Calibrating a laptop

[Perli halpern]

Hi

 

I just calibrated my laptop in my new flat and the results when compared to my prints look very similar.

I'm wondering i it makes sense even though the calibration results show warmer than you mention in the tutorial and the luminance much less than the target.

I have attached screenshots of my results.

[Damien Symonds]

Hi Perli, 59cd/m² sure is low.  Are you sure the light in your room is bright enough?

[Perli halpern]

 i think the lighting is quite dim actually. and quite yellow. i cant see printed print very well at all but as much as i can see they look fine next to the screen.

I saw somewhere you mention to change light bulbs. could you possibly explain what i should get? Hope my husband wont go mad with me for changing the whole room of bulbs! its 12 bulbs!

Thanks - read it!

Now sorry to sound stupid but what exactly should i ask the store adviser? That i need the lighting in my room to be around 4000-4200 k? 

i need all 12 light fittings to have a bulb so i imagine i need weak bulbs because its so many????

And ill have to borrow a tape measure to measure my room.

 

Sorry for sounding so clueless.

[Damien Symonds]

No, these are very good questions.

If you have 12 light fittings in your room, the bulbs must already be VERY weak, yes?  Have you taken out one of the bulbs to see what strength it is?

[Perli halpern]

No i haven't. 

2 bulbs had gone which we just replaced with bulbs that the landlord left in the cupboard (on the box it says 40W) These  two new bulbs are not exactly the same as the other ones, maybe a bit more white than the others but im assuming theyre about the same... or do u want me to take one out and check? 

 

Thanks so much

[Damien Symonds]

Yes, I think it's important to know what they are, so you don't make the mistake of just getting the same again, you know?

[Perli halpern]

OK I took it out

It says 240V - 60W

 

So I calibrated with 10 of those and 2 of the others all on. 

[Damien Symonds]

Hang on, you should turn them off for calibrating.  Then turn them back on for print comparison, and your usual editing work.

Is that what you meant?

[Perli halpern]

Happens to be I didn't turn off cuz it  said in instructions that u don't have to but u shud N it is anyway not so bright so I didn't bother! 

In my old apartment I always turned it off! This time I did not! 

I can redo it it tomo with lights off but I prob still need to change bulbs so besides redoing it with lights out, what bulbs am I buying? 

 

Sorry for driving  you crazy! Thanks

Again, this statement points to the bigger problem.  You definitely need a brighter room for your editing.  So maybe you need to see if there are 100W bulbs available for your fittings?

 

[Perli halpern]

Oh woops you replied so quickly N I added to my comment in the mean time! Sorry! 

 

If I could get 100W is that gona be fine? N if I can't get, what shud I get? I don't want to be stuck in the shop not knowing what I'm buying because I'm clueless!?! 

 

[Damien Symonds]

Yeah, I reckon 100W, in that 4000-5000 range.

[Perli halpern]

What do u mean in the 4000-5000 range? 

Am I asking shop for 100W bulbs and I should me to on 4000-5000k? 

[Damien Symonds]

Sorry, yes, that's right.

[Perli halpern]

K I'm Confused what I wrote there looks like a typo error - each bulb shud be between 4000-5000k or the whole room? 

I'm guessing the whole room am I right? So all the bulbs together have to add up! Hope the store advisor will help me ?

[Damien Symonds]

K is the temperature.  The colour of the lights.  They should all be the same.

[Perli halpern]

Oh Oh

So each bulb should be between 4000-5000 k and 100W each.

How do i know that 100W x 12 is not too bright ? 

 

[Damien Symonds]

It's actually very difficult to have a room that's too bright. But if you're concerned ... I dunno, maybe go for 80s? But don't risk being still too dim.

[Perli halpern]

Ok then im sure 100W is fine if you say its difficult to have a room thats too bright!!!

Hoping for the best! will let you know when recallibrated with my new bulbs  

Thanks so much off to the shop now

[Perli halpern]

OK np luck with 3 shops. 

Best I found was 40W with 2700k 

It's not theregular bulb so I guess it's hard to find. It's a b22 bulb.

On Amazon I can see it 60W woth  6000K. Is that good? 

[Perli halpern]

Ok Just googled and i think were getting there.

Do you mind to tell me which to go for or have i come up with the wrong stuff? im having a hard time seeing the wattage on some but most of them are 5000K so thats good.

Sorry for all the links - this is a whole new topic for me!!

[Damien Symonds]

Did you ever find a link to the exact bulbs you already have in the room?  I'd be very interested to see that.

[Perli halpern]

I saw them in the shop - didn't look online though. 

Here's a picture of the bulb - im actually in another shop looking now.
