Sunny days are generally not great for photography. The harsh light can make it very difficult to create good photographs but we should learn to use whatever conditions are available to our best use. There are lots of techniques and ideas you can do to help in these conditions.
1 - Use a prime lens - the lack of zoom just gives one less variable to worry about when composing your shots... to be honest I prefer primes at the best of times but when the conditions are not ideal (for my needs) a prime is a definite.
2 - Bung on a polarizer - this will kill a lot of the reflections that ruin shots.
3 - Lower expectations - accept the conditions are not your friend here - I'm hardly going to get beautiful soft light at 2pm when the sun is blazing... this can take an unusually long time for us photographers to accept!
4 - Experiment! - I try and use the conditions to my advantage; try out unusal compositions, or including shadows and reflections. Strong graphical elements can really stand out if you utilise strong sunlight
5 - Plan for later - It's a lovely day, so if I can't get the shot I want now... I make a note and come back later. The Tyre Distributor image above is a prime example of this. I like this shot but I know I can work it better on a cloudier day. I have a 'Locations' folder in Lightroom where I squirrel away ideas I have to return to at a later date
