  • Everything you wanted to know about Banding and were afraid to ask

    We’ve all been there: you sit on a picture forever, bored of retouching, and then when you do get around to it strange things start to show up in it. Like odd rings of graduated color. These rings of color are called banding. They are nothing more than tonal breaks but before I explain where […]

  • Hands-on: RAW Power for iOS

    If you’re a Mac-owning photographer, you probably used—or toyed with, or still stubbornly refuse to give up—Apple’s long-abandoned Aperture application for editing photos and managing your image library. The official replacement, Apple Photos, is targeted at a broader audience and lacks many of the Raw-editing features Aperture was built for.

    Now, former Aperture development lead Nik Bhatt, via his company Gentlemen Coders, has created RAW Power, a Raw image editor for Mac and iOS that digs deep into Raw editing and throws in some unique features, too. The just-released iOS version works on the iPhone and iPad, and pairs with the macOS version, which was released in 2016.

    On both platforms, RAW Power operates as a stand-alone app; on the Mac, it's also an editing extension in Apple Photos. If you already use Photos to store your photo library, it can still be your hub.

    RAW Power reads your Photos library directly, including Photos-created special albums for Portrait images, Favorites, and Selfies.

    Raw Boost

    A Raw file is the fullest available expression of the output from the camera's sensor, creating a file with a lot of image data to plumb. Aside from obvious adjustments such as exposure and color, a Raw editor can control aspects specific to the Raw format, such as sharpening and reducing digital noise.

    RAW Power leans on the Raw image support Apple builds into macOS and iOS. That includes reading Raw files from various cameras (because every model, maddeningly, has its own Raw variation, even by the same manufacturer), as well as how the data is interpreted.

    Sometimes that means manually circumventing some adjustments. Apple’s Raw converters apply a Boost setting to Raw photos to add color and punch to what would otherwise be a flat appearance. RAW Power can pull that back or turn it off for more control. A Black Boost slider gives you more latitude when adjusting dark portions of the image. Similarly, you can turn off the Gamut Map, which is a feature that reigns in tones to help prevent the values from going beyond the working color space (Adobe RGB or P3).

    Adjusting a washed-out Raw image using RAW Power on an iPad Pro. Here we're viewing the "before" image by tapping the Show Original button.
    The same Raw image as above, with the Raw Processing settings applied.

    As for other Raw-specific options, RAW Power can also adjust the overall black point, compensate for luma and color noise, apply sharpening and protect detail, and adjust local contrast using a Raw Contrast control.

    For all images, RAW Power offers clipping indicators, both in the histogram and as temporary overlays to see where the brightest and darkest portions have exceeded the image’s tonal and color ranges.

    The Curves feature adjusts each channel (red, green, blue, and the three together), with a couple of options. Normally, curves are applied in Gamma mode: a gamma correction is made to the data before the curve adjustment is made, and then the correction is reversed after the adjustment. As with Boost and Gamut Map, Gamma mode is designed to present a well-rounded result. Switching from Gamma mode to Linear mode removes those guardrails to give more editing latitude. Curves can be applied equally to the combined RGB channels, or, in Luminance mode, using an equation that doesn’t push color casts out of whack.

    Applying a curve in Linear mode initially presents a less saturated version of this image, but it opens the possibility of more specific editing.

    Depth Effect

    The Portrait mode on the iPhone 7 Plus, iPhone 8 Plus, and iPhone X uses the dual cameras on those devices to create a depth map of the scene, identifying objects in the foreground, such as a person’s head, and isolating it by artificially blurring the background. RAW Power can read the depth map and independently edit the shadows and highlights for foreground and background areas the iPhone identified. This works only for Portrait images captured under iOS 11, which saves the depth map with the original image. It can’t change the amount of blurring in the background, however.

    The depth overlay reveals the areas the iPhone cameras identified, with closer objects appearing brighter.
    The Depth Effect adjusts the highlights and shadows of foreground and background areas.

    Round Trip

    RAW Power saves all of its edits non-destructively. When you grant the app permission to modify the image stored in the Photos library, the edits themselves are saved as instructions; the pixels in the original image aren’t changed. The adjustments carry over to iCloud Photo Library to be updated on all your devices. The photo can be reverted to the untouched original at any time in Photos; if you re-open it in RAW Power, all of your adjustments are where you left them.

    RAW Power saves its edits back to the Photos library, with your permission.

    RAW Power is free to use, and includes most of the app’s editing features. The Advanced Adjustment Pack, a one-time $9.99 in-app purchase, unlocks the Curves, Depth Effect, and White Balance tools.

