Achieve sharp focus at photo capture
Why do some of your images look sharper than others?
Lighting conditions - The image quality of your images can vary even on your own phone. This is mostly affected by lighting conditions. Shooting in bright light conditions provides you with the best chance of capturing a sharp image. This lowers the camera sensitivity and takes a faster image reducing any blur.
File format - Each camera manufacturer automatically applies image sharpening when it is saved in the default JPEG file format. Historically I have perceived the Samsung image to have more vibrant colours and sharper details than what I capture on the iPhone. To completely edit your own image from scratch, you will need to change the file format to RAW or DNG on most phones. On Androids and within the Lightroom app itself you can do this by selecting Pro mode. The iPhone requires a camera replacement app like ProCamera or Camera+2. Personally, I prefer to capture JPEG images because it reduces the amount of basic image editing that I need to apply.
Tack sharp, detailed images look amazing in the right areas of an image. Imagine a sky scene full of soft flat stratus clouds that look like a gloomy, dramatic overcast day. Wouldn't those clouds look weird and unnatural if they were sharpened? We very quickly and subconsciously determine what looks 'wrong' or over sharpened.
If you sharpen images excessively or use the tools incorrectly, it can reveal or increase any existing image noise (grainy white speckles) and create white lines around objects referred to as halos.
How does sharpening work?
Edges in lines or shapes in an image are defined by bright and dark tones coming together. The difference between these tones is referred to as contrast. Increasing the contrast at these edges makes the darks darker and light tones lighter. This is why excessive sharpening can introduce the bright halo effect around edges. Done correctly, sharpening can make these edges appear sharper and more defined.
For example, look at the text below. How much sharper does the black text look on a crisp white background? It is the higher contrast - the larger difference between the colours.
Do you need an Adobe subscription?
No, simply sign up for a free Adobe ID account. You get access to all the sharpening features on a free account. You can download the app on either Google Play or the App Store.
Benefits of using Lightroom mobile app
One of the advantages of using Lightroom to sharpen images is the ability to return and adjust the original adjustments without applying more adjustments after subsequent editing. To explain this non-destructive process, let's explore what destructive means! Imagine sharpening an image, applying some blur and then trying to sharpen a blurred image. Lightroom lets you go back and either delete the blur or re-adjust the sharpening before the blur step.
The main benefits of Lightroom mobile app are the tools available. Let's explore the what, how and when to use each of them in detail. To access the tools, open the image in Lightroom then tap on the Details menu.
An alternative app Snapseed also has a sharpening feature. However, as you will discover Lightroom mobile app has a lot more control.

Number one hidden feature
Even the savviest of Adobe users do not know about this tip. You can impress all your 'big' camera friends with this one! When we make the below adjustments we can zoom in to see the changes, however, it can still be quite difficult to see what is actually happening to the image.
Push the marker along any of the below-mentioned sliders, pause and hold that finger on the marker then hold a second finger anywhere on the screen. Keeping that second finger in place, slide the first finger across the slider and pause for a second to reveal a greyscale version of the image. This can take a little bit of practice. The greyscale removes the distraction of colour. Swipe your finger and pause between previews to see a much clearer view of what each tool is doing.
NOTE: For the Android users, when you hold the screen, you will see a before and after image. This may change by the time you read this article. Fingers crossed!
Lightroom sharpening tools explained:
This is one of the best tools and the amount depends on your image! At 0, the above adjustments are applied to the whole image. As you slide to the right toward 100, only the strongest and most prominent lines in the image will be affected. I typically start at 80.
When you hold a second finger on the screen as you make the adjustment, the areas in black are not affected by the sharpening. White areas are the sharpened areas that apply all the adjustments. This tool allows you to excessively sharpen existing lines and ensure it does not affect smooth areas like interior walls or clouds in landscape images.
