Oh....sad you are not going to make an entry. Don't you like lentils? I've often entered recipes which are not to my taste - for example I never eat anything sweet (except for the plainest of biscuits very occasionally) but it hasn't stopped me cooking such things. There are many different types of lentils and it is surprising what you can do with them. Puy lentils, for example are a gourmet delicacy! Confit duck with Puy lentils, for example?
As for the camera... I have been using a Fuji Finepx S2500HD which came with a fixed lens (18x optical zoom). But I managed to leave it in Saffron Walden when I visited my friend! As he has gone abroad he can't post it back... so I've purloined my partner's camera, which is a much better camera as you can change lenses and it has optional manual operation which I prefer (particularly for focussing). When photographing food its crucial to get the right parts in focus and the auto-focus sometimes gets it wrong! So the camera I've been using in the last week is a Pentax Digital SLR K-x and the lens is a Pentax DA L 18-55 mm. I think the most important thing (apart from composition) is to get the lighting correct. I'm using daylight as much as possible as I think it really does give the best results. I have some little LED lights that I sometimes use to make hi-lights.
One of the main challenges I find is how to make dishes look appetising. There is a tendency for a lot of recipes (particularly some cakes, biscuits, casseroles and stews to look, well, brown! I spend quite a lot of time arranging the food, garnishes and any props carefully. I don't just snap it as it comes out of the oven! In fact, I generally cook something one day and photograph it the next day - so I can catch the best light. This will get easier as the days grow longer. Its very funny though because my family see something I've cooked and now say 'Can I eat that or are you saving it to photograph!'.
