UsingPhotProc

When PhotProc loads, you are presented with the main editing page:

There is a menu button in the bottom left-hand corner. Press that to open up the main menu:

Press "load" to load an image. That's the obvious bit! It takes a while to load thumbnails in the background, so you may need to be patient, especially if your photos are very high resolution. Until a photo thumbnail has been loaded, you get to see the file name in a grey box.

If you want to see your pictures full-screen, so you can choose the right one more easily, then press on the "grid" button. This switches between "grid" and "gallery" views.

Press on a photo to load it. You will get back to the main menu page. If you want to load an image from a specific place in the file system of your device, then press "File" which opens up a file dialog instead.

To edit an image, press "Edit" from the main menu. You can then select from several classes of image-processing.

You can make the edit page disappear so you can see your photo full-screen by pressing the down arrow in the bottom right-hand corner. To bring up the last edit page you had open, press the up arrow in the bottom right-hand corner. To go back to the main file page, press the menu button in the bottom left hand corner again.

The main edit page has several options:

• File: This takes you back to the file open page
• View: Preview/Original: This switches between showing you your original image or the preview
• Reset: This resets all editing parameters to the default. There is no way of undoing this, sorry!
• Levels: This lets you do basic editing for brightness, exposure, saturation etc.
• Colours: This lets you do more advanced colour editing, such as highlighting certain colours or correcting for bad lighting colouring.
• Enhance: This lets you sharpen or de-noise your image.
• Dynamic: This does more complex filters for handling dynamic range and contrast. It can be used to darken shaded areas of images or emphasize details.
• Crop: This lets you crop your image. You get some blue borders you can use to change the crop rectangle
• Info: This shows you information about your photo, including resolution
• Resize: By default, PhotProc outputs photos at 2MP resolution, which is good for social networking and quickly processing an image. You can change this all the way up to the full original resolution (even 41MP!)
• Advanced: You should probably ignore this unless you are a developer and want to write your own filters.

Pressing one of the above buttons gets you to a full edit page. The editor pages are often larger than the screen, so you should move the page around to see all of the features. The arrow button in the bottom right hand corner makes the current page disappear and reappear.

You can zoom in, out and around your photos using 2 fingers, or double-tapping on the photo.

When you edit a parameters, it will show you a preview, which takes a bit of time to update. It will not actually save or modify the image, it only ever shows you a preview of what the image will look like when it's fully-processed.

You will see some text in the top left showing what the program is currently doing. It might be "Ready", meaning it's waiting for something to happen, or it might be loading a new section of the preview, or re-processing the preview.

When you have got something you like, go back to the main menu and click "Save". This is when the actual full-resolution processing is done, so for very high-resolution images, this can take several minutes. There's a "cancel" button, which cancels the currently-processing job.

You will still see the progress of the image-processing in the top left-hand corner. You can actually have up to 8 image-processing jobs on the go at any one time. There is a "Jobs" button that appears on the main menu once you have jobs saving that lets you see the image processing jobs and that also lets you cancel the jobs.

You can only see the "Exit" button on the main page (keep pressing "back" until you get there) when all photo-processing jobs have finished.
