Photo editing definitely isn't my forte, so I like to keep things simple when it comes to playing around with the images on my blog. I'm lucky enough to own a MacBook and a (pretty basic) adobe suite, although I in no way think that they're vital tools for producing great photography.
For the most part I use Adobe Lightroom to brighten and clarify my photographs. The exposure, white and black sliders are my most used and I tend to find that I can get a good amount of light and contrast in my images from these alone. Depending on the shot taken, I may also use the noise reduction slider to perfect the image and leave more of a soft-focus finish. Although many of the tools are also available on Photoshop, I tend to find that Lightroom is far easier to use; especially for techno-phobes like myself.
At the moment I'm using Squarespace as my blog host, a platform that I find particularly helpful when it comes to making the most of my photography. Depending on the theme used, Squarespace automatically stretch the image to fit the width of the blog without compromising on quality. The images also appear on my blog exactly how they do when I save them on Lightroom; a god send for any of us with experience of Blogger. Even so, when I did use Blogger I found it helpful to upload my images to an external hosting site (Flickr or Photobucket) before adding the images to the post via HTML. Blogger have a tendency to alter the image upon upload, so for me this was the only way to ensure that things appeared as I wanted them to. Again, I then resized the photos using HTML - something that is really simple once you get the hang of it and determine the perfect image size for your blog.
No matter what your tools, there are plenty of ways to get the most from your blog photography. Many of my favourite blogs admit to taking images on their phones and there are so many ways to edit them via built in tools and/or additional apps, too. I use VSCO Cam for my Instagram photos, but there's no reason you can't play around with the software for your main blog photos, too. Once edited, they can easily be saved to your camera roll in order to be uploaded to your site. There are also a whole host of add-on lenses for your phone that will increase the image quality before you even begin editing. Wide angle and macro lenses for your phone are now easy to find and can be a massive help when it comes to optimising the lighting in your photos.
