My D7000 some­times seems to aut­o­fo­cus too close when I take land­scapes. How can I avoid this? Jim Berkley, via email

Ja­son says... The most likely cause of those blurry back­grounds is that you’re us­ing multi-point aut­o­fo­cus, and the cam­era is au­to­mat­i­cally se­lect­ing the points that cor­re­spond with the clos­est part(s) of the scene. Try switch­ing to the sin­gle, cen­tral AF point and fo­cus­ing on an ob­ject that’s about a third of the way into the scene. Next, while main­tain­ing a light press on the shut­ter release but­ton to keep the fo­cus set­ting locked, re­com­pose the shot and fi­nally release the shut­ter. It’s also worth switch­ing to aper­ture-pri­or­ity shoot­ing mode and se­lect­ing a fairly nar­row aper­ture of around f/11 to f/16, to in­crease your depth of field. If nec­es­sary, in­crease your ISO set­ting to avoid a slow shut­ter speed, or use a tri­pod.

would What you printer sug­gest for cre­at­ing large­for­mat photo prints at home? Mark Ed­wards, via email

For glossy colour prints at up to 19x13 inches (A3+), Canon’s PIXMA Pro 100S dye-based printer (£275/$400) is un­beat­able. For a mix of colour and mono prints on matte as well as glossy me­dia, the pig­ment­based Canon PIXMA Pro 10S A3+ printer (£380/$700) is a bet­ter op­tion. For sizes up to A2, the Ep­son SC-P800 (£900/$1200) is our cur­rent favourite. An op­tional roll feeder en­ables longer or even panoramic prints (see page 62 for more on get­ting the best out photo prin­ters). Even so, un­less you need to cre­ate prints im­me­di­ately on a reg­u­lar ba­sis, you’re usu­ally bet­ter off us­ing a high-qual­ity on­line lab, like Lox­ley Colour or White­wall, which give you a greater range of larger print sizes to choose from, while also avoid­ing the ex­pen­sive ini­tial out­lay on hard­ware.

I’m af­ter a back­pack to hold a cam­era, four lenses, two flash­guns and var­i­ous

gad­gets – can you rec­om­mend one?

David Frome, via Face­book

Ja­son says... With the amount of kit you want to carry, es­pe­cially con­sid­er­ing that you men­tion a 70-200mm f/2.8, which is pretty large, you’re bet­ter off with a full photo back­pack in­stead of a split photo/day­pack. Cur­rent top choices of man­u­fac­turer in­clude Lowe­pro, Man­frotto, Tam­rac and Van­guard.

It’s rel­a­tively easy to find a back­pack that will hold all your kit, but some may be un­wieldy and quite heavy even when empty. It’s a good idea to ar­range your kit on a ta­ble and fig­ure out what in­ter­nal di­men­sions you need, and what pock­ets you want for gad­gets, then look through man­u­fac­tur­ers’ web­sites. Lowe­pro has a handy ‘bagfinder’ tool to help you choose, at www.lowe­ The Lowe­pro Pro Run­ner BP 350 AW II is an ex­cel­lent, con­ven­tional photo back­pack with plenty of vol­ume for

Pho­to­shop CS6 and Light­room 5 won’t open RAW files from my D810 and D750

un­less I con­vert them to DNG files first.

How can I avoid this ex­tra step?

Steven Spoon, via Face­book

Ja­son says... It can take a while for soft­ware man­u­fac­tur­ers to up­date pro­grams to keep pace with the lat­est kit, but there’s good news for you: Adobe has re­leased Cam­era Raw 8.7, which is avail­able for Pho­to­shop CS6 as well as Pho­to­shop CC. Version 8.6 in­cluded com­pat­i­bil­ity with the Nikon D810, and 8.7 will han­dle files from the Nikon D750. In ad­di­tion, both ver­sions in­clude lens pro­files for a num­ber of the lat­est Nikon-fit lenses. For any­one us­ing ver­sions of Pho­to­shop older than CS6, DNG Con­verter has also been up­dated to version 8.7. Visit­loads/up­dates.html to down­load the up­date you need for your soft­ware.

Should I get a lighter tri­pod or a sturdy mono­pod for shoot­ing land­scapes with a D810? Willem Pre­to­rius, via email

Ja­son says... Switch­ing from alu­minium to car­bon fi­bre will usu­ally save you about 25 to 30 per cent in weight. We’d rec­om­mend Man­frotto’s MT055CXPRO3 and 498RC2 ball head (around £350), which won our Tri­pod of the Year award last is­sue. Com­pared with metal, there’s also a lot to be said for the com­fort of car­bon fi­bre in the cold.

We’d rec­om­mend a tri­pod over a mono­pod for the ex­tra sta­bil­ity and still­ness it’ll give you. You’ll need the least move­ment or vi­bra­tion pos­si­ble to max­imise the D810’s po­ten­tial, with its ul­tra-high res­o­lu­tion sen­sor.

Us­ing multi-point aut­o­fo­cus for land­scapes, you can end up with a su­per-sharp fore­ground, but a blurry back­ground
