I purchased a bottle of Highland Brewing's 20th Anniversary Scotch Ale after trying it at Blue Mountain Pizza and Brew Pub. It's extremely smooth for the style and I can't wait to get another one. For this photo I went out to our wood shed and used some old tin roof as a backdrop. I needed a little extra fill light so I broke out my handy iPhone flash light.
Highland Brewing Co. Scotch AleiPhone 5 flash used as rim light. I grabbed a tulip glass from the cabinet and headed to the wood shed to get a rustic picture. It was extremely muggy and getting late in the evening so there was a lot of condensation on the bottle and glass. I was using my 135mm lens at 2.8 and had bumped the ISO up to 1600 and I still couldn't get a decent shot because I didn't have my tripod.
I needed more light but I hadn't brought and flashes with me. I did have my iPhone with me however. Improvising is a big part of my workflow in photography. You can see the difference in the photo on the left vs the photo on the right. No fill light or rim light.
The image to the left has better definition and the beer bottle stands out more because the background is brighter as well as the bottle having a rim light to outline the shape of the bottle.
In hind sight I should have gone out to take the photo earlier than dusk but thanks to my dslr I was able to achieve a decent image. At this light level it would have been too dark for a cell phone.
You can achieve great images by using a cell phone flash as fill light. If you have a couple friends who are willing to let you borrow their phones at the bar you can take your #beertography to the next level even using your cell phone.
