Instructions

Superimpose can primarily be used for three purposes...

1.Superimpose or Juxtapose:

You can remove the surroundings of an object in a photo and replace that removed part with a different background image. Here are two example videos...

2.Blend texture or border:

You can combine a normal photograph with a textured or pattern border image with different blending modes to give the photo an artistic look. Here is an example...

3.Create a double exposure photo:You can combine two photos, one over another, with certain transparency to make a double exposure photo...

Application sections

There are four major steps involved in creating a superimposed photo using this application. Each of the step is represented in a section the bottom tab bar.

Home: In the Home section you can load the photos and save the resulting superimposed photo or upload them into Facebook or Twitter. You can also save the masked image into it's internal mask library. You can load masked images previously saved into the masked library. Using the information button, you can reach the information page and to the instruction section. Use the delete button to delete the current session.

Transform: Transform section is for panning, sizing and rotating the foreground image and to adjust it's transparency and blending mode etc. You can also flip the foreground image horizontally or vertically. The foreground and background images can be swapped using the swap button. The merge button can be used to merge both the images together so that you can load one more foreground image on top of it. Use the reset button to bring the foreground in the middle of the background, and fit button to scale the foreground to the background.

You can double tap on the image to fit the foreground to the background, without losing the aspect ratio of the foreground image. To keep the aspect ratio fixed, press the aspect ration lock button. And to snap the foreground image into the edges and middle of the background, press the snap to edge (magnet) button.

Mask:This section is one of the most important section where you can remove unwanted portion of the foreground image. There are several masking tools available which are described in the end of this help section. Use the view mask button to view only the foreground masked image. You can undo and redo your masking actions. Use the invert button to invert the mask. Clear button can be used to remove the entire mask. The blur mask is very useful if you want to smoothen the edges of the mask that you have created on the image. Note that in mask section the blending mode is always changed to “Normal” for a better view of the foreground image while masking.

Filters:In this section, you can apply (Hue, Saturation), (Exposure, Brightness, Contrast), Color Balance and Blur filters on both background and foreground images. Use the background and foreground buttons to decide which image to apply the filter on. If you press the reset button when no filter is selected, all the filter parameters will be reset. But if you have a filter selected when you press the reset button, only that particular filter will be reset.

Masking tools

1) Eraser :This is mask eraser brush. You can adjust the brush radius and smoothness in the settings section. On iPad, to get the settings, press on the settings button on to top right or press on the mask tool button and hold it.

2)Magic Wand :Using the magic wand you can mask all the similar color pixels surrounding the point where you touch. For example if you want to mask out the entire sky on an image, just touch the sky and the entire sky should get masked. You can adjust the threshold to control how much variation in color the tool should consider to be same color. The mask edge mode provides two options. Solid, where the mask edges remains solid; and feathered, where the masking strength is proportional to the similarity of the masked pixels's color to the color of the pixel that you clicked.

3)Color Range : Similar to Magic Wand, but instead of selecting only the connected pixels, it selects all the pixels in the photo that matches in color to the color of the pixel that you touch. Same settings as Magic Wand applies here also. This masking tool generates real time masking preview while you move your touch around the photo. Release the touch once the tool is masking the desired colors.

4)Brush :You can mask using this brush as well. In settings you can adjust the radius and the smoothness of the brush.

5)Lasso :By drawing a freehand lasso, you can mask the entire inside (or the outside) of the lasso loop. In settings you can choose the smoothen amount of the lasso mask's edge. In settings you can also make the lasso so that it masks outside the loop instead of the inside.

6)Polygon :You can create a polygon by tapping on each vertex of the polygon and then accept the polygon by double tapping on it. In settings you can also make the polygon so that it masks outside the loop instead of the inside.

7)Rectangle:Draw a rectangle to mask rectangular area. Once done double tap the image to accept the mask. You can adjust the smoothness of the mask edge in the settings.

8)Ellipse :Similar to Rectangle mask tool, but you can use this one to draw ellipse instead of rectangle.

9)Linear Gradient :Drag and draw a line, and this tool will create a gradient of mask for you. Double tap on the screen once you are satisfied with the mask.

10)Bi-Linear Gradient :Same as linear gradient, but the gradient created is bi-linear.

11)Radial Gradient :Same as linear gradient, but the gradient created is radial.