  • How to Clone Yourself – Step by Step Tutorial

    You have probably seen photos on the internet where the same person appears in multiple spots in a single photo. At first sight, you might not have believed it, and later you must have gone berserk looking for ways that effect can be achieved. Well, who does not want that superhero feeling where you can appear in 2-3 different places doing 2-3 different things as well in a single photo.

    Let me tell you, it is not at all complicated or difficult to clone yourself multiple times in a single frame. You can achieve this effect by going through two simple stages, the execution stage (shooting) and the post-processing stage. By the end of this tutorial, I am sure you will be able to create pretty awesome clone photos, feel free to share them in the comments section.

    How to Clone Yourself - Step by Step Tutorial

    Part One – How to Clone Yourself – Execution

    In the execution stage all you need is a:

    • A digital camera
    • A tripod
    • Shutter release remote or use the built-in self-timer

    Step 1:

    Mount your digital camera on a tripod. As you will be taking multiple photos you need to make sure that the frame in each photo remains the same and the camera doesn’t move.

    Step 2:

    Make sure that Manual Mode is selected as you do not want any aperture, shutter speed, or white balance variations in your multiple photos. This is to make sure that all your photos are consistent in exposure, depth of field and color temperature.

    How to Clone Yourself - Step by Step Tutorial

    Step 3:

    Now focus on the point where you will be standing or sitting and switch the focusing mode to Manual as well. This is again to ensure that each photo is consistent in terms of depth of field and sharpness. An important suggestion is to use an aperture which is not too wide, something around f/5.6 – f/8 would be ideal to get good depth of field.

    Step 4:

    Switch on the 10-second timer on your digital camera so that you have enough time to position yourself in the frame and get ready for the photo. If you have one, you can also use a wired/wireless shutter release remote to click photos once you are ready and in position.

    That’s it, now you are ready to take as many photos you as want to by positioning yourself at different spots in the frame.

    How to Clone Yourself - Step by Step Tutorial

    Here you can see the four shots I took. It’s important to take one of just the scene without you in it as well as you’ll need it for the next stage.

    Note: It’s important to take one of just the scene without you in it as well as you’ll need it for the next stage!

    Part Two – How to Clone Yourself – Post-Processing

    Now comes the interesting part of this tutorial where you get to learn how you can clone yourself multiple times in a photo using software such as Adobe Photoshop. Let me take you through a step-by-step explanation of how I achieved this photo.

    Note: you need an image editing software that works with layers to do this. Lightroom cannot do this.

    Step 1:

    Import all the photos into Adobe Photoshop and get them to a single workspace by going to individual photos, pressing CTRL/CMD + A (select all) and again pressing CTRL/CMD + C (copy). Now go to the photo where you want all other photos to be brought together and press CTRL/CMD + V (paste). Do this for all the other photos until you have all the photos in one workspace as layers.

    Make sure the image without you is the bottom layer. If it is not, drag it there now.

    Note: Alternatively you can open Adobe Bridge and find your images. Select all the ones you want to use (CMD+click on each to select more than one) and go to Tools > Photoshop > Load files into Photoshop layers. This will achieve the same thing as copy and pasting each image. If you work in Lightroom you can select them all, right-click and select Open as Layers in PS as well. 

    How to Clone Yourself - Step by Step Tutorial

    Step 2:

    Now add a black layer mask (press and hold ALT and then click on Add vector mask icon as shown in the photo below) in order to start the editing process. Select the Paintbrush tool and make sure that black is selected as the foreground color, and then click once on the mask of the layer you want to work on first.

    Note: Make sure the mask is selected not the layer. See the white bracket corners on the mask? That means it is selected. 

    How to Clone Yourself - Step by Step Tutorial

    Step 3:

    Layer by layer, start painting (at 100% brush opacity)_ over the area where you are located in that frame to make yourself visible in the photo. Do this with all the layers in order to make yourself appear in the photo at multiple spots as shown in the image below.

    How to Clone Yourself - Step by Step Tutorial

    While bringing back one of yourself in the frame, if by mistake you erase your previous photo (your clone) you can bring it back by selecting the foreground color as white and painting back over it on the mask. So basically, painting with black lets you make the elements of the current layer visible, and the white color erases the elements of that current layer if you by mistake overdo it.

    Black reveals – white conceals

    How to Clone Yourself - Step by Step Tutorial

    Finish up

    Once you are done cloning all your photos proof check the final photo carefully, there is a chance that you might have erased a part of one of your clones by accident. Make sure you aren’t missing any toes or limbs.

    So once you are satisfied with the final result, export it and start flaunting it on your social media channels and please share in the comments below.
