to tastes, and other colours could work better, if indeed colour is desired or needed at all. Deep reds of intense purples could work well, but you could try an abstract colour like a green or brown colour.

Saving this out of Geló the image is then imported into Instagram. Many of Insta's filters are great on their own to create those retro effects, but they can be used to great effect to augment other apps filters and styles.

Certain filters like 'Mayfair' for instance further enhance the saturation, and make the highlights pop.

It's a nice final element in the workflow to sharing, and it shows a subtle way of using multiple apps to add something extra to an image.

Geló Tutorial #12 - Cinematic film look by James Moore


We've all seen the musty, cinematic effect in movies; classics like Rear Window, Taxi Driver, The Godfather, Bladerunner, the list goes on... They're all shot in film which 'adds' another layer to the visuals. There are the murky blue blacks, that soft greenish tint and muted highlights. It all evens out but there's contrast, rich colour.

This simple tutorial shows you how you can achieve a similar effect in Geló. It wont work for all settings, and the values shown don't necessarily apply to your own images. But it gives you an idea.

Once we load the image in, lets add a degree of colour and contrast to the shadows. Using a dark blue (eg. R:0, G:14, B:27, A:69) with HIGH contrast over a COLOUR image. Using TINT blend mode, this will increase contrast, yet retain highlights adding colour in darker areas.

Save the image and reload back in.

Next we will add a pale beige colour (yes beige) which 'softens' those highlights and gives the image an all-over filmic look. We've used the values (R:194, G:169, B:118, A:59) in this example but again tweak until it suits. Blend this OVER the COLOUR image with STANDARD contrast.

Save this image and then reload into Geló from the Camera Roll.

Next we'll add a deep green tint (R:60, G:79, B:35, A:61) over the COLOUR image with STANDARD contrast. This gives an added greenish tint to mid-tone shadows and the edges of highlights.

Overall, the depths of shadow are increased, colour saturation is added and the image has a more cinematic feel to it. More akin to the 35mm films used in the 70s and 80s than digitally mastered films in recent years.

Try it for yourself, use purples and blues instead of greens; try daytime scenes for cinematic impact.

Geló Tutorial #11 - Cross Processed Look by James Moore


Cross processing had been made popular thanks to the lomography but it is a photographic technique that has been around for quite some time. Cross processing (also known as Xpro) involves processing a photographic film, usually slide file in the incorrect chemicals. A commonly used formula for Xpro is the processing of E6 (slide film) in C41 (colour negative) chemistry. Resulting images have unnatural colours and high contrast and the results of cross processing vary depending on the chemicals and film used. Certain films take on a greenish tinge, while others will turn red or purple.

Depending on your taste, you can replicate this using Geló, and a simple bit of research will help you find colours that you may wish to replicate.

In this image we have taken a classic Dodge Charger shot on a sunny day. The subject lends itself well to cross process, being the epitome of retro and retro style - which cross process is perfectly suited to. Similarly it works well with portraits or other scenes.

After loading the image we will add a dark green gel which is added with a SOLID gel using a TINT blend mode over the image. This darkens the shadows and intensifies the colours. Keep the image in COLOUR and with NORMAL contrast. You may need to deviate from this dependent on your own shot but this works better in this image.

Save the image with the gel, and then reload this newly processed image back in to Geló. Select a lighter green, and overlay using SOLID gel mode with an OVER blend mode and keep the image mode as COLOUR.

Using the edit sliders, take the alpha for this new solid overlay down to between 40% and 50%; so as to add a film of muted green colour.

Finally, bump the contrast of this image up by setting the contrast mode to HIGH.

Save your image which now has a greenish cast similar to a cross processed image.

Of course, look around on the internet for other examples of cross processing and try to replicate using the colours and gels within Geló
