Quick APT question

[Johnboy2011]

Should I be shooting RAW or R+L with my 1000D?

What is RAW + Large?!

Thanks,

I think the L is for saving the image both as a jpg alongside a .cr2 file. I think the jpg is required for image preview to work in APT.

Thanks Andy, I have been shooting in RAW only but I do get a preview of each image after the sub has finished...

[Black Knight]

Dunno then!

Shoot just RAW if you like, but I shoot large JPGs too so I can check focus etc. every few frames.

Cheers

APT can preview RAW files, but it is much slower than previewing JPG file. Also the APT's Image browser will use the JPG version if it exists

Usually I use RAW+L. The disk space is cheap and you can always delete the unneeded files when the session is over...

I have to say I shoot both RAW and Large. Makes it simple to check the focus, composition etc. and check as I go along in windows explorer.

Same here

Thanks for the replies, RAW+L it is then!

You also need the JPEG to get the temperature in the filenames.

Small correction RAWs are needed for temperature readings...

[Johnboy2011]

I see the exif temperature displayed in the APT log as the subs/darks are taken, are they also stored somewhere?

Also should I match my darks temp to the exif temp I see displayed or should I be using an external temp source?

Thanks,

John

Hi John,

You can configure to store the temperature as part of the file name. Note that not all models can determine the sensor temperature (in my site you can find which models have this option)

Some time ago I made a research...

As you can see EXIF is quite accurate if you don't actively cool the sensor

That's great, thanks Ivo.

You are welcome
