Pentax Ricoh have posted a firmware update for the Pentax Q compact system camera. Version 1.12 corrects a bug related to the Smart Effect, "Tone Expansion." This effect is supposed to produce a dramatic, "quasi-HDR" image but users who have updated their camera firmware to version 1.11 when that update came out have found that the effect was no longer applied. This issue is resolved in version 1.12, which you can download from the website below.
