Sunburn, deficiency or something else?

We've had hot, sunny days this past week.  I'm watering daily, sometimes twice and noticed these pale patches on several tomatoes.  The plant seems fine otherwise.  Any ideas what it is?

    I'd guess it's had a bit too much sun as the yellowing is all at the top of the plant. It should be able to cope and sort itself out over the next few days.
    Yellowing can be a sign of nitrogen deficiency, but I don't think that's the problem your plants have unless the yellowing gets worse. In which case give it a little feed.
    I've got quite a few raspberries that are half red and the side facing the sun is white from sunburn...

    One of mine did that last year for no apparent reason. It cropped fine.
