Pro’s killer kit

Depth of field cal­cu­la­tor

NPhoto - - The Art Of Weddings -

Kate says… When you’re try­ing to fig­ure out how much of a de­tail or por­trait you’ll get in fo­cus at a par­tic­u­lar aper­ture, a depth of field cal­cu­la­tor (such as dof­sim­u­la­ can give you a good idea of whether you need to go smaller or big­ger with aper­ture. Just in­put fo­cal length, aper­ture and dis­tance from the sub­ject, and the cal­cu­la­tor will tell you how wide a sliver of the sub­ject will be in fo­cus. If, say, you want both eyes sharp in a por­trait, and they’re at dif­fer­ent dis­tances from your Nikon be­cause your sub­ject is at an an­gle, a depth of field of 10cm will re­as­sure you that both should be sharp in your fi­nal im­age.
